    Introduction This manual explains the function, control parameters and fault messages of the WPR 300 heat pump control unit for Viessmann heat pumps. With the control parameters, the heat pump can be matched to varying demands and operating conditions. To avoid incorrect operation of the heat pump or other system components, the control parameters and fault messages are available at three different setting levels.
