While the electrical supply and the fuel supply remain active, the boiler is
protected by the systems:
- heating anti-freeze: this function is activated if the temperature
measured by the flow sensor drops below 5°C. A heat request is
generated in this phase with the ignition of the burner at minimum output,
which is maintained until the outlet water temperature reaches 35° C;
- domestic hot water anti-freeze: the function starts if the temperature
measured by the DHW NTC probe falls below 5°C. A heat request is
generated in this phase with the ignition of the burner at minimum output,
which is maintained until the outlet water temperature reaches 55° C.
b
The activation of the ANTI FREEZE function is indicated by a scrolling
message on the foot of the REC10 display.
- circulator anti-locking: the circulator activates every 24 hours of
stoppage for 30 seconds.
5.18 Switching off for lengthy periods
If the EXCLUSIVE boiler is not used for a long time, the following operations
must be carried out:
- set the status of the boiler to OFF
- set the system's main switch to "off"
- close the fuel and water taps of the heating and domestic hot water
system.
In this case, the anti-freeze and anti-blocking systems are deactivated.
Drain the heating and domestic water system if there is any risk of freezing.
