ALARMS
This control governs two types of alarms:
 S erious Alarms: cause the forced switching off of the ther-
mostat
 N on-serious Alarms: do not cause the forced switching off
of the thermostat, but disable possible critical functions
SERIOUS ALARMS
Alarm code
 C ode A01= error of external air temperature sensor (in
case of on-board thermostat)
 C ode A02 = error of internal air temperature sensor (in case
of wall mounted thermostat and disconnected external air
temperature sensor)
NON-SERIOUS ALARMS
THERMOSTAT OFF
THERMOSTAT ON
 Code A03 = water sensor error
 Code A04 = external humidity probe error (only if a remote
temperature probe is installed)
 Code A05 = internal humidity probe error
N.B.: the alarm code is displayed only when the
thermostat is switched off
