Heat pump for heating purposes for outdoor installation, with wall-mounted WPM EconPlus heat pump manager and two compressors for output reduction when operating at partial load. Sound-optimised through the use of two slow-running EC-3D fans, an encapsulated compressor housing and a free-swinging compressor baseplate for solid-borne sound insulation. High coefficients of performance (COP) through high-performance evaporator, electronic expansion valve and compliance with the requirements of EN 14511 for larger volume flows on the heat consumption side. High operational safety through sensor monitoring of the refrigeration circuit for energy-efficient defrosting; integrated thermal energy metering (display of the thermal energy volume for heating and domestic hot water preparation on the WPM EconPlus heat pump manager). Access for service work on the outlet side; the minimum clearances must be observed for installation close to walls. Can be easily transported with a lift truck (accessible from underneath) or lifting lugs. Universal design with two compressors for modulating operation, optional domestic hot water preparation and flexible expansion options for:

• Bivalent or bivalent-renewable operating mode

• Distribution systems with unmixed and mixed heating circuits

At an external temperature of -10 °C, the maximum flow temperature that can be achieved is 60 °C. Soft starter, integrated flow and return sensors; external sensor (standard NTC-2) included in the scope of supply. Electrical connection cable EVL ..UE between heat pump and heat pump manager must be ordered separately.
