Solution
Buffer tank temperature sensor open:
Bad connection: check the wiring and connec­
tors
Incorrectly fitted sensor: check that the sensor
has been correctly fitted
Sensor is not present.
Faulty sensor: replace the sensor
Buffer tank temperature sensor short-circuited:
Bad connection: check the wiring and connec­
tors
Incorrectly fitted sensor: check that the sensor
has been correctly fitted
Faulty sensor: replace the sensor
Buffer tank top temperature sensor open:
Bad connection: check the wiring and connec­
tors
Incorrectly fitted sensor: check that the sensor
has been correctly fitted
Sensor is not present.
Faulty sensor: replace the sensor
Buffer tank top temperature sensor short-circuit­
ed:
Bad connection: check the wiring and connec­
tors
Incorrectly fitted sensor: check that the sensor
has been correctly fitted
Faulty sensor: replace the sensor
Buffer tank temperature sensor not detected:
Buffer tank temperature sensor is not connec­
ted: Connect the sensor
Buffer tank temperature sensor is not connec­
ted correctly: Connect the sensor correctly
Faulty sensor: replace the sensor
Buffer tank top temperature sensor not detected:
Buffer tank top temperature sensor is not con­
nected: Connect the sensor
Buffer tank top temperature sensor is not con­
nected correctly: Connect the sensor correctly
DHW circulation temperature open:
Sensor is not present.
Bad connection: check the wiring and connec­
tors.
Incorrectly fitted sensor: check that the sensor
has been correctly fitted.
Faulty sensor: replace the sensor.
DHW circulation temperature sensor short-circuit­
ed:
Bad connection: check the wiring and connec­
tors.
Incorrectly fitted sensor: check that the sensor
has been correctly fitted.
Faulty sensor: replace the sensor.
DHW Mixing temperature sensor open:
Sensor is not present.
Bad connection: check the wiring and connec­
tors.
Incorrectly fitted sensor: check that the sensor
has been correctly fitted.
Faulty sensor: replace the sensor.
