Proportional temperature control in HEAT mode (HEAT PUMP)
The compressor is controlled by an analogue input and by the Heating setpoint.
Heating setpoint: this is the reference setpoint when the device works in heat mode.
N.B.: temperature control is enabled in HEAT mode only if: tr01 (enable heat pump) = 1 (heat pump present)
See also Block Heat Pump
Probe AIn used in temperature control can be selected in parameter tr03:
N.B: Always set tr13> tr11
Power power
*Step 1 Step 1
*Step 2 Step 2
*Only for machines with two compressors or partialized compressor.
AIn temp.
temperature read by the probe selected for temperature control in Heat.
