Sundance Spas Z-Certify Prerequisite Notes

Prerequisite 1: Glossary of TermsSlide 4:Digital Volt Meter Terms(Alternating Current)

Alternating Current can be defined as a flow of electrons (electric current) that reverses direction in regular intervals or cycles per second. The standard abbreviation for this meter setting is VAC, ACV, V~ or the “Tilde” (~) symbol.

Alternating current is commonly found in normal household outlets. The voltage abbreviation “VAC” can be defined as follows:

120VAC = 120 Volts (Alternating Current)240VAC = 240 Volts (Alternating Current)

Note: Always set the meter to a value higher than the expected reading. Example: Set the meter to the 750VAC range to measure 240VAC. This practice prevents damage to older analog or low cost meters without over-range protection.

Multimeters come in many shapes and sizes. Just a few examples are shown at left. They range from old analog units to fancy new computerized units that can display graphs and complex functions. For the procedures in this course, you should only need a basic digital multimeter. A clamp on unit is best since you may need to measure current. The instructions given for meter use in this course are general guidelines. Please make sure to follow the instructions that came with your particular meter.

Slide 5:Digital Volt Meter Terms (Direct Current)

Direct Current can be defined as a constant flow of electrons (current) in one direction. The standard abbreviation for this meter setting is VDC, DCV, V or .

Direct current is commonly used to power devices such as car stereos and spa stereos. The voltage abbreviation “VDC” can be defined as follows:

12VDC = 12 Volts (Direct Current) 24VDC = 24 Volts (Direct Current)

Note: Always set meter to value higher than the expected reading. Example: Set meter to 20VDC to measure 12VDC.

Slide 6:Digital Volt Meter Terms (Ohms/Continuity)

These terms (Ohms/Continuity) both refer to the measurement of resistance between two points. The standard abbreviation for the Ohms meter setting is the Greek Omega symbol . The standard abbreviation for the Conductivity meter setting is the diode symbol ( ).

Electric current (electrons) require a continuous path or circuit for current to flow. This path can be compared to a water pipe and valve. The pipe represents Conductivity or the means to convey current flow (i.e. metallic fuse or circuit board trace). The Valve represents resistance or the means to slow current flow as it is adjusted. This is the function of components such as resistors and thermistors.

When ready, click on the animation icon at right to start the animation.

Slide 7:Digital Volt Meter Terms (Ohms/Continuity)

The following illustrations show how to test the Thermal Disk, Heater Element and Flow Switch for Ohms or Continuity in applicable spas. Make sure spa power is OFF before testing these components.

Use the Ohms setting to test a resistive device such as a Heater Element, Temperature Sensor or Hi-Limit Sensor. Use the Continuity setting to test a conductive device such as a Thermal Disk, Flow Switch or Fuse.

Note: Orange dots represent meter test points throughout all lessons. Meter lead polarity is not important for resistance and AC voltage (VAC) measurements.

With Power OFF, measure across Thermal Disk contacts for 0 Ohms.

With power off, measure across heater element contacts for expected resistance reading. Refer to STA Manual for details.

When testing a properly functioning Flow Switch, a meter reading of infinite ohms (no continuity) will be measured across wire pins when flow switch is “open.” Then, a reading of zero ohms (continuity) will be measured when flow switch is “closed.”

Slide 8:Resistance Measurements

Thermistors (thermally sensitive resistors) are ceramic semiconductors that exhibit large changes in electrical resistance with corresponding changes in temperature.

These devices are the “active” component used in all Sundance Hi-Limit and Temperature Sensors that monitor water temperature in the Heater and spa.

Since Thermistors are resistive devices, they are tested for resistance (Ohms) to verify proper operation as shown.

Note: The procedure for testing the Hi-Limit and Temperature Sensor is outlined in a future lesson.

Slide 9:Digital Volt Meter Current Measurements

Testing current (amperage or amps) readings, is the actual measurement of current flow (electrons) through a wire, circuit board trace etc.

