Settings status and change
Select from service status and settings status.
• If the user interface is unlocked and the button to show
display options is pressed for 2–10 seconds the user interface
will switch to settings mode.
– The settings can be changed when they are shown.
– The settings are shown in a specific order.
• When the button is released the user interface returns to
service status and the last saved setting.
• See diagram for status and change of settings.

OPERATING PRINCIPLES
NOTE:
All the circuit diagrams (with the exception of the first)
include a buffer tank, because this is normally used for a
better temperature balance between the heat pump and the
heating/cooling system. The sensors are therefore placed in
the buffer tank. If the system does not have a buffer tank the
sensors must be placed directly on the water pipes. Place the
sensors on copper pipes or the equivalent for best temperature
registering.
•
All the sensors are placed on the indoor unit. Adjust the
positions of the sensors to the actual application.
•
All sensors (T1, T2 and T3) must be connected to the circuit
board, even if they are not used in the actual application,
to avoid error codes being shown.
•
Make sure to insulate pipes and sensors if the sensors are
mounted directly on the water pipes.
ROOM HEATING APPLICATION 1
• In this application the heat pump is connected to the
heating system’s return pipe. The heat pump can be
regulated according to a fixed or variable water temperature
(curve, based on outside temperature). Choose between the
15 preset curves according to the instructions. The curves can
be adjusted manually.
• This heat pump has no internal auxiliary heater and
therefore an existing heat source, such an an oil boiler,
must be connected as a reserve heat source. The installation
also requires that the reserve heat source has a functioning
control unit, which controls the supply temperature to the
heating system. When the heating requirement exceeds the
capacity of the heat pump, the reserve heat source starts
automatically and supplies additional heat. The heat pump
curve or the set point temperature for the heat pump should
therefore be set somewhat higher than the corresponding
values for the control unit for the existing heat source.
This means that the heat pump is always used in the first
instance.
• There must always be a by-pass between the heat pump’s
inlet and return pipes, fitted with a ball valve. This by-pass
can consist of the actual return pipe. See installation
drawing.
• All sensors (T1, T2 and T3) must be connected to the circuit
board, even if they are not used in the actual application.
Place the water temperature sensor on the return pipe if the
system does not have a buffer tank. Make sure that sensors
are in good contact with the pipe, and insulate pipes and
sensors.

FIG. 15
1. Place the sensor T2 (heating) in the sensor holder in the top
part of the buffer tank.
2. Place the sensor T3 (cooling) in the sensor holder in the
bottom part of the buffer tank.
– If the system does not have a buffer tank the sensors T2
and T3 must be placed directly on the water pipes.
– For more stable operation of the heat pump it is
recommended to place the sensors on the return pipe
and that the heating curve or cooling temperature is
adjusted to the normal delta T for the heating/cooling
system.
– The heat pump’s set point temperature is regulated
from the actual positioning of its sensors.
ROOM HEATING/COOLING APPLICATION 3
+ TAP WATER
NOTE:
•
In this application a reversing valve (accessory) is required
to switch the direction of flow according to the set point
temperature for heating/cooling and the hot tap water.
•
Never mix water from the heating/cooling system with
hot tap water.
