Solarbayer Inverter Heat Pump LWM12-3P Air-to-water heat pump 12kW R32/400V

The Solarbayer air-to-water heat pump
LWM 12 (12kW / 400V) is a compact all-in-one
device for outdoor installation. The system
controller with capacitive touch operation
enables monoenergetic and bivalent operation
with an individually adjustable bivalence
point for requesting an additional heat
generator (e.g. oil/gas heating). Equipped
with high-efficiency pump and fully hermetic
inverter-controlled scroll compressor. All
hydraulic components such as circulation pump,
external expansion vessel, safety and vent
valve, flow sensor as well as an integrated
backup heater and condensate tray heater are
fitted as standard. The refrigerant circuit
is fully integrated into the outdoor unit so
that no additional refrigerant pipes are
required. This solution is compact, easy to
install and saves space inside the building.

Further features:
- Integrated WiFi module enables remote
access and control via APP
- Energy efficiency display: Integration of
an energy efficiency display
via the app to make energy consumption
transparent and comprehensible
comprehensible
- Weather-compensated operation: Variable
flow temperature through a 3-way
mixing valve and an electro
thermal actuator possible
- Single-circuit solar differential control
- Cascade operation possible
- Smart Grid interface (SG Ready)
for the utilisation of regenerative
surplus electricity to increase the
setpoint to 55°C* in hot water mode
(*increase to max. 70° possible with
optional heating element in the cylinder)
