Heat pump for heating purposes - water as heat source
Max. flow temperature 58 °C
Casing colour White (similar to RAL 9003)
High-efficiency water-to-water heat pump
With two performance levels
WI 50TU
WI 100TU
Water-to-water heat pump for indoor installation with integrated WPM EconPlus regulation and two compressors for output reduction
when operating at partial load. Variable connection options for the water and heating connections on the back board of the casing.
Access for service work from the front, no minimum clearances required on the sides. 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). If the evaporation temperatures are too low (e. g. water flow too low) the heat
pump switches off; no flow rate switch is necessary. A flow rate switch (available as a special accessory) can be installed for well systems
with an uncertain water supply. 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). 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.

A water-to-water heat pump must be used if borehole heat exchangers are used which work using water as the heat transfer medium.
A ground water analysis for the copper-soldered stainless steel heat exchanger is mandatory (see the project planning documentation)!

WI 18-27TE
Heat pump for heating purposes for indoor installation with integrated WPM 2007 plus controller. 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 ground water and heating connections on the back board of the casing. Sound-optimised through
insulated metal casing and double vibration-isolated compressor. Economiser for high coefficients of performance (COP). Integrated
corrosion-proof and freeze-proof stainless steel coil evaporator. Universal design with optional domestic hot water preparation and
flexible expansion possibilities for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Integrated soft starter (from WI 14), integrated flow rate switch and load contactor for a well water pump; flow sensor, return sensor,
external sensor (standard NTC-2) and dirt filter for ground water included in the scope of supply.

Important information concerning coil heat exchangers:
at water temperatures below 13 °C, no water analysis with regard to corrosion is necessary.
Note on the heat source systems:
if the limits for iron (Fe up to 0.2 mg/l) or manganese (Mn up to 0.1 mg/l) are exceeded, there is danger of ochre formation in the heat source
system. This is also true for coil heat exchangers.