A clamp-on Current Meter is used to “inductively” measure current flow through a wire of an individual spa component such as the heater, pump motor or blower motor. When a clamp-on meter is used, only one load wire of the tested component is measured for current draw.

Slide 10:Hi-Limit Sensor

Sensor that monitors water temperature inside the spa heater to prevent overheating and freeze damage. Sensor mounting locations include:

• All 980 and 880 Spas: Sensor mounts inside a well in the plastic heater assembly (shown)

• All Select, 780 And 680 Spas: Sensor is strapped to the metal heater body.

Sensors used on all spa models are identical with the exception of their wire pin connectors. These differences will be explained on a future slide.

Slide 11:Temperature Sensor

Sensor that monitors water temperature inside the spa seating area and is located in the spa filter bay in all 980, 880, Select and 780 spas. In 680 spas, this sensor is mounted in various interior positions depending on model.

The temperature sensors used on all spa models are identical with the exception of their wire pins. These differences will be explained on a future slide.

Slide 12:Flow SwitchAll 980, 880, Select, convertible 780, 2006 - 2012 Circulation pump equipped 680, pre-2017 240V 780, March 2020+ 240V 780, and September 2020+ 680 models use a Flow Switch to monitor water movement through the heater.

During normal operation, water flows from the circulation pump, through the heater and Flow Switch. This movement forces the Flow Switch paddle to rest against the switch body which closes an internal reed switch to signal the circuit board that the Heater can safely energize. Insufficient water flow prevents Flow Switch contact closure and prevents heater operation and damage.

The Flow Switch mechanism used on these spa models is identical but their wire pins are different. These differences are outline on a future slide. Note: the Flow Switch is always installed with direction arrow pointing away from the heater.

Note: The Flow Switch used in all All 980, 2016+ 880, and all 2017+ 780 and 2020+ 680 models use curled finger wire pin connectors and include a factory installed cable connector.

Note: The Flow Switch used in all 2015 and older 880 models used boxed wire pins connectors for installation into a main sensor harness connector as outlined on a future slide in this lesson.

Prior to 2008, the bottom flow switch barb required:1. A plug 6540-101 is glued into the 3/8” barb fitting and a 3/32” hole is drilled through it. 2. 2008+ Flow Switch housings 6560-860/ 2560-040 include a restricted 3/8” barb. No plug or drilling is required. The 780 Dover uses Flow Switch 6560-852 with no 3/8” barb.

Slide 13:Pressure Switch

A Pressure Switch is used to monitor the presence of water flow (pressure) inside the spa heater in the following spa models:

• All 2017 - February 2020 780 2-pump dedicated 240V models*.• All 2006 - 2017 non-circulation pump 680 series spas.• All 2018 - August 2020 680 series spas.

The Pressure Switch attaches to the spa heater through the rear load box wall.

*Note: All 2017+ 780 1-pump convertible Dover models use a Flow Switch instead of a Pressure Switch as outlined on the previous slide.

View the chart below for a breakdown of which spas use a flow switch and which use a pressure switch:

Slide 14:Sensor Wire PinsThe wire pin connectors used on all hot tub sensors vary by model and year as explained below:

Box Pin ConnectorsUsed exclusively on: 1. All 2015 and older 880/850 Hi-Limit Sensors (no plug)2. All 2015 and older 880/850 Temperature Sensors3 All 2015 and older 880/850 Flow Switches

Slide 15:Circuit Board

Printed wiring assembly (PWA) that distributes voltage to selected spa components.

Note: Older 2008-2009 880/850 Circuit Board with Eprom shown for illustration purposes only.

Slide 16:Dip Switch Assignments

A bank of numbered switches on the hot tub circuit board that create logic changes. Used by all current spa models.

These switches enable various logic changes stored on the Circuit Board Microprocessor, such as 60 Amp logic, Fahrenheit temperature display etc.

Jumpers (as described on the previous slide) may also appear on these circuit boards to perform a specific function, such as a factory software reset, but basic logic selections are now performed via the dip switch bank.

Slide 17:CD Ozone Generator

Device that changes oxygen (O2) into ozone gas (O3) through the principle of high voltage corona discharge.

