Connection to the Macro “SWM_SummerWinterMode"

The “HVAC_Mode“ input signal of “PRCH_PreCtrlHtg” must be connected to the “HVAC_Mode“ output of the macro “SWM_SummerWinterMode“.

The outside air temperature limits for heating and cooling are defined in “the “SWM_SummerWinterMode“ macro and transmitted via the output “HVAC_Mode“.

This macro offers several possibilities to set the HVAC_Mode:


The "HVAC_Mode" from the “SWM_SummerWinterMode” can transmit four values: 1 = off; 2 = heat; 3 = cool; 4 = auto, depending on the parameters for heating and cooling limits.

The next figures show the states of the "HVAC_Mode" with non-overlapping and overlapping values of the outdoor temperature limits.
