Heat pump for heating purposes - ground as heat source
High-efficiency brine-to-water heat pump
Max. flow temperature 62 °C
Casing colour White (similar to RAL 9003)
High-efficiency brine-to-water heat pump
Universal design with solid-borne sound insulation
SI 11TU
Heat pump for heating purposes for indoor installation with integrated WPM EconPlus. Variable connection options for brine and hea-
ting connections on the back board 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. 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). 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 optional domestic hot water preparation and
flexible expansion possibilities 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.
High-efficiency brine package with electronic control of the brine pump and the brine circuit manifold must be ordered separately.

Supporting feet for high-efficiency brine-to-water heat pump
STF 4
Supporting feet for fitting to the brine-to-water heat pumps and the water-to-water heat pumps in the TU series. The supporting feet are
fitted to the bottom of the heat pump, enabling it to be installed level, even if the floor is uneven. Scope of supply: 4 units.

Universal design
SI 22TU
Heat pump for heating purposes for indoor installation with integrated WPM EconPlus. Variable connection options for brine and hea-
ting connections on the back board of the casing. Integrated solid-borne sound insulation for direct connection to the heating system.
Sound-optimised through insulated metal casing and double vibration-isolated compressor. High coefficients of performance (COP) with
economiser and compliance with the requirements of EN 14511 for larger volume flows on the heat consumption side. Sensor monito-
ring 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). 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 optional domestic hot water preparation and flexible expansion possibilities for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Soft starter, load contactor for brine circulating pump, integrated flow and return sensor; external sensor (standard NTC-2) and dirt filter
for brine circuit included in the scope of supply.
Brine package and brine circuit manifold must be ordered separately.
