711/06/2012 - 300028413-001-A

WARNING
Never cut the power to the solar control system, even
during extended absences. The control system protects
the installation against overheating in summer when it is
running.
WARNING
Do not modify the control system parameters unless fully
conversant with them.
During extended absences, we recommend lowering the set point
temperature in the solar DHW calorifier to 45°C. When the user is
present, the set point must be set to 60°C.

4.3 Setting the DHW calorifier outlet temperature
4.3.1. Programming and setting the electrical
back-up
The temperature of the volume of water heated by the electrical
resistor is set by the installer on commissioning of the installation
according to the size of the home.
Using the solar control system, it is possible to adjust the volume of
water heated to 40 °C by the resistor in two ways:
4Force the continuous heating of the resistor for significant
unforeseen needs.
¼ See chapter: "Force back-up", page 14.
4Select winter mode w (2 hours maximum according to the volume
of the domestic hot water required at 40 °C) to compensate for the
lack of sun in winter. If necessary, the period scheduled outside of
the off-peak hours is set between 16:00 and 18:00, i.e at the end
of the day when the solar contribution is reduced and just before
the drawing off period.

CAUTION
If the temperature in the solar collectors is higher than
130°C, the control system operates in safety mode. Wait
until the evening before start-up or cool down (cover) the
solar collectors.
Commissioning is performed by the installer. Once connected to the
power supply, the control system is in automatic mode. To disconnect
the solar pump, a minimum temperature of 30 °C is required at the
collector and a temperature difference of 6 °C with respect to the
domestic hot water calorifier.
If the particular conditions make it necessary to adjust the
settings, contact the installer.

5.1 General instructions
CAUTION
4Maintenance operations must be done by a qualified
engineer.
4Only original spare parts must be used.
5.2 Safety valve or safety unit
The safety valve or unit on the domestic cold water inlet must be
operated at least once a month to ensure proper operating and to
prevent from any overpressure which may that may damage the
domestic hot water calorifier.
WARNING
Failure to abide by this maintenance rule may damage the
domestic hot water calorifier and void its warranty.
5.3 Cleaning the casing material
Clean the outside of appliances using a damp cloth and a mild
detergent.
5.4 Checking the magnesium anode
The magnesium anode must be checked at least every 2 years. After
the first check, determine the frequency of future checks on the basis
of anode wear.