Ozone is a powerful “oxidizer” that breaks up dead organic matter and bacterium which is then collected on the filter cartridge surface. An approved sanitizer such as chlorine or bromine MUST still be used to kill water borne bacteria and micro organisms.

Our CD Ozone Generators are compatible with all 2011 and older models. Note: Using these devices reduces sanitizer chemical use in your spa.

Slide 18:Circulation Pump

The Circulation Pump is the primary filtration and heating pump in all 980, 880 and 780 series that spas.

Details for the operation of this pump will be discussed in future lessons. Note: 2013+ 680 models no longer offer a Circulation Pump option.

Note: Refer to the illustrated parts catalog for Circulation Pump options.

Slide 19:Filter Cartridges

The Filter Cartridge removes dirt and oils from the spa water. One style is used for all 980 models. Two styles are used for all 2005+ 880 models:

980 And 2009+ 880 Models:These models both utilize the MicroClean® Ultra Filter Cartridge System illustrated at right.

2009+ 880 Models: These models utilize the MicroClean® Ultra Filter Cartridge System illustrated at right.

2005-2008 880 Models: These models utilize the MicroClean® Plus Filter Cartridge illustrated at right.

Slide 20:Filter Cartridges (Continued)

Two styles are used for current Select, 780 and 680 models. Descriptions are as follows:

Select And 780 Models:These models utilize the MicroClean® I filter cartridge system illustrated at right. Note: The MicroBan (spun bound) element used in Select models differs from the element used in 780 models due to their high flow circulation pump. This is the smaller of the two cartridges illustrated at right.

680 Models:These models utilize a standard pleated filter cartridge illustrated at right.

Note: Older 850 models also use the MicroClean® I Filter Cartridge System from 2002-2005.

Slide 21:Skimmers

All Sundance spas have “skimmers.” These devices float up and down depending on water level to pull off small particles and oils from the water surface and trap large debris inside the filter bay. This action ensures maximum water clarity.

980, 880, And Select Models The filtration pump pulls water over the “skimmer” into the filter.

780 And 850 Models Circulation pump and jet pump 1 pull water into the filter area during a programmed filter cycle or during spa use.

680 Burlington, Hartford And Hawthorne Models (2008+)Circulation pump and jet pump 1 pulls water over the skimmer door into the filter area.

680 Edison, Denali, Peyton, Tacoma Models Jet pump 1 pulls water over the “skimmer” cylinder into an underlying filter cartridge during one of four programmed filter cycles or during spa use.

Slide 22:SunSide™ Cabinets:

Starting with the 2019 model year, the 880 Altamar, Cameo, Cambria, Marin, Optima, and Capri models can be ordered with an optional premium cabinet called SunSide™. This cabinet requires no screws and is designed to be easy to remove for access to the spa’s equipment and plumbing.

These cabinets come with special corner lights.

Note: The rest of the 2019+ 880 models are not available with factory installed exterior corner lighting. A 2019+ circuit board is REQUIRED for these lights to function. Although a 2018 circuit board will physically connect to a 2019 880, the zone 2 circuit is modified on the 2019+ version specifically for these lights. Models with the standard cabinet are still compatible with the older style (pre-2019) corner lights, which are available as an aftermarket kit.

In 2020, the SunSide™ cabinets became standard on the entire 880 series, including the Maxxus and Aspen.

Slide 23:Frog @ease Holder

Beginning in 2021 (on U.S. models only), 980, 880, and 780 series spas come factory-equipped with a holder for SmartChlor and mineral cartridges.

Sunpurity is also still available.

Slide 24:980 And 2016+ 880 Series Sensor Connections

All 980 and 2016+ 880 series spas utilize three Sensor Connectors (plugs) on the Circuit Board as illustrated at right. These plugs represent the point where each sensor connects to the Circuit Board.

Note: The Circuit Boards used for all 2017+ 980 and 2016+ 880 systems are similar in appearance and layout but are not interchangeable due to software and jumper variations between models.

• J9 Plug: Connects Flow Switch wires to the Circuit Board.

