Caution The room setpoint shift to for an HVAC group is effected via a VIP point. For each @TCGm HVAC group the CFE software automatically generates an
associated @VIPm. Values written to this point are passed on to the @TCRn.RRSC parameters of all group members.
Note The value x of RRSC is mapped as follows:
x > 0 : occupied_heat = x, occupied_cool = 0
x < 0 : occupied_heat = x, occupied_cool = x
In both cases, the setpoints in the controller are shifted in parallel in this process.
