APPLICATION The Zonemaster VAV (Variable Air Volume) is a fully featured system designed to accurately manage air flow by zone in Ducted reverse cycle, heating and evaporative air conditioning systems. It manages airflow from the A/C unit by assessing temperatures in each zone and opening and closing dampers to increase or decrease airflow to achieve and maintain a preset temperature in that zone.
COMPONENTS 1) Main Controller The main controller collects and processes all the information. 2) Master Touchpad 6 button touchpad. To program and control all the zones in the system. 3) Zone Touchpad 3 button touchpad. 4) Bypass Damper and Controller (optional) Green Damper controller receives bypass control signal from the main controller to open or close the bypass damper. 5) Supply Air Sensor Supply air sensor measures the temperature of the supply air. 6) Power Supply The 24VAC transformer provides power to the first 8 touchpads - dampers and main controller.
CONFIGURATION Main controller collects and processes all the information. The connections to the main controller are shown in Figure 1. Figure 1. Main Controller Connection Diagram Zonemaster VAV is a serial bus based system which has a Control bus and Data bus. The Control bus provides 24VAC power for up to 8 Dampers via the main controller as shown in Fig 2. Figure 2. Wiring diagram of Zone 1 to Zone 8 Page 3...
Page 7
The Data bus provides communication between the main controller and the touchpads. NOTE: The Main Controller provides power for up to 8 Touchpads and damper motors. If more than 8 touchpads and dampers are installed auxiliary power must be provided via separate 24VAC and 9VDC power supplies as shown in figure 3. Figure 3. Wiring diagram of Zone 9 to Zone 16 Page 4...
INSTALLATION Remove the 3 covers from the main control board. Position the main controller on top of the fan coil unit or on the supply air duct and secure. Connect the 24VAC power supply to the terminals N + L on the main controller board. When turning on the power, the red LED will illuminate to show that the main controller is ready.

Make sure every touchpad is working correctly by checking the clock and the temperature displayed on the touchpad. Plug a control cable into the ‘VAV’ socket on the main board and the other end into the ‘24Vac IN’ port on a triple adaptor. Plug the triple adaptor into the motorised damper closest to the main board. Warning - Only yellow Polyaire™ Dampers are compatible with the system. Use another control cable to plug into ‘24Vac OUT’ port on the triple adaptor and the other end of the cable to ‘24Vac IN’ port on the other adaptor for the next motorised damper. Follow Step 8) to connect all motorised dampers in series as shown in Figure 2.
Turn off the power and disconnect the touchpad. Position the touchpad at the right place. Ideally, its position should be approximately 1.6 metres off the floor on the wall. Fit the data cable and the control cable through the wall cavity and connect to the touchpad again. 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. Apply the power again to the transformer. The LCD should show clock time and temperature where the touchpad is located after showing ‘initiate’ on the second line for about 15 seconds.
Take off the small cover on the top of the damper controller and set a special address for the bypass damper controller. Use a pre-tested control cable to connect the bypass damper controller to the ‘point’ socket on the main controller board. Make sure the red light on the damper controller is on. Otherwise, check the cable and the connection. COMMISSIONING The Zonemaster VAV system has several parameters that must be set in the commissioning stage. Zone touchpad (3 button) can only set three zone parameters: 1) Touchpad Address 2) Temperature Sensor 3) Minimum Ventilation Master touchpad (6 button) can set the above parameters and three...
2) For zone touchpads, pressing button after the setting of all three parameters will return to the normal operation mode. 3) For the master touchpad, pressing button will return to the normal operation mode. 2. Initialisation of Touchpad Address Each touchpad (zone) must have a unique address from 1 to 16 to be identified by the main controller. The touchpad has a factory default of ‘No addr’ that cannot be identified by the main controller. The touchpad needs to be initiated by allocating a unique address. The allocation can be carried out by pressing or button, and then pushing (zone touchpad) or (master touchpad) button.
2) At the setting mode, press (zone touchpad) or (master touchpad) button until the LCD displays the ‘Sensor’ screen Press button to adjust the displayed value to the recorded value. 4. Minimum Ventilation Customers may prefer minimum ventilation during the climate control. This ventilation allows a minimum airflow into the zone that is switched on. The amount of ventilation can be set from 0 to 30% open with a default of 0%. At the setting mode, press (zone touchpad) or (master touchpad) button until the LCD displays the ‘Min Vent’ screen. Press button to adjust the percent value of the minimum ventilation as desired.
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 safety H-limit and L-limit MUST be disabled by pressing button during the setup. Spill or Bypass Modes A ‘Spill’ or “Bypass” function is designed to relieve pressure in the duct if too many zones have been turned off. Spill Mode The VAV system has an inbuilt “Spill” system that will automatically open vents if too many have inadvertently been closed. The preset factory default is 30% of the total number of zones. The Preset Factory default can be varied but we recommend 30% as the lowest safe value to protect the duct. In Spill mode the zones with the lowest addresses in the system are automatically opened if the total number of open zones is less than the assigned spill setpoint. (IE: If the system has 10 zones numbered 1- 10 and all have been closed the VAV will automatically open zones 1,2, 3 to relieve the pressure. The only way to close these “spill” zones is to make sure at least 3 other zones are open.
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 or button to change the spill/bypass setpoint to its desired value. The adjustable range is from 0% to 50%. We recommend a setting of 30% or more to safeguard Duct. If no spill or bypass control is required in the system, the setpoint MUST be set to 0%. 7. Naming Zones - Master Touchpad The name of a zone is called ‘Zone_addr’. For example, zone 1, which has an address of 1, is called ‘Zone_1’ on its factory default. The names can be customised as follows: 1) At the setting mode, press button until the LCD displays the first zone name, for example ‘Z1 Name’ on the top line of the LCD. The second line shows the current name of zone 1.
