Will be active only when fan is on (G terminal) and the internal or

remote scheduling is in occupied mode.

When internal or remote scheduling is in unoccupied mode and/

or fan is off, minimum position will be set to 0%

mode.

Allows the operation of the mechanical cooling if the free cooling

(economizer) cannot maintain the cooling setpoint.

Off Typically applies when the MS (mixed air temperature

sensor) is installed after the mechanical cooling refrigeration

coils. In this case, mechanical cooling will never operate at the

same time as free cooling.

On Typically applies when the MS (mixed air temperature

sensor) is installed before the mechanical cooling refrigeration

coils in the mixing plenum. In this case, mechanical cooling is

allowed when the free cooling (economizer operation) cannot

maintain the cooling setpoint.
