CO 15
Operative mode of the evaporator pump / supply fan
0= Not enabled (evaporator pump or supply fan).
1= ON/OFF: continuous operation type 1
When the unit is running in Chiller or Heat Pump the pump or the supply fan is
running. In std-by or remote OFF mode, the pump is OFF.
2= ON/OFF: on if called by compressor
When a compressor is running, the pump or the supply fan is running.
3= ON/OFF: continuous operation type 2
When the unit is running in Chiller or Heat Pump or in STD-By or in OFF, the
pump or the supply fan is running.
4= Modulation: continuous operation type 1
When the unit is running in Chiller or Heat Pump the pump or the supply fan is
running. In std-by or remote OFF mode, the pump is OFF.
5= Modulation: on if called by compressor
When a compressor is running, the pump or the supply fan is running.
6= Modulation: continuous operation type 2
When the unit is running in Chiller or Heat Pump or in STD-By or in OFF, the
pump or the supply fan is running.
