- Rotate the CH to minumum position. The summer mode will be active and the system will go back
to stand-by mode again.
Frost Protection
The appliance goes on and off automatically depending on actual water temperature values measured
by the sensors for protecting water circuits against freezing. This function protects both CH and DHW
systems. Frost protection has 2 level:
a) Frost protection level 1
- When the appliance in stand-by mode and the CH sensor measures a low water temperature in the
system (less than 8 °C ), the pump runs. When the CH water temperature goes above 10 °C (measured
on the CH sensor), the pump will stop.
b) Frost protection level 2
- When the appliance in stand-by mode and the CH sensor measures a low water temperature in the
system (less than 6 °C ), the boiler starts as if there was a CH demand. When the CH water
temperature goes above 15 °C (measured on the CH sensor), the CH demand will end (burner will be
off). During frost protection the burner will run with minimum capacity.
- The same situation occurs when DHW sensor measures less than 6 °C. The boiler starts and when
the water temperature goes above 15 °C, the boiler will turn stand-by mode.
: The appliance must be on stand-by mode to activate frost protection
system.
Pump Anti-Seize Function
Anti-seize protection’s function prevents the pump from probable blocking when the pump stays
inactive for a long period of time. This function goes on automatically if the pump has been inactive
for at least 24 hours and runs the pump for 5 sn. in CH mode. In monothermic types, pump anti-seize
function and 3-way valve protection becomes active together and the 3-way valve changes
position against blocking.
