The following notes should be considered when using Room Pressure Control:

12. Pressure Mode – General Notes

1. Main Screen Icon – Room Pressure Setting: -

Set to Negative – High pressure Alarm = High Negative pressure e.g. -20Pa / Low pressure Alarm = Low Negative Pressure e.g. + 1 Pa. Typically set for a room operating on a Negative Pressure Set Point.

Set to Positive – High pressure Alarm = High Positive pressure e.g. +20Pa / Low pressure Alarm = Low Positive Pressure e.g. - 1 Pa. Typically set for a room operating on a Positive Pressure Set Point.

2. Input Screen Icon – Min and Max Range Settings: -

Ensure the ranges are set to match the Pressure Sensor Range e.g. +/- 25 Pa or 0-50 Pa etc

3. Control Screen Icon – Proportional Band and Integral Time Settings: -

Prop Band – the Proportional Band is the gain of the output, increasing the value will give slower control.

Integral Time – the Integral action corrects errors over time – increasing the value will speed up the corrections

To establish good control set the Integral to zero and set the Prop Band to give stable control, once the Prop Band is set increase the Integral so the control maintains the set point in a reasonable time without hunting.

When the AFA5000 is set to volumetric control mode the controller will control any combination of the supply and exhaust air volumes based on volumetric demand.

15. Volumetric Mode – Operation

The Supply Air can be controlled by volumetric set point or pressure override:

a.SupplyAircontrolvolumetricsetpoint-Volumeoffsetofthetotalexhaustfromtheroomspace.

b. Pressure Override Control increases or reduces the Supply air set point if the room pressurization has priority over volumetric control.

The Room Exhaust can be controlled by a combination of demand signals:

a. Minimum Exhaust set point – when the Fume Cupboard exhaust drops below the set point the Room Exhaust will increase to maintain a minimum exhaust from the Room.

b. CO2/Humidity/VOC/Cooling can be set to operate the Room Exhaust to increase Air Changes on a highest demand basis.

Additional volumetric inputs can be set: -

a.DigitalInput1–Canbesettoswitchedinpute.g.flowswitch(addedtototalFumeCupboard volume)

b.DigitalInput2–Canbesettoswitchedinpute.g.flowswitch(addedtototalFumeCupboard volume)

c. Expansion PCB – Can be set to: Additional Supply Air / Exhaust Air feedback I/Os or as VAV analogue volumetric inputs (added to total Fume Cupboard volume).

Room Pressure Control Logic


The following notes should be considered when using Volumetric Pressure Control:

16. Volumetric Mode – General Notes

1. Supply Air I/O – Input / Output settings: -

Each supply air Damper/Valve/VAV Box/VFD connected to the AFA5000 will have its own dedicated 0-10V control output signal and 0-10V feedback input signal. Supply Air 1 and Supply Air 2 are dedicated I/O on the Main PCB for the primary I/O, additional I/O can beusedwiththeExpansionUnit.TheExpansionUnitI/Ocanbeconfiguredformultiplefunctions so require set up for Supply Air.

ThefeedbackinputintotheAFA5000canbedoneusingaflowgrid,orificetyperestrictorora linear 0-10V signal from a VAV box or VFD. The feedback input parameters allow each input to be set up independently of each other.

The output control signal (PID or Demand output control) is common to each assigned output but each output can be limited or scaled independently of each other.

2. Exhaust Air I/O – Input / Output settings: -

Each exhaust air Damper/Valve/VAV Box/VFD connected to the AFA5000 will have its own dedicated 0-10V control output signal and 0-10V feedback input signal. Exhaust Air 1 and Exhaust Air 2 are dedicated I/O on the Main PCB for the primary I/O, additional I/O can beusedwiththeExpansionUnit.TheExpansionUnitI/Ocanbeconfiguredformultiplefunctions so require set up for Exhaust Air.

The output control signal (PID or Demand output control) is common to each assigned output but each output can be limited or scaled independently of each other.


3. Digital I/O – Input settings: -

Digital Inputs 1 & 2 can be assigned as a Purge input or additional Fume Cupboard Exhaust volume. In Purge mode, the Room Exhaust will operate to the set Purge volume.

4. Analogue VAV I/O – Input settings: -

Expansion Unit inputs 9-14 can be assigned as VAV inputs, these are scalable 0-10V inputs that are added to the Fume Cupboard total volume.

5. Demand functions: -

The CO2 and VOC control is done via increased air changes and will increase the Room Exhaust Air output to the point where the total room exhaust matches the maximum supply air volume so that the room pressurization is not compromised. Cooling and Humidity can also be set to operate the Room Exhaust output.

Where multiple Room Exhaust functions are assigned the controller operates on a highest demand basis and will control to maintain the set point of the function with the highest demand, once the level is reduced the next highest demand function has priority control.

6. Eco Mode functions: -

The controller can be set to operate on 3 modes, Occupied, Unoccupied and Setback. Each mode has its own Set Points and Alarm Points for inputs and outputs. The following is adjustableinECOmodeoperation:-

ECO Mode – Adjustable Set Points (Occupied / Unoccupied / Setback)

The AFA5000 has a CO2 input function that can be used to Monitor or Control CO2 levels in the room. To Control the CO2 level the controller uses the Room Exhaust Air output to increase the air changes in the room, the Exhaust Air volume will be limited by the Supply Air maximum volume so that the room does not over pressurize.

The AFA5000 has a VOC sensor input function on the Expansion Module that can be used to Monitor or Control VOC levels in the room. To Control the VOC level the controller uses the Room Exhaust Air output to increase the air changes in the room, the Exhaust Air volume will be limited by the Supply Air maximum volume so that the room does not over pressurize.

The Exhaust Air will be controlled on a demand basis with the highest demand function taking priority.

The Exhaust Air will be controlled on a demand basis with the highest demand function taking priority.


The AFA5000 has a Room Pressure Override feature that will increase or decrease the Supply Air Set Point in time steps once the Room Pressure Override Set Point has been reached.

22. Room Pressure Override

a. For a Negative pressure room: -If the room becomes less negative e.g. + 1 Pa, the pressure Override will deduct the set volume from the Room Supply Set Point over the set time steps.

If the amount of volume deducted exceeds the set alarm limit the pressure Override alarm will activate.

b. For a Positive pressure room: -If the room becomes less positive e.g. - 1 Pa, the pressure Override will add the set volume from the Room Supply Set Point over the set time steps.

If the amount of volume added exceeds the set alarm limit the pressure Override alarm will activate.

Once the Pressure Override has activated the controller will try to reduce the Set Point offsetthatisaddedbythePressureOverridesothattheSetPointwillreturntoVolumeonly once the over or under Pressurization error has been corrected.
