4.4 Installation shutdown
CAUTION
Do not switch off the boiler. If the central heating system
is not used for a long period, we recommend activating the
HOLIDAYS
mode.
4.5 Frost protection
When the heating water temperature in the boiler falls by too much,
the integrated protection system in the boiler starts up. This protection
functions as follows:
4
If the water temperature is lower than 7°C, the heating pump starts
up.
4
If the water temperature is lower than 4°C, the boiler starts up.
4
If the water temperature is higher than 10°C, the boiler shuts down
and the heating pump continues to run for a short time.
4
If the water temperature in the storage tank is less than 7°C, it is
reheated to its set point.
CAUTION
4
The anitfreeze protection does not function if the
boiler is switched off.
4
The integrated protection system only protects the
boiler, not the installation. To protect the installation,
set the appliance to HOLIDAYS mode.
The HOLIDAYS mode protects:
4
The installation if the outside temperature is lower than 3°C
(factory setting).
4
The room temperature if a remote control is connected and the
room temperature is lower than 6 °C (factory setting).
4
The domestic hot water tank if the tank temperature is lower
than 4 °C (the water is reheated to 10 °C).
