11.8 Operation without the collector and
operating during construction
The heat pump can be used for heating before the collector
is connected. All of the heat will be generated by the heat
pump’s electric heater using electricity. However, all of
the control functions for heating and domestic hot water
are available. Note that the heating and domestic hot water
circuits should be connected and vented, and that the
electrical connections should be completely ready for use.
If the heat pump is to be used for heating during
construction, the device should be set to “Emergency
operation” mode to ensure that the compressor (K1) and
the source pump (Q8) do not start up. This ensures that the
heat pump uses the electric heater (SV1) for domestic hot
water and heating.
11.9 Purging the collector
The collector must be purged of air with extreme care.
If there is even a small amount of air in the collector,
the device will not operate optimally and may
malfunction.
Purging the charge and collector

Put the line protection switch for the charge and
pumps (Q9 and Q8) into the “ON” position.

The controller’s line protection switch (F10)
should be in the “OFF” position.

Allow the pumps to operate for a moment, and
then turn them off.

The air will begin moving and it will escape from
the air vents. If necessary, open the air venting
valves.

Check that the charge and collector has a
pressure of 1–1.5 bar.

Repeat this procedure until the circuits make no
trickling/bubbling sounds, or other noises
indicating the presence of air.
12 HEAT PUMP SETTINGS
All heat pump settings should be entered primarily using
the app. These instructions include the settings in the
event that the app is not working or is unavailable for other
reasons.
Some of the settings can only be configured at the expert
level. If you are unable to access a setting, press the roller
for 3 seconds and set the code 2000.
12.1 HEAT PUMP
Time and date
The regulator has an annual schedule with the time of day,
day of the week and date. To ensure that the heating
programme functions correctly, the time and date must be
set correctly. The heat pump will not start up until the time
and date have been set.
The time can be set on the controller menu by selecting
MAIN MENU > HEAT PUMP.
Language selection
By default, the heat pump’s language is Finnish. Several
language options are available for the user terminal. You
can change the language by selecting MAIN MENU >
HEAT PUMP
Language options
English, Swedish, Finnish
Operating mode HMI
The heat pump is activated and deactivated with the
OPERATING MODE HMI
setting. When delivered with
factory settings, the setting is on
OFF
-mode. By
switching the setting to
AUTO
-mode, the
heat pump activates. The heat pump activates
automatically and starts to heat domestic hot water and
heating circuit according to heating demand.

12.2 DOMESTIC HOT WATER
The heat pump’s automatic regulation prepares domestic
hot water based on the tank measurements. The automated
process has a switching difference, which is used to start
and stop the charge. There are two domestic hot water
temperature sensors: one in the upper part of the tank,
reading the domestic hot water temperature, and the other
in the lower part of the tank, used to control the charge.
The domestic hot water set point can be adjusted in the
DOMESTIC HOT WATER menu. The set value and the
connection difference affect the functional sub sensor
(B3).
