ALARMS
This control governs two types of alarms:
■ Serious Alarms cause the forced switching off of the ther-
mostat
■ Non-serious Alarms do not cause the forced switching off
of the thermostat, but disable possible critical functions
SERIOUS ALARMS
Alarm code
■ Code A01 = error of external air temperature sensor (in case
of on-board thermostat)
■ Code 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 sensor is installed)
■ Code A05 = internal humidity probe error
N.B.: the alarm code is displayed only when the ther-
mostat is switched off