• J17 Plug: Connects Temperature Sensor wires to the Circuit Board.

• J18 Plug: Connects Hi-Limit Sensor wires to the Circuit Board.

Note: All 980 and 2016+ 880 sensors include factory installed wire pins and connector plugs on their cable ends (not shown). The sensor plugs for these models require special handling when disconnecting them from the circuit board as outlined on a future slide in this lesson.

Slide 26:Important Sensor Connector Removal Instructions

Temperature Sensor And Flow Sensing DeviceThe Temperature Sensor and Flow Sensing Device used by all 980, 2016+ 880, 2017+ 780, and 2018+ 680 models includes a factory installed Sensor Plug as illustrated (Fig. A). This plug contains a locking mechanism that makes it impossible to remove from a mating circuit board connector without special handling as follows:

Plug Removal Procedure1. Locate the white Sensor Plug on the circuit board (Fig. A). Note: Refer to the previous slide for the exact location of the Temperature Sensor and Flow Switch sensor plugs as needed.2. Insert a small screwdriver tip under the Sensor Plug Tab as illustrated (Fig. B), then gently pry outward approximately 1/16” and hold in place, then grasp the Sensor Plug with your other hand and gently pull it from the mating circuit board connector.

Hi-Limit Sensor PlugThe Hi-Limit Sensor used by all 980, 2016+ 880, 2017+ 780, and 2018+ 680 models includes a factory installed plug that uses a different locking mechanism than the Temperature Sensor and Flow Sensing Device. It also locks onto the mating circuit board connector and cannot be removed without special handling as follows:

Plug Removal Procedure1. Locate the black Hi-Limit Sensor Plug on the circuit board (Fig C). Note: Refer to the previous two slides for the exact location of the Hi-Limit sensor plug as needed.2. Using your thumb or a pair of needle-nose pliers, grasp and squeeze the Hi-Limit Sensor Plug Tab inward and hold as illustrated (Fig. D), then gently pull both the pliers and the Sensor Plug from the mating circuit board connector.

Note: You can damage the sensor wires and/or mating circuit board connectors if you pull them off of a mating circuit board connector without first performing the procedures outlined above.

Slide 27:Touch-Screen Control Panels

Touch-screen style Control Panels are used on all 980 and 2016+ 880 series spas to access all spa functions. Each version includes the following features:

• Full Color, Back-lit, Liquid Crystal (LCD) Display

• Touch-Screen Programming

• Graphic Icons that aid in setup, indicate feature activation and display system errors.

LCD Control Panels

LCD Control Panels are used on all 2017+ 780, 2018+ 680, and 2020+ Splash series spas. They include basic icon indicators and add scrolling display messages to aid in setup and operation.

Slide 28:Encrypted Circuit Boards and Topside Control Panels

Balboa encrypted circuit boards and control panels are used in all current Sundance Spas models.

Encrypted control panels will work with older model, non-encrypted circuit boards, but non-encrypted control panels will NOT work with encrypted circuit boards.

A Pick-It Kit (described later in this lesson) will allow you to reprogram a non-encrypted board to the current encrypted software revision.

Models that previously required a passcode to activate will no longer need one when outfitted with the encrypted equipment. This applies to both spas shipped from the factory with encrypted circuit boards and spas in the field that have been serviced with encrypted circuit boards.

The date when encryption became standard varies by spa model:

Slide 29:Field Upgrade Procedure for Current ModelsA Field Software Upgrade Kit (6000-819) is available for all 980, 2016+ 880, 2017+ 780, and 2018+ 680 models should a new software release become available in the future. This kit includes: 1. One PICK iT-3 Device 2. One Communication Cord 3. One USB Power Cord

Important: Pick-iT kit software is specific to the spa series (i.e. 980, 880), the software revision, and whether the board software to be used is encrypted or not. Software must be pre-loaded for the proper model and revision from the internet prior to service.

Note: The PICK iT-3 Device included in this kit can be reprogrammed as new software revisions are released. To verify if you have the latest software revision for the spa in question, please visit the following web site at: www.microchip.com/mplabx or contact the Technical Support Department for details.

