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+ offers the flexibility of balancing the
amount of airflow 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. Confirm the required value to start the balancing process. All zones
will open to its balanced position. You can input proper value and check the
airflow on the fly 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 flow adjustment to the groups. The overall opening % of the
zone is calculated as %OPEN x Balance %.
