The Device


1 The Device

This section contains a short overview of the display and hardware functions of the device.

1.1 Function Overview

Heating & Cooling IndicatorsRed and blue semi-circles indicate if device is heating (red), cooling(blue), or idle (both off).

Room TemperatureLarge number in middle of display shows current home temperature.

Setpoint TemperatureSmall number above large number is desired temperature. Use arrowsto change. Both setpoint and arrows appear when your hand nearsdevice. Note: Setpoint can be changed in device settings.

SettingsTap to activate or deactivate function. Switch between “active view”and “settings view”.

Heating & CoolingTap to enable or disable heating/cooling mode.

FanFan can be set to ON or AUTO mode. By default, it is in AUTO mode.Tap to turn ON the fan.

The Device


EcoAt night or when operator is away, device can be set to save energy.Tap to activate. Setpoint is automatically decreased (for heating) orincreased (for cooling).

ON/OFFTap to turn Thermostat ON/OFF and to turn ON/OFF all appliancesconnected to it. Only House Protection function remains active.

Accessory ApplianceTap to activate or deactivate an additional function, (i.e. humidifier orde-humidifier).

Auxiliary heating / Emergency HeatingUse only if heat pump is controlled. If symbol is ON, auxiliary heatingis enabled. Auxiliary heating allows supplemental source (electric orgas heater) to support heat pump if needed. Auxiliary heating can beenabled manually by user or automatically by HVAC control.Press and hold symbol for 3 seconds to activate “Emergency Heating”.Use to heat house but prevent compressor from turning ON. Use whencompressor is defective or iced due to extreme winter temperatures.Symbol will blink when Emergency Heating is active.House ProtectionIndicates heating/cooling was turned ON automatically to protectHVAC from overload and home from extreme hot or cold temperaturesfor one of these reasons: 1) To protect house from freezing oroverheating; or 2) To protect HVAC equipment from overload ordamage. House Protection stays ON, activate in settings.

1.2 Always-ON Functions

Proximity SensorAs the user’s hand approaches the display, it wakes-up andshows touch controls. Proximity sensor is located near bottomof device.

Self-Adjusting Display Brightness Display adapts to fit light level of room. Brightness level can bechanged in settings.

Adding the Thermostat


2 Adding the Thermostat

STEP 1: Install the ThermostatWARNING: Installation must be performed by a licensed HVAC installer or electricalprofessional. Improper installation can cause property damage, personal injury, or loss of life.

Install the device by following the Operating Instructions and Wiring Guide included in theoriginal packaging. After wiring is complete, take a photo of the connected wires and save forfuture use.

Note: When first powered, the device is in discovery mode for 30 minutes. This time periodallows the SysAP to see and connect to the device. During this time, the user can login to theSysAP and add the device to the free@home network. If the Thermostat has been assigned toa different SysAP, it will need to be reset. Please see here for instructions.

STEP 2: Open configuration and search for the Thermostat

Ensure that the SysAP is in Access Point mode by pressing the button on the SysAP. Theindicator light will turn solid blue. Connect to the SysAP by selecting it from the list in yourwireless network.

Once connected, open a browser and enter 192.168.2.1 in the address line.

If you have a tablet, use the free@home App.

Note: it is not possible to set up the Thermostat by using a smartphone.

Log in as a user that has configuration rights.

https://search-ext.abb.com/library/Download.aspx?DocumentID=9AKK107046A6575&LanguageCode=en&DocumentPartId=&Action=Launch



Start Go to Settings > free@home radio > Search for wireless devices

The SysAP will now search for the Thermostat.

Note: The Thermostat can only be found if the search starts within 30 minutes after theThermostat was connected to power. If the 30 minutes has elapsed, pull the Thermostat fromthe wall and plug it in again to restart the 30 minutes.

The Thermostat will be found automatically and will be inserted into the configuration software.

Please wait until the Thermostat configuration is read. This may take up to 10 minutes.

STEP 3: Add the Thermostat to the floor plan

A. Go to “Devices”.

B. Click on “Temperature control”.

C. Click on “Thermostat”.

D. Drag the Thermostat symbol into the floor plan.

E. Choose the device from the list.

Note: The device can be identified by its serial number or 3-digit code.



G. A new symbol will appear in the floor plan.

2.1 More than one Thermostat (“Master & Slave“)

Of course you can have more than one Thermostat. There are two options:

OPTION 1: There are 2 (or more) Thermostats for the same HVAC equipment

If you only have one HVAC equipment but want to have 2 (or more) Thermostats for controllingit, make one Thermostat the “Master” and the other one(s) a “Slave”. This is done duringconfiguration (see next chapter).

Important: The control wires must be connected to the “Master” Thermostat. The Slaves onlyneed 24 V AC connected to the Rc and C terminals. Master and Slave will show the sameinformation on their display.

See the example above: The Thermostat in the Hall is the “Master”. The Thermostat in theMaster Bedroom is the “Slave”.

OPTION 2: There are 2 (or more) HVAC equipment in the house

If you have 2 (or more) HVAC equipment (e.g. one for the 1st floor and another one for the 2nd

floor) configure both Thermostats as “Thermostat”.

Configuring the Thermostat


3 Configuring the Thermostat

STEP 1: Start the Configuration Wizard

Follow the instructions of the Configuration Wizard. To start the Wizard, click on the Thermostatsymbol in the floor plan, then click “Configuration” in the menu that appears on the right.

After the configuration is complete, the Thermostat will appear in the DEVICES List View:

Once you add a second Thermostat you will be asked if it is a Master or a Slave:

Please refer to section 2.1 for more information on “Master” and “Slave”.

STEP 2: Adapt the Settings, if required

The following table shows the Thermostat settings.