Software Update Procedure1. Turn off hot tub power. Connect the supplied USB Power Cord to the top port on the PICK iT-3 Device (Fig. A). Connect the opposite end of the cord to a USB power source such as a Cellphone USB Wall Charger, Laptop Computer USB Port, or Desktop PC USB Port (Fig B). Do not apply power to the USB Power Source at this time.

2. Attach the supplied Communication Cord to the bottom port on the PICK iT-3 Device by aligning the arrow on the device with the “Pin 1” marking on the cord (Fig. C). Note: Both markings must align. Connect the opposite end of this cord to the Circuit Board’s “J1” Connector (Fig. D). Note: The “J1” Connector is keyed for one-way installation, do not force!

3. Change Dip Switch SW7 the Circuit Board from Normal Mode (left) to Demo Mode (right) as illustrated (Fig. E). Do not change any of the other DIP Switch setting. Apply power to the PICK iT-3 USB Power Source connected in step 1. The PICK iT-3 LEDs change as follows: A. All three LEDs turn on after a few seconds, B. POWER LED turns GREEN ► ACTIIVE LED flashes BLUE ► STATUS LED turns OFF (Fig. F).


s

Slide 30:Field Upgrade Procedure for Current Models (Continued)

4. Turn on hot tub power. The Topside Control Panel Display displays “Panel Com. Error” and is locked (this is normal). Press and release the black PICK iT-3 Button (Fig. G). The PICK iT=3 LEDs and the Topside Display change as follows: A. POWER LED = GREEN ► ACTIVE LED = BLUE ► STATUS LED = RED. B. POWER LED = GREEN ► ACTIVE LED = Flashing BLUE ► STATUS LED = GREEN (Fig. H). C. The Topside display changes back to the Welcome Screen and displays software revision “Spa 1.14” (or higher). This event confirms the programming process was successful (Fig. I).

If the PICK iT-3 Device’s STATUS LED is flashing RED, and the spa continues to display “Panel Com. Error”, programming has failed. If such cases, you must turn off hot tub power and disconnect the USB Power Source from the PICK iT-3 Device for 3-5 seconds. Recheck the Communication Cord connection at the bottom of the PICK iT-3 device for proper orientation as outlined in step 2. Finally, you must repeat steps 3-4 until successful programming is achieved.

5. Turn off hot tub power. Change the Circuit Board Dip Switch SW7 back to the “Normal” (left) position (Fig. E). Unplug the USB power source from the PICK iT-3 Device, then disconnect the supplied Communication Cord from Circuit Board Connector “J1” (Fig. D). Turn on hot tub power. Verify the startup Welcome Screen displays software revision “Spa 1.14” or higher (Fig. I). Finally, test all spa functions before leaving the work site to complete this procedure.

Slide 31:On-Board Transformers

The Circuit Boards used in all 980, 2016+ 880, 2017+ 780, 2018+ 680, and 2020+ Splash models use an on-board transformer (outlined in red) as illustrated at right. This component transforms high voltage AC from the main Terminal Block TB1 (outlined in orange) to a lower AC voltage to power the spa circuit board.

Slide 33:CLEARRAY® Water Purification/Filtration System

All 2012+ models include the CLEARRAY® Water Purification System. This system’s high intensity UV-C ultraviolet light interacts with the DNA of bacteria and viruses to destroy their ability to reproduce. Neutralized water is then injected back into the hot tub where a standard sanitizer such as bromine or chlorine quickly oxidizes/kills the remaining organisms.

CLEARRAY® Advantages Over Conventional Ozone Systems• The CLEARRAY® system produces no off gassing of any kind which can affect plastic components.• The CLEARRAY® System does not require a ozone/mazzei injector which may clog over time and may require periodic maintenance.

Note: This system reduces sanitizer chemical use in the hot tub. It is important to note that a residual sanitizer such as chlorine or bromine is still required. The CLEARRAY® Water Purification System requires yearly bulb replacement and quartz tube cleaning.

