9) Check all the LED lights on the damper controllers again.
 Ifsomeofthelightsareoff,thecabletotherst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.
11) 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ashinginone-second  
interval. Otherwise, check the cable and the connection.
12) Turn off the power and disconnect the touchpad.
13) Position the touchpad at the right place. Ideally, its position
 isapproximate1.6Mofftheooronthewall.Fitthecable  
through the wall cavity and connect the touchpad again.
14) Apply the power again to the transformer. The LCD should
show clock time and temperature. If not, check the cable.
15) Mount the supply air sensor in the supply air duct upstream the
motorised damper.
16) Fit the sensor cable through the

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identiedbythetouchpad.Thisaddressiscongured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rst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satised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.

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.
3. Number of Zones in the System
For the purpose of zone status display and spill/bypass zone
calculation, the controller needs to know the total number of
on/off zones in the system. Its factory default value is 8.
1) At the setting mode, press button until the
LCD displays the ‘O/FZone’ screen.
2) Press or button to adjust the number
of zones to the total number of the zones installed.
It can be selected from 1(show ‘Zone1’) to 8
(show ‘Z1—Z8’).

Page 11
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 60oC 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.
5. Spill/Bypass Air Setpoint
Spill/Bypass air is primarily used to relieve duct pressure for the safety
of the ducting. Such a control is achieved by comparing the system
requirement with a setpoint. The factory default is in spill mode and the
setpoint is 30% of the total number of zones, which is equivalent to 30% of
thetotalairowacrossthefancoil.

Page 12
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 13
6.NamingZones
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 you prefer as follows:
1) At setting mode, press button until the
     LCDdisplaystherstzonenaming,forexample, 
‘Z1 Name’ on the top line of the LCD. The second
line shows the current name of zone 1.
2) Press or button to select one of the
27 preset zone names for the zone.
3) To make changes to the preset selected name,
press button to move to the character that
     isashing.
4) Use or button to select the character
from the list as desired. There are 26 alphabets
in capital and normal case, 10 numbers and a
space in the list.
5) Press button to select the next zone
naming screen and follow steps 2 to 4 to
customise the name of the zone.
7. Damper on/off Test
1) Switch on the air conditioner.
2) Press button to turn each of the zones on or off to
check if the damper is correctly connected by feeling the air
at the outlet. Refer to User’s manual for the operation.
