Minimum supply air temperature setpoint shift

A DX cooler reacts very fast. It can happen that after short time after it switches on, the supply air temperature in the supply duct is lower than the minimum supply air temperature setpoint. In this case the strategy will reduce the cooling signal switching the DX cooler off. This often leads to a cycling of the DX cooler, but the room temperature is not really cooled down.

Therefore the DX cooler can optionally reduce the minimum supply air temperature setpoint SAT-01. The DX cooler transmits this signal to the air handling strategy input "MinSAT_SpShift".
