Alarm
AL04
Boiler overtem-
perature (Boiler
set + 5°C)
AL05
Unit timeout =
unit resistor off
AL06
Unit temperature
probe in short
circuit
Cause
The alarm is enabled if the
boiler temperature probe re-
ads a temperature of 5° higher
than the set one
The alarm is enabled if the
unit probe does not rise above
50°C in 3 min. after the first
Power On of the resistor (TR1)
The alarm is enabled
if the unit temperature probe
reads the maximum range and
is therefore in short circuit
Effect
The boiler heating and boiler loading
functions are inhibited; the unit with
all its functions continues working.
The alarm display is canceled by
pressing the encoder but the boi-
ler remains inhibited until the next
POWER ON
The unit heating function is disabled;
the boiler continues working.
The alarm display is canceled by pres-
sing the encoder but the unit remains
inhibited until the next POWER ON
The unit heating function is disabled;
