Blocking cooling during winter season
Blocking cooling using the input "HAVC_Mode"
During the winter, it is possible to block the cooling valve at low outside air temperatures to save energy on cooling load.
To select between several options, connect the macro "SWM_SummerWinterMode" and connect the output "HVAC_Mode" to the same input of this macro.
Cooling will be enabled only if the "HVAC_Mode" transmits the values 3 or 4.
Blocking cooling with own parameters for the cooling limit
To use the macros own parameters for the cooling limits, set the value 999 to the input "HVAC_Mode".
With parameter OAT-02 the temperature can be defined, below which the cooling valve will stay closed.
With the HVAC_Mode disabled, the value of parameter OAT-02 will be transmitted to the output "OATLimitCooling" to be connected to the DX cooling macro.
Use the output "OATLimitCooling" only if "HVAC_mode" not used (= 999).