CLEARRAY® On Demand:2019 and up spa models with software revision 2.05 or higher and a CLEARRAY® On Demand button now have 3 modes for this system:

Optional CLEARRAY PRO3TECT™ Low Output Ozone SystemThis accessory is designed as a supplement to our state-of-the art CLEARRRAY® Water Purification System. It offers a second level of sanitation for customers that wish to use traditional ozone with their CLEARRAY® Water Purification System.

ClearRay UV and ClearRay Pro3Tect are included on all 2021 models except the Splash Series (which has optional ozone only) under the name ClearRay Active Oxygen, with the ozone plumbed BEFORE the UV.

Splash Series spas do not use a DCU or adapter. The footwell light plugs directly into a dedicated harness on the circuit board. Waterfall and exterior lights are daisy chained from the footwell light.

DCU Expansion Adapter for 2016+ 3-Pump 880 Maxxus/Aspen Models (12VDC)This device basically acts like a large power strip for most 2016+ Maxxus/Aspen lighting components. It contains seven ports that are used as connections for all multi-colored LED light components.

A single connector at the bottom of this device plugs directly into the Zone 1 Circuit Board connector. The Circuit Board supplies 12VDC power to each interior light. All light system settings and operation commands are controlled by the Circuit Board’s microprocessor (not this device).

Note: The Zone 2 connector on the 2016-2019 Maxxus/Aspen Circuit Board is used for the accessory step light.

DCU Expansion Adapter for 2016+ 2-Pump 880 and all 2017+ 780 Models (12VDC)This device acts like a large power strip for most lighting components. It contains six ports for all multi-colored LED light components.

One connector at the bottom of this DCU Expansion Adapter plugs directly into the Zone 1 Circuit Board connector. The spa Circuit Board supplies 12VDC power to all interior lights. All light system settings and operation commands are controlled by the Circuit Board’s microprocessor (not this device).

Note: The Zone 2 connector on the 980 and 2016-2018 880 2-Pump spa Circuit Board is used for the accessory step light.

2019+ 880 Models With Optional Cabinet and Corner LightsModels equipped with the SunSide optional cabinet will use TWO of these expansion adapters. One plugged into zone 1 of the circuit board to power the interior lights, the other plugged into zone 2 to power the cabinet corner lights. Spas equipped this way are NOT compatible with the accessory step light.

Slide 35:BLUEWAVE™ 2.0 Stereo Option (880/980 Series)

The BLUEWAVE™ 2.0 Stereo is used on all 980 and 2016+ 880 models with the stereo option. This basic stereo option offers the following features:

Bluetooth® Output: Stream audio up to 30 feetNo wireless remote option is offered with this stereo system.No AM/FM Radio ReceiverNo CD PlaybackOPTIONAL: A remote kit is available for these stereos as an optional add-on part.

This audio system will also be covered in a future lesson in this training series.

Note: To access the Auxiliary Input Jack on the BLUEWAVE stereo, the front spa access panel must be removed.

Note: A patch kit including a remote was used to fix “stereo communication” errors until an update to the 6500-917 units was completed. 6500-917 stereos made after 06/2018 (Rev. 5) have a new sofware revision to eliminate this error without the use of the patch kit.

Function similarly to the 780 Series units, but have no FM Radio, USB connection, or remote control. Can be controlled only via BlueTooth, or with a device connected to the 3.5mm input jack.

Running Line Change to 2019+ Stereo Units

In July of 2019, the stereo on 680 and 780 models was upgraded to a new unit which does not have an external door. It is enclosed completely behind the spa’s cabinet and no longer has FM Radio, USB connectivity, or an external 3.5mm input. It offers a cleaner look, enhanced sound on 780 models with a subwoofer, and is available with a rechargeable remote.Note: 3.5mm auxiliary inputs can still be plugged into the stereo if accessed through the equipment bay, however, this will require a 3.5mm mini to RCA stereo adapter.Important: 680 series service parts for older stereos are no longer available. If upgrading an older spa to this stereo system, a new cabinet door without the stereo cutout is required.
