The Freeze Protection menu allows the feature to be enabled
and disabled. The built-in frost protection mechanism activates
the system pumps as soon as the ow temperature [NTC1
probe] drops below 46°F. As soon as the ow temperature is at
42°F, the burner starts up until the ow temperature rises above
60°F. The pumps continue to run for around 10 minutes.
Select Enabled or Disabled using the UP or DOWN keys,
then store the setting with the OK key.
• Enabled – The Freeze Protection feature protects the in-
stallation from freezing at a predetermined system ow
temperature.
• Disabled – The Freeze Protection feature is disabled.
Only the pumps operate.
Default: Enabled
Frost Protection Setpoint allows to dene the outside air
temperature at which the anti-freeze function is activated
(only available if an outdoor temperature sensor is connected).
The pumps are activated when the outside temperature drops
below the threshold dened in this menu.
Adjust the Frost Protection Setpoint using the LEFT or
RIGHT keys, then store the setting with the OK key.
In order to enable the protection of the whole
system against freezing, all the valves of the
radiators and the convectors should be com-
pletely open.
Default: -22°F
CAUTION
The appliance should NEVER be installed in
a location where freezing could occur. Sub-
jecting the appliance to freezing conditions
could lead to freezing of the condensate pos-
sibly causing serious injury or death.
Freeze Protection should only be disabled
when the system contains antifreeze to pre-
vent the system from freezing. Serious damage
could occur to the appliance as well as the en-
tire heating system if Freeze Protection is dis-
abled without antifreeze in the system.
