The safety temperature limiter has triggered. Examine the air supply and filter. Consult the Operation Manual for the air treatment unit for more details.
What to do if CO2 sensor is missing in DencoHappel MATRIX OP71 Control Panel?
If the CO₂ sensor is missing, it means that the CO₂ sensor is defective. Check the connection of the sensor for a possible cable break or if it's simply missing, especially if the control software requires a CO₂ sensor.
What to do if humidity sensor is missing in DencoHappel MATRIX OP71?
If the humidity sensor is missing, it indicates that the humidity sensor is defective. Examine the connection of the sensor for a possible cable break or if it's not available, especially if the control software requires a humidity sensor.
What to do if pressure sensor is missing in DencoHappel Control Panel?
If the pressure sensor is missing, it means that the pressure sensor is defective. Examine the connection of the sensor for a possible cable break or if it's not available, especially if the control software requires a pressure sensor.
What to do if Frost protection thermostat is missing in DencoHappel Control Panel?
If the frost protection thermostat is missing, it means that the frost protection thermostat/sensor is defective. Check the connection of the sensor for a possible cable break or if it's missing, particularly if the control software requires a frost protection thermostat/sensor.
What to do if ext. RT sensor is missing in DencoHappel MATRIX OP71?
If the external RT sensor is missing, it means that the sensor of the room/return-air temperature is defective. Check the connection of the sensor for a possible cable break or if it's missing, even if the control software requires a sensor.
What to do if Inlet sensor is missing in DencoHappel MATRIX OP71 Control Panel?
If the inlet sensor is missing, it means that the inlet temperature sensor is defective. Check the connection to the sensor for a possible cable break or if it's missing, even if the control software requires a sensor.
What to do if OT sensor is missing in DencoHappel MATRIX OP71 Control Panel?
If the OT sensor is missing, it indicates that the sensor of the outside-air temperature is defective. Check the connection of the sensor for a possible cable break or if it is missing, even if control (software) requires a sensor.
What to do if ST sensor is missing in DencoHappel Control Panel?
If the ST sensor is missing, it indicates that the supply-air temperature sensor is defective. Check the connection to the sensor for a possible cable break or if it's missing, even if the control software requires a sensor.
What to do if Internal sensor is defective in DencoHappel MATRIX OP71?
