Blocking heating during summer season

Blocking heating using the input "HAVC_Mode"

During summer, it is possible to block the heater valve at high outside air temperatures to save energy on heating load.

To select between several options, connect the macro "SWM_SummerWinterMode" and connect the output "HVAC_Mode" to the same input of this macro.

Heating will be enabled only if the "HVAC_Mode" transmits the values 2 or 4.

Note: The "HeatCtrlSig" output signal will be automatically released again; if the coded signal "HumidityMode" equals the value of "2" (dehumidification is needed).


Blocking heating with own parameters for the heating limit

To use the macros own parameters for the heating limits, set the value 999 to the input "HVAC_Mode"

With parameter OAT-01 the temperature can be defined, above which the heater valve will stay closed.


Note: The "HeatCtrlSig" output signal will be automatically released again; if the coded signal "HumidityMode" equals the value of "2" (dehumidification is needed).
