Water-to-water heat pump for indoor installation with integrated WPM EconPlus regulation and two compressors for output reduction when operating at partial load. The control panel is integrated into a brown-red design screen and can also be used as wired remote control using the wall mounting set (special accessories MS PGD). Variable connection options for the water and heating connections on the rear wall of the casing. Access for service work from the front, no minimum clearance required on the sides, accessible from underneath with a lift truck. Sound-optimised through insulated metal casing and double vibration-isolated compressor. Integrated solid-borne sound insulation for direct connection to the heating system. High coefficients of performance (COP) thanks to economiser, electronic expansion valve and compliance with the requirements of EN 14511 for larger volume flows on the heat consumption side. Sensor monitoring of the refrigeration circuit for a high degree of operational safety and integrated thermal energy metering (display of the calculated quantity of thermal energy for heating and domestic hot water preparation on the WPM EconPlus heat pump manager). Universal design with flexible expansion options for:

• Bivalent or bivalent-renewable operating mode

• Distribution systems with unmixed and mixed heating circuits

Soft starter, integrated flow and return sensors; external sensor (standard NTC-2) included in the scope of supply.
