3. Pre-Installation
Good planning leads to a successful zone system installation. Before installing and
commissioning a zoning system, please complete the following listed tasks:
3.1 Decide how many zones (dampers) are to be controlled in the system.
3.2 Group zones according to customer’s requirements. Each group initially has
one zone but can have up to a maximum of four zones (Example: There
could be one or more zones going into a common area such as Kitchen/
Dining or Family/Dining room). Work out the total group number (Maximum
total group number in a system is 16).
NOTE: It is important to test all cables before installation.
Testing all cables to be used before the start of the installation will save
considerable diagnostic time if the fully installed system is subsequently found
to have a problem. Cable testing is quick and easy with a Zonemaster Cable
tester available from Polyaire.

4.1 Mount the main and/or extension
modules (if using more than 8 zones) by
screwing the boxes to a roof frame or
Polyaire Diusion Fitting (PDF).
Do not place the modules on top of
the indoor unit. The high temperature
between the roof and the indoor unit
can damage the electronic components
over time.
4.2 Remove the two side covers on the
main module. All LEDs and sockets for
zone dampers are exposed.
4.3 If the extension module is used,
connect main module to extension
module at ‘E/M’ port on both modules
with a left latched cable.

It’s not ticked by default.
5.1.1 Total Groups in the System
For the purpose of group status display and spill zone calculation, the system
needs to know the total number of groups to be installed. The factory default
number is 8.
IMPORTANT: This number must be equal to the total group number used in the
system as planned in Pre-Installation process. If this is wrong, the system may
not work properly.

5.1.4 Damper RPM Setting
AirTouch 2+ can work with other dampers which are not made by Polyaire.
But the damper motors have to meet certain requirements:
Power supply: 24 VAC
Drive Open and Drive Close
Revolution per Minute (RPM): 0.1 to 2.5
5.1.5 Touchpad Temp
Touchpad has a temperature sensor which can be used for AC control in some
cases. When the screen is on, it will generate a fair bit of heat and the temperature
sensor value may be higher than the room temperature. When the screen goes
to sleep mode for a while, its temperature value may be close to real room
temperature. If the screen stays untouched most of the time, it may be used for
AC control. Otherwise it’s not recommended to be used for AC control.
In extremely rare cases, the temperature value might need calibration.
If necessary, do it when the screen is not heated up and use an accurate reference
temperature gauge. Input the correct value to match the reference gauge.
If there are two consoles connected in the system, they will be automatically
identied as touchpad 1 and 2.
5.1.6 Reset and Save current system settings
To record all system settings to the console, press Save Settings button.
If the main module has been replaced, the system can be recovered from this le.
Press the Recover Saved Settings button to recover. After successful recovery, the
system has to be powered o for at least 30 seconds and then powered back on
to use the recovered settings.
If the system needs to be reset to factory default settings in some cases, press
Reset to Factory. All group names and settings will be back to original factory
settings.
5.1.7 Supply Air Sensors
Up to four supply air sensors can be used in AirTouch 2+. They can be used for
helping identify the actual mode of the AC unit when it’s set to Auto mode. Or they
will be needed for the ducted systems without a gateway.

5.2 Zone Setting
A zone can be marked as Disabled if the port is faulty or not to be used. Then it will
not be used by any group. The group used this zone before can choose another
good zone. This is useful in the situation where there are 2 ducted systems with an
extension module. The main module is for the zones in one AC and the extension
module is for the zone in another.
Electronic balancing feature of AirTouch 2+ oers the exibility of balancing the
amount of airow to each zone electronically. Once the opening position of the
damper is set, the damper will only open to this position. The default setting for
each damper is 100% opening position and the adjustable range is between 5%
and 100% with 5% increment. The zone settings can be conducted on the touch
screen as below.
a) On ‘Installers’ screen, touch Zones menu
b) Touching the percentage value for the zone to bring up the value input
dialog. Conrm the required value to start the balancing process. All zones
will open to its balanced position. You can input proper value and check the
airow on the y till right value reaches.
c) Repeat the process for all zones which need balancing. Then touch the Stop
button to stop the balancing process.
d) Mark the zone as Disabled if the zone port is faulty or not used.
NOTE:
• The %OPEN value on the Zoning screen can be operated by the user for
additional air ow adjustment to the groups. The overall opening % of the
zone is calculated as %OPEN x Balance %.

For ease of control operation, multiple zones can be grouped together.
The grouped zones are treated as one group with its own name and turned on
or o together. Individual balanced damper position is not aected by grouping,
which means zone balancing can be conducted before or after grouping.
Grouping can be carried out as follows:
a) In ‘Installers’ screen, touch Grouping to enter ‘Grouping’ screen.
5.3 Grouping Zones
b) Then touch + or - button to add or minus zones to the group
c) Repeat steps b) and c) to dene all groups
d) Press the Reset button if the grouping is corrupted.
e) Touch the zones button will show all zone assignments and you can
choose the zones for a group.
Grouping Zones
Note: If a zone is marked as Disabled, it cannot be used in a group,
a good and available zone can be chosen instead.
