TART UP
Commissioning the system before initial start up
CAUTION
Besides the checks before initial start up of the indoor unit
(refer to the installation manual of the indoor unit) you must
check the following items on the solar kit installation before
switching on the circuit breaker:
The domestic hot water tank is filled with water. Refer
to the installation manual of the domestic hot water
tank.
The circuit, connected to the solar kit is filled with
water. Refer to the installation manual of the indoor
unit.
The solar collector circuit is filled with glycol. Refer to
the installation manual of the solar circuit.
Make sure the solar kit is properly fixed to the
domestic hot water tank and that there are no leaks.
Ensure the power supply cable from the indoor unit is
connected to the domestic hot water tank.
Mounting of sensors
Make sure the solar panel temperature sensor and
the domestic hot water temperature sensor of the
solar pump station are properly mounted.
Ensure that the auxiliary contact of the solar pump
station is connected to the indoor unit and will give to
the input of the indoor unit when the pump of the solar
pump station operates.
WARNING
Field wiring and earthing
Make sure the pump of the solar kit is connected to the
domestic hot water tank as shown in the wiring diagram
and the pump earth wires have been connected properly.
The earth terminals should be tightened.
CAUTION
Verify that following settings are made on the solar pump
station:
Maximum solar panel temperature: ≤212°F (100°C)
Maximum tank temperature: 176°F (80°C)
Minimum temperature difference between domestic
hot water tank and solar panel before starting pump
operation: ≥18°F (≥10°C)
NOTE
Make sure a non-return valve is included in the solar
pump station or is installed in the connection line from
the solar pump station to the solar kit. Refer also to the
general system set-up (on
Absence of this valve will cause thermal losses and
could cause freezing of the plate heat exchanger.
Checklist for proper functioning
Following items should be checked to assure proper functioning:
When the temperature of the solar panel becomes 18°F (10°C)
higher than the domestic hot water tank temperature, the pump
of the solar pump station and the pump of the solar kit will start
(1)
operation.
When the temperature of the solar panel becomes lower than
the domestic hot water tank temperature, the pump of the solar
pump station and the pump of the solar kit will stop operation.
(1) Unless the domestic water heating mode is enabled, the solar priority parameter
= 1 and the heat pump is heating the domestic water tank at that moment.

for more information.
Final check
Before switching on the unit, read following recommendations:
When the complete installation and all necessary settings have
been carried out, close all front panels of the unit and refit the
indoor unit cover.
The service panel of the switch box may only be opened by a
licensed electrician for maintenance purposes.

PERATING INSTRUCTIONS
Configuring your system
In order to guarantee maximum energy savings combined with
maximum comfort, it is important to configure your system in a proper
way.
For this reason, it is strongly recommended to do the following:
Use of schedule timers
Check the orientation of your solar panel, and find out during
what time of the day the intensity of the sun on it is expected to
be strong and weak. For example, a solar panel oriented to the
east will receive strong intensity during the morning, weak
intensity during the afternoon.
Check your usual pattern of peak domestic hot water
consumption. E.g. showering during the morning from 7 to 9
a.m. and again in the evening from 5 p.m. onwards.
Set the schedule timer for 'domestic water heating' and 'booster
heating' as to disable heating of the domestic water tank by the
indoor unit before solar radiation on the solar panel can become
intensive.
On the other hand, enable 'domestic water heating' and/or
'booster heating' about 1 hour before you usually expect
domestic hot water consumption or during night time. In this way,
the indoor unit and/or booster heater will heat up the domestic
water tank and guarantee domestic hot water in the event there
has been no sun.
