High-efficiency water-to-water heat pump.
Heat pump for heating purposes for indoor installation with integrated WPM Econ5Plus control. Variable connection options for the ground water and heating connections on the rear wall of the casing. Integrated solid-borne sound insulation for direct connection to the heating system. Sound-optimised through encapsulated compressor housing and free-swinging compressor baseplate. High coefficients of performance (COPs) thanks to electronic expansion valve, COP booster and compliance with the requirements of EN 14511 for larger volume flows on the heat consumption side. Integrated corrosion-proof and freeze-proof stainless steel coil evaporator. 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 Econ5Plus heat pump manager). If the evaporation temperatures are too low, e.g. due to an inadequate water flow, the heat pump switches off, which means that no flow rate switch is required. For well systems with an insecure water supply, a flow rate switch available as a special accessory can also be installed. The control panel is integrated in a design screen and can also be used as wired remote control using the wall mounting set (special accessories MS PGD). Universal design with flexible expansion options for:
– Room temperature control via Smart RTC (special accessory)
– Bivalent or bivalent-renewable operating mode
– Distribution systems with unmixed and mixed heating circuits
– Use of load-variable tariffs (SG Ready)
Integrated soft starter (from WI 14); integrated load contactor for well water pump; flow sensor, return sensor, external sensor (standard NTC-2) and dirt filter for ground water included in the scope of supply.
