Operation Instruction for Air condition unit with the
VAV SYSTEM system
The Air condition handheld remote control with the I/R receiver allows the
operation of the system.
The overall system can be operated in the following mode of operations:
‹‹ Cool – Set the temperature set point at the Air Condition handheld remote
control to be same as the temperature required at the rooms.
‹‹ Heat - Set the temperature set point at the Air Condition handheld remote
control to be same as the temperature required at the rooms.
‹‹ Fan Only (Ventilation) – The Zone Control system will act same as at Cool
mode.
‹‹ Dry - The Zone Control system will act same as at Cool mode.
‹‹ Auto – Do not use this mode of operation.
‹‹ In case Auto mode is selected, the zone control system will open all
dampers to full open position except the rooms which are OFF. The zone
control is not operated at the rooms.
‹‹ When the system is not in use, turn OFF all handheld remote controls at
each room.
Note: When the system automatically changes the fan speed to Low speed, a
beep will be sound. This Beep sound is normal as the system gives indication
for reducing speed for balancing the air flow in the ducts.
