5.2.1 Controller
The power LED of the controller always remains lit up. If it
blinks, this means a problem has occurred. Please consult
your Installation Report, which can be found in the
Installation Manual.
Open the controller cover and identify the LED(s) that are
flickering in order to assess from which thermostat the alarm
is originating.

Battery Alarm:
Replace the batteries of the Thermostat when the
symbol appears.
5.2.3 Thermostat T-55 and Thermostat Public T-53
Battery Alarm:
Replace the batteries of the thermostat when the red LED
inside the thermostat blinks twice. (During a heat or cool
demand)
Cover Alarm:
The Thermostat Public T-53 includes a switch to warn in case
of opening the cover. The status of the switch is transmitted
by radio waves. Power LED and concerned channel LED blink.
5.3 Erasing the alarms
Each LED switches off as the corresponding problem is
solved, and the Power LED goes back to its normal state (i.e.
always on).
A blinking mains indicator indicates an alarm/an
error message.
