Min ow at cool output when control mode Heating/Cooling with VAV- control is selected
20%
Min ow at Y3 output when control mode Heating/Cooling/VAV is selected
49 Max ow on Y3 output when control mode Heating/Cooling/VAV is selected and in heating mode 0%
50
Conguration of fan control:
3
0=No control
1=Fan is controlled by heating demand
2=Fan is controlled by cooling demand
3=Fan is controlled by both heating and cooling demand
