DIAGNOSTICS
and press
The diagnostic display shows the status of the sensors. Description of the
diagnostic display:
a
– floor sensor
b
– room sensor
c
– internal sensor
d
– sensor working properly
e
– sensor not working – open circuit
f
– sensor not working – short circuit
If a fault is indicated on sensor (b) or (c), replace the thermostat. If a fault is
indicated on sensor (a), replace the floor sensor. If the floor sensor (a) is
faulty, the thermostat can only work as a room thermostat, and only if the
user changes the thermostat function from floor or floor/room thermostat to
room thermostat. If a sensor is damaged or open circuit, the thermostat
contact opens, the LED starts to flash (twice a second) and a fault message
is displayed. If the floor sensor is faulty it must be replaced. If the room
sensor is faulty, the thermostat must be replaced.
