What happens if there is a sensor fault BT6 (hot water, controlling) in my Nibe Water Heater?
If the BT6 sensor (hot water, controlling) in your Nibe Water Heater has a fault, it will use BT54 instead.
What happens if there is a sensor fault EQ1–BT64 in my Nibe Water Heater?
If the EQ1–BT64 sensor in your Nibe Water Heater is not connected or defective, cooling will shut off, and the shunt (QN18) for cooling will close.
What does sensor fault BT63 mean on my Nibe Water Heater?
If the BT63 sensor in your Nibe Water Heater has a fault or is not connected, the internal electrical addition will be blocked.
What does sensor fault EP30 - BT54 mean on my Nibe Water Heater?
If there's a sensor fault with EP30 - BT54 (solar coil) in your Nibe Water Heater, the solar function will switch off.
What happens if my Nibe Water Heater displays sensor fault EP21 - BT2?
If there is a sensor fault EP21 - BT2 (supply temperature sensor, extra climate system 1) in your Nibe Water Heater, it will control the return sensor (EP21-BT3).
What does sensor fault EP23- BT2 mean on my Nibe Water Heater?
If there is a sensor fault EP23- BT2 (supply temperature sensor, extra climate system 3) in your Nibe Water Heater, it will control the return sensor (EP23-BT3).
What does sensor fault BT1 mean on my Nibe Water Heater?
If the BT1 sensor (outdoor sensor) in your Nibe Water Heater has a fault or isn't connected, the calculated flow temperature is set to the minimum supply line (menu 1.9.3).
What happens if there is a sensor fault BT2 in my Nibe Water Heater?
If the BT2 sensor (heating medium supply) in your Nibe Water Heater has a fault or isn't connected, it will use BT3 if available. If BT3 is not available, BT63 is used.
