AIR HP
ERR
Air temperature
sensor defect
HP air temp. sensor data is illogical
Target temperature =
(max.water temp.+ min. water temp) / 2
Automatic
after repair
AMBIeNCE 1
ERR
Amb1 sensor
defect
Attention : the room temperature sensor
with display should be entered as INT
SENSOR for circuit 1 only
• Room temperature control for circuit 1
is programmed in just as SENSOR
and the data received is illogical
or
• It is not, so the swimming pool sensor
is recognised and the data received
is illogical
Heating request
Automatic
after repair
AMBIENCE 2
ERR
Amb 2 sensor
defect
Attention : the room temperature sensor
with display should be entered as INT
SENSOR for circuit 1 only
Circuit 2 is programmed as a radiator or
underfloor heating circuit with room
temperature sensor and the data received is
illogical
Heating request
Automatic
after repair
