LAK 3IMR - LAK 14ITR
2 Purpose
2.1 Area of application
The indoor unit constitutes the interface between a reversible
heat pump and the heating system in the building. The indoor
unit contains all hydraulic components required between heat
generation and heat distribution with an unmixed heating circuit.
2.2 General properties
 Low installation effort
 Ready for use
 The infinitely adjustable operation of the circulating pump
permits adjustment of the output according to need.
on LAK 6IMR - LAK 14ITR:
 Switchable pipe heater (2 / 4 / 6 kW) for supplementary heat-
ing.
on LAK 3IMR:
 with 2 kW (fixed-setpoint) pipe heating

3.2 Contact plate
The cover must be removed to allow access to the inside of the
device.
The two screws on the bottom must be loosened for this. The
cover must then be removed to the top.
ATTENTION!
Before opening the device, ensure that all circuits are disconnected from
the power supply!
After removing the cover, the electronics area is freely accessi-
ble.
The contact plate contains the supply connection terminals, heat-
ing contactors, connecting terminals for the connecting line to the
heat pump and the heat pump manager.
3.3 Wärmepumpenmanager
The integrated heat pump manager is a convenient electronic
regulating and control device. It controls and monitors the entire
heating system based on the outdoor temperature, as well as do-
mestic hot water preparation and safety systems.
The enclosed operating instructions describe the functional prin-
ciple and use of the heat pump manager.
