Antifreeze function

The system has a frost protection.
Frost protection of the external unit : the primary circulator of the
internal unit is switched on if the return water temperature to the
external unit is equal to or less than 7 ° C for more than two conse-
cutive minutes. If the water temperature reaches and exceeds 8 ° C
for more than two consecutive minutes, the pump is turned off . In
the case of return temperature probe failure, the function refers to
the values of the fl ow temperature probe.
In the case in which the antifreeze function of the external unit is not
suffi cient, the frost protection of the internal unit will be automatically
activated. Also in this case the primary circulator of the internal unit
is switched on if the return water temperature to the external unit is
less than or equal to 7 ° C for more than two consecutive minutes. If
the water temperature reaches and exceeds 9 ° C for more than two
consecutive minutes, the pump is turned off . In the case of return
temperature probe failure, the function refers to the values of the
fl ow temperature probe.
In case of the circulation of water provided by the main pump is still
not suffi cient to ensure a frost protection, the system will automati-
cally manage the ignition of the entire external unit and of the elec-
trical resistances .
