1592015300 User manual iCHILL 200 L GB r1.3 09/09/2005 The count-down to the defrost cycle starts when the temperature/pressure of the probe, configured as condensing/evaporating circuit 1 or 2 probe, is lower than dF02 parameter. After the dF09 counting the instruments checks the temperature probe value (configured as combined defrost circuit 1 or 2) and if it is lower than dF10 (temperature setpoint to start the defrost of the circuit1) or dF12 (temperature setpoint to start the defrost of the circuit2) the defrost cycle starts otherwise the unit still runs in heat pump mode.
