INSTALLATION & MAINTENANCE MANUAL
(2) Zone Activation
Zone activation is required to set the number of zone that will be used, and to activate the
respective zone motor terminals on the zone interface box.
NOTE:
•
When "common zone setup" has been set but "zone activation" has not been set, " " is
displayed for other setting items after "Zone Labeling".
(3) Zone Labeling
Personalise each zone and link the available sensors to suit the installation layout and usage.
(4) Nominate Spill Zone(s)
Nominate which zone(s) to be spill zone(s). If common zone is not available, at least one spill
zone should be nominated. Spill zone1-3 should be set to different zones.
(5) Sensor Assignment
Assign the temperature sensors to each zone for better zone room temperature control. One zone
needs to be assigned at least one sensor or thermostat. Multiple sensors can be assigned to the
same zone.
(6) Airflow
Set the designed airflow of each enabled zone and common zone (if available).
(7) Minimum Airflow Ratio
Set the minimum airflow ratio of Indoor Unit. The ratio is specified in this manual "2.4 Compatible
Air Conditioning Unit".
(8) Damper Timing
Set the time of the damper from fully open to fully close. The supported setting range is from 6
seconds to 150 seconds. All damper timings must be the same.
To calculate damper timing from damper RPM (revolutions per minute), damper timing = 0.25 × (60
seconds / RPM). For example, if the damper motor RPM is 1, then damper timing = 0.25 x (60 secs
/ 1 RPM) = 15 seconds. However, we strongly suggest to verify the actual timing in field test.
