3a SWITCHING OFF
Temporary switch-off
In case of absence for short periods of time, set the mode selector (fig.
32) to (OFF).
In this way (leaving the electricity and fuel supplies enabled), the boiler is
protected by:
Anti-frost device: when the temperature of the water in the boiler falls below
5°C, the circulator and, if necessary, the burner are activated at minimum
output levels to bring the water temperature back to the values for safety
(35°C). During the anti-frost cycle, the symbol
digital monitor.
Circulator anti-blocking function: an operation cycle is activated every
24 hours.
Switching off for long periods
In case of absence for long periods of time, set the mode selector (fig. 32) to
(OFF). Turn the main system switch OFF. Close the fuel and water taps
of the heating and domestic hot water system. In this case, anti-frost device
is deactivated: drain the systems, in case of risk of frost.
