LA 60P-TUR

3.2 Switch box

The switch box (4) is located on the long side of the heat pump.
The switch box contains the power contactor, the soft starter
unit and the refrigeration circuit control.
CAUTION!
The switch box must be designed to have restricted breathing
in accordance with DIN EN 60079-15. It may only be opened
by authorised and qualified after-sales service technicians in
connection with maintenance or service work. Prior to
commissioning or after the work is complete, a check must be
carried out to determine restricted breathing in accordance
with the repair manual.

3.3 Connection box

The connection box (5) contains the supply connection termi-
nals (load/control voltage) and the connecting terminals for the
communication line.
NOTE
Connection work must only be carried out on the connection
box.

3.4 Heat pump manager

A heat pump manager (controller -N1) must be used for operat-
ing your heat pump.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system based on the outside temperature, as well as domestic
hot water preparation and operating limits.
The external temperature sensor to be mounted on-site is in-
cluded in the heat pump manager scope of supply together
with the necessary fixing accessories.
The functions and usage of the heat pump manager are de-
scribed in the operating instructions (supplied).

Accessories

4.1 Building management system

The heat pump manager can be connected to a building man-
agement system network via supplementation of the relevant
interface plug-in card. The supplementary installation instruc-
tions of the interface card must be consulted regarding the
exact connection and parametrisation of the interface.
The following network connections can be made on the heat
pump manager:
 Modbus
EIB, KNX

Ethernet

4.2 External four-way reversing
valve
The external four-way reversing valve (Y12) enables operation
of the reversible air-to-water heat pump optimised for heating
and cooling. Switching the direction of flow ensures an optimal
flow through the heat exchanger in the heat pump in heating
operation as well as in the opposite direction in cooling opera-
tion. The actuator, driven by an electrical motor and required for
automatic switching, is controlled by the heat pump manager.
(Max. permissible switching current 2A).
The external four-way reversing valve with an actuating time of
max. 30 seconds ensures switching of the water flow over the
complete temperature operating range without any mixing
losses.
The installation of the four-way reversing valve, available as an
accessory, is required to reach the heating and cooling capacity
and coefficient of performance (COP) mentioned in the device
information. The specified operating limits are only fulfilled in
combination with this accessory. A detailed installation descrip-
tion can be found in the instructions included with the valve.
NOTE
For operation of the heat pump with the external four-way
reversing valve, it is essential to set up the hydraulic
connections according to the instructions included with the
valve. These instructions describe the procedure for setting
up the correct hydraulics in more detail. The alternating
direction of flow in the heating and cooling operation is to be
checked as part of commissioning.
The hydraulic diagram in the attachment shows the basic de-
sign.
