5. MAINTENANCE
5.1. Maintenance activities
In order to ensure optimal operation of the unit, a number of checks
and inspections should be carried out on the unit ar regular intervals,
preferably yearly. This maintenance shall be carried out by the
installer or service agent. Refer to the installation manual for more
details.
The only maintenance which may be required by the operator is:
■ keeping the remote controller clean by means of a soft damp
cloth,
■ checking if the water pressure indicated on the manometer is
above 1 bar.
5.2. Important information regarding the refrigerant
used
This product contains fluorinated greenhouse gases. Do not vent
gases into the atmosphere.
Refrigerant type: R134a
GWP
(1)
value: 1430
Refrigerant type: R410A
GWP
(1)
value: 2087.5
(1)
GWP = global warming potential
Periodical inspections for refrigerant leaks may be required
depending on the applicable legislation. Please contat your installer
for more information.
6. TROUBLESHOOTING
This section provides useful information for diagnosing and
correcting certain problems which may occur with the unit.
7. DISPOSAL REQUIREMENTS
Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with the applicable legislation.
Your product is marked with this symbol. This means that
electrical and electronic products shall not be mixed with
unsorted household waste.
Do not try to dismantle the system yourself: the dismantling of the
system, treatment of the refrigerant, of oil and other parts must be
done by a qualified installer in accordance with the applicable
legislation.
Units must be treated at a specialized treatment facility for re-use,
recycling and recovery. By ensuring this product is disposed off
correctly, you will help to prevent potential negative consequences for
the environment and human health. Please contact the installer or
local authority for more information.
If the supply cord is damaged, it must be replaced by the
manufacturer, its agent or similar qualified persons in order
to avoid hazards.
During longer periods of standstill, e.g. during summer with
a heating only application, it is very important NOT TO
SWITCH OFF THE POWER SUPPLY towards the unit.
Switching off the power supply stops the automatic
repetitive movement of the pump in order to prevent it from
getting jammed.
POSSIBLE CAUSES CORRECTIVE ACTIONS
No readings on the remote controller
(blank display)
• Check if the mains power is still
connected to your installation.
• The benefit kWh rate power
supply is active (see installation
manual).
One of the error codes appears Consult your local dealer.
Refer to the installation manual for a
detailed list of error codes.
The schedule timer does work but
the programmed actions are
executed at the wrong time
(e.g. 1 hour too late or too early)
Check if the clock and the day of the
week are set correctly, correct if
necessary.
The domestic hot water schedule
timer is programmed but does not
work.
In case the icon is not displayed,
push the button to enable the
schedule timer.
Capacity shortage Consult your local dealer.

- I reheat the reheat function can be activated next to or separate from the automatic storage operation if the user wants to keep the domestic hot water tank at the minimum reheat temperature 13
- I remark that only the time when domestic water heating must start and stop can be programmed in the schedule timer when domestic water heating is enabled the water will be heated till storage set point the storage set point is set through field setting 13
- Next to the standard domestic water heating operation modes it is also possible to freely program the domestic water heating operation through the schedule timer refer to programming domestic water heating on page 16 then the mode is switched on or off at a scheduled time 4 actions can be programmed per mode these actions are repeated daily additional schedule of storage on top of the automatic day and night storage functionality 13
