Page 8: Installation
INSTALLATION Take off the small cover on the top of the damper controller. Allocate and set unique addresses to all zones with consideration of spill privileges for the zones. Please refer to the Zone Address section for details. Please note that bypass damper has a special address as shown in Figure 3. Page 5... - Page 9 Mount the damper controller on the top of the motorised damper, or installed elsewhere close to the motorised damper. Plug the bridge cable into the damper port on the damper controller and the motor. Warning - Do not plug the damper controller into any other motorised damper except a Polyaire authorised one. Apply the power to the transformer by plugging in the transformer into the 240VAC power outlet. Plug the 24VAC power supply into the socket on the last damper controller at the end of the control bus. The LED light on the damper controller should be on. Otherwise, check the power supply and the connection. Page 6...
- Page 10 Use a pre-tested cable to connect the last damper controller with the next one. The LED light on the next damper controller should also be on. If not, check the cable and the connection. Repeat the step 6) until all damper controllers are connected together in series and all LED lights are on. Use another pre-tested cable to connect the touchpad with the first damper controller as shown in Figure 1 or in the middle of the control bus via a double adaptor as shown in Figure 2. Page 7...
- Page 11 Check all the LED lights on the damper controllers again. If some of the lights are off, the cable to the first off-light damper controller could be crossed over. Check and replace it. 10) Repeat step 9) until all of the lights are on and the LCD screen on the touchpad shows clock time and the room temperature where the touchpad is located after showing “initiate” on the second line for about 15 seconds. Hold down both and buttons on the touchpad for about 5 seconds to enter the setting mode (refer to next section). Check all the LED lights on the damper controllers again. All of the LED lights must be flashing in one-second interval. Otherwise, check the cable and the connection. Turn off the power and disconnect the touchpad. Position the touchpad at the right place. Ideally, its position is approximate 1.6M off the floor on the wall. Fit the cable through the wall cavity and connect the touchpad again. Apply the power again to the transformer. The LCD should show clock time and temperature. If not, check the cable. Mount the supply air sensor in the supply air duct upstream the motorised damper. Fit the sensor cable through the wall cavity and plug into the socket on the back of the touchpad. Connect the battery by plugging into the socket on the back of the touchpad. battery sensor Page 8...

Page 12: Zone Address And Allocation
Mount the touchpad onto the bracket in the wall cavity. Please note that the touchpad should not be exposed to direct sunlight and other heat sources. ZONE ADDRESS AND ALLOCATION Each damper should have a unique address in the serial control bus to be identified by the touchpad. This address is configured by a standard 4-way DIP switch inside the damper controller to provide 8 unique normal zone damper addresses and a special address for the bypass damper. All damper addresses can be set as shown in Figure 3. When allocating address to each zone in spill mode, it is strongly recommended to give lower addresses to those zones that have higher spill privileges. The lower the address, the higher the spill privilege the zone has. When the spill setpoint is reached, the touchpad instructs zone 1 to open as spill. If the first spill zone cannot satisfy the spill air control, the zone 2 will be instructed to open to spill excess air. This process will continue until the spill air setpoint is satisfied in the system. Such a spill air control strategy implemented in the Zonemaster UniPoint control system requires the installer to allocate the zone 1 near the return air grilles. Figure 3.

Page 13: Recommended Commissioning Procedure
RECOMMENDED COMMISSIONING PROCEDURE 1. Initiating and Exit Setting Process The Zonemaster UniPoint has several parametres that must be set in the commissioning stage. 1) Hold down both and buttons for about 5 seconds until the LCD displays ‘Setting’ on the top line of the LCD screen. 2) At the setting mode, pressing button at any time will return to the normal operation mode. 2. Room Temperature Sensor The touchpad has an onboard sensor to measure the temperature of the room for indication purpose. The sensor can be calibrated by the parameter and provides more accurate temperature display. 1) Using an accurate probe to measure the temperature of the area you want to calibrate and record the value. 2) At the setting mode, press button until the LCD displays the ‘Sensor’ screen. 3) Press or button to adjust the displayed value to the record value. -
Page 14: Supply Air Safety High & Low Limits
4. Supply Air Safety High & Low Limits For safety reasons, the system monitors the supply air temperature closely. If the temperature moves outside of the limits, all dampers in the system are forced open and the LCD displays ‘Safety’ on screen. The factory default supply air safety high & low limits are 60 C and 5°C respectively and safety control is disabled. 1) At the setting mode, press button until the LCD displays the ‘H_limit’ screen. 2) Press or button to change the high limit to the desired value. The adjustable range of the high limit is from 45°C to 75°C. 3) Press button once again, the LCD screen will display the ‘L_Limit’. 4) Press or button to change the low limit to the desired value. The adjustable range of the low limit is from 0°C to 15°C. If the customer does not want the safety function, the supply air sensor is not needed to be installed. The safety H_limit and L-limit MUST be disabled by pressing button during the setup. - Page 15 Spill mode uses the zones with the lowest addresses in the system as spill zones that will be automatically forced to open if the total number of open zones is less than its setpoint. In bypass mode, a bypass damper is used to return the air directly to the duct if the total number of open zones is less than its setpoint. The bypass damper is also serially connected with other dampers and has a special address as mentioned before. 1) At the setting mode, press button until the LCD displays the ‘Spill’ or ‘Bypass’ screen. 2) Press button to select spill or bypass mode. 3) Press and button to change the spill/bypass setpoint to its desired value. The adjustable range is from 0% to 50%. If no spill or bypass control is required in the system, the setpoint MUST be set to 0. Page 12...

Questions and answers
We set living zone to off but still comes on
The Polyaire Zonemaster Unipoint living zone may turn on even when set to off due to the spill mode function. In spill mode, zones with the lowest addresses are automatically forced to open if the total number of open zones is less than the spill air setpoint. This ensures proper duct pressure relief and system efficiency. If the living zone has a low address, it may be designated as a spill zone and activated automatically when needed.
