4.1 External four-way reversing
valve
The external four-way reversing valve (Y12) enables optimised
heating and cooling operation of the reversible air-to-water
heat pump. 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 circuit diagrams in the attachment show the
basic design.

Transport

CAUTION!
When transporting the heat pump, ensure that it is not tilted
more than 45° (in any direction).
Transport to the final installation location should be carried out
with a pallet. The basic device can be transported with a lift
truck or a crane.
The transport eyebolts must be removed after crane transport,
and the openings must be closed using the vent plugs supplied.
After transportation, the transport fastening in the device is to
be removed from both sides of the base.
CAUTION!
Before start-up, the transport fastening must be removed.
