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.
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.
CAUTION
The anitfreeze protection does not function if the
4
boiler is switched off.
The integrated protection system only protects the
4
boiler, not the installation. To protect the installation,
set the appliance to HOLIDAYS mode.
With the IniControl control panel, the HOLIDAYS mode is
only available if a room sensor is connected to the boiler.
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).
To configure the holidays mode: ¼ See chapter: "Selecting the
operating mode", page 20.
