6 .2 .6 Frost protection
The heating unit electronic control includes a frost
protection function. When the flow temperature sinks
to below a minimum value, the burners start working at
minimum power according to the procedure used to set
the functional parameters.
The frost protection mode is activated even if the external
probe (supplied with the appliance) is not connected to the
boiler: parameters 14 (related to the Ch1 high temperature
system) and 22 (Ch2 low temperature system) are in fact in
default and set in weather function.
Should one not want to connect the probe, the boiler must
be made to work at a fixed point to avoid problems. The
parameter 14 and 22 settings may only be altered by a
Technical Assistance Centre authorized by B .
b
Power and fuel gas supply must be activated and
the water system at a correct pressure for the frost
protection system to function.
Glycol can be used as an additive for the system (up to a
maximum of 50%) there where considered necessary by
the person responsible for the project, keeping in mind that
this substantially reduces efficiency as it alters the specific
heat of the fluid.
Furthermore several parts of the system could be damaged
by altering the pH.
