Heating heat pump for indoor installation with integrated WPM EconPlus control. Variable connection options for the groundwater and heating connections on the rear wall of the housing. Integrated structure-borne sound decoupling for direct connection to the heating system. Sound-optimized by encapsulated compressor chamber and freely swinging compressor base plate. High performance figures thanks to electronic expansion valve, COP booster and compliance with the requirements of EN 14511 for larger volume flows on the heat utilization side. A stainless steel spiral evaporator optimized against corrosion and freezing is installed. Sensory monitoring of the cooling circuit for high operational reliability and integrated heat quantity metering (display of the calculated heat quantity for heating and hot water preparation on the WPM EconPlus heat pump manager). If the evaporation temperature is too low, e.g. due to too little water throughput, the heat pump switches off so that no flow switch is required. In well systems with an unreliable water supply, a flow switch available as a special accessory can also be installed. The control unit, which is integrated into a brown-red design panel, can also be used as a wired remote control using the wall mounting set (special accessory MS PGD). Universal design with flexible expansion options for: bivalent or bivalent regenerative operation distribution systems with unmixed and mixed heating circuits soft starter (from WI 14), load contactor for well water pump integrated, flow sensor, return sensor, external sensor (standard NTC-2) and dirt filter for groundwater included in delivery.
