Max. flow temperature for heating 55 °C
Casing colour white
Water-to-water heat pump
with stainless steel coil heat exchanger
WI 9-27TE
Heat pump for indoor installation with integrated regulation WPM 2007 plus. 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 rear wall of the casing. Sound-optimised through insulated metal casing
and double vibration-isolated compressor. Economiser for high coefficients of performance. Integrated corrosion-proof and freeze-proof
stainless steel coil heat exchanger. Universal design with optional DHW preparation and the option of flexible expansion 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 flow sensor,
external sensor (standard NTC-2) and dirt filter for ground water included in the scope of supply.
Lower operating limit heat source (heating operation) 7 °C ; Upper operating limit heat source (heating operation) 25 °C ; Refrigerant
R407C ; Connection heating 1¼ ⬙ ; Heat source connection 1¼ ⬙.

Important information for coil heat exchangers:
at water t
emperatures below 13 °C, no water analysis with regard to corrosion is necessary.
Note for heat source systems:
If the limits for iron (Fe up to 0. 2 mg/l) or manganese (Mn up to 0. 1 mg/l) there is danger of ochre sedimentation of the heat source system.
This is also true for coil heat exchangers.

High-efficiency water-to-water heat pumps
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 rear wall 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 COPs
through 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 refrigerating circuit for high degree of operational safety; integrated thermal energy
metering (display of the calculated thermal energy volume 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 con-
trol 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 the option of flexible expansion for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Integrated soft starter, flow and return-flow 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)!
