Support control function maintains room temperature during scheduled "Stop" period.

If during "Stop" hours the room temperature deviates off preset limits - the AHU is started for heating or cooling.


Support control function requires room temperature signal to operate.


It is possible to heat / cool recirculated room air instead of fresh air if the AHU is recirculation capable.

Use of extract air fan can also be enabled if position of the fan placement makes it reasonable.
