HEATING PUMP ANTI-LOCKING FUNCTION
An anti-locking function activates the circulator for 30 seconds every 24 hours of inactivity. Following a power failure, the
first anti-locking intervention occurs after 1 hour of inactivity. The function is active even when operation is locked and
the selector is set to OFF.
SWITCHING VALVE ANTI-LOCKING FUNCTION
An anti-locking function activates the switching valve for 30 seconds every 24 hours of inactivity. Following a power
failure, the first anti-locking intervention occurs after 1 hour of inactivity. The function is active even when operation is
locked and the selector is set to OFF.
ANTI-LEGIONELLA FUNCTION
In the boiler version with water heater the anti-Legionella function can be activated/deactivated by acting on the display.
The function is activated once every two weeks (336 hours), forcing the water heater setpoint to 70°C, and is deactivated
when the water temperature in the water heater remains > 70°C for 15 min. Should a sanitary water request reduce the
temperature to a value < 70°C, the time already elapsed is stored. When the temperature once again exceeds 70°C, the
function continues from the time previously elapsed until reaching 15 min.
A timer is in any case activated when the anti-Legionella function starts and deactivates the function after a maximum time
of 30 minutes. The timer does not stop if sanitary water is drawn.
ANTI-FREEZE FUNCTION
The boiler is equipped with an anti-freeze function. When the water temperature read by the delivery sensor drops to below
the “pump activation temperature for anti-freeze”, the pump is activated to put the water back into circulation.
Should the temperature drop even further to the “burner activation temperature for anti-freeze”, also the burner will start
waiting for the delivery temperature to exceed the “anti-freeze deactivation temperature” beyond which the burner is tur-
ned off and a post-circulation cycle is activated. The function remains active even if the heating selector is set to OFF,
SUMMER and WINTER.
