FUNCTIONS
FREEZE-PROTECTION
The freeze-protection control is only active in stand-by function. If the boiler temperature is
≤
8°C, and the
outside temperature (if the external probe is present. If not, reference is only made to the boiler temperature) is
≤
-5°C, the boiler is activated until the temperature value set at parameter P03 is reached.
If the water heater temperature is
≤
P03 +2°C, also the water heater circulator is activated.
Once the boiler temperature P03 value has been reached, the heating circulator is activated for a time referred
to parameter P14, and the water heater circulator is stopped.
Once the function has been performed, the system sets to stand-by.
SEIZURE-PROTECTION
In any operating condition (except for stand-by), each circulator is activated for 15 seconds every time the
current hour passes 12.00 of each Monday.
TIME COUNTERS
They register the number of operating hours for each of the 4 connectable circulators.
LEGIONELLA-PROTECTION
The system activates the antibacterial function at least every 168 hours, and the water heater temperature is
“forced” to a value equal to the parameter set, P04 -5°C.
