The generally applicable safety at work and accident prevention regulations must be observed!
– Electrical work must only be carried out by an authorised electrician.
– Use appropriate lifting equipment and fastening devices to dismantle the fan, Observe transport sketch!
– Dispose of the fan components according to the valid rules and laws.

Problem
Determine cause of motor overheating (e.g. faulty bearing, mechanical prob-
lem, short circuit, ...). The motor must be replaced, if necessary.
Check condition of filter and replace filter, if necessary.
Check whether the air can flow freely through the unit and the electric
pre-heater has sufficiently cooled down. Check the activation of the safety
temperature limiter.
Check whether the air can flow through the unit freely.
Check whether the CO2 sensor is connected correctly. Check function of
the CO2 sensor, if necessary (output signal value).
Check whether the sensor is correctly connected to the electronics. Carry
out a function test with the sensor by means of resistance measurement, if
necessary (the resistance value at +20 °C is around 10 kΩ).
Check whether the sensor is correctly connected to the electronics. Carry
out a function test with the sensor by means of resistance measurement, if
necessary (the resistance value at +20 °C is around 10 kΩ).
Check whether the sensor is correctly connected to the electronics. Carry
out a function test with the sensor by means of resistance measurement,
if necessary (the resistance value at +20 °C is around 10 kΩ).
Check whether the sensor is correctly connected to the electronics. Carry
out a function test with the sensor by means of resistance measurement, if
necessary (the resistance value at +20 °C is around 10 kΩ).
Check whether the sensor is correctly connected to the electronics. Carry
out a function test with the sensor by means of resistance measurement, if
necessary (the resistance value at +20 °C is around 10 kΩ).
Check whether the measuring device is damaged or contaminated. Check
whether the pressure hoses are not blocked. Replace the pressure sensor,
if necessary.
Check whether the measuring device is damaged or contaminated. Check
whether the pressure hoses are not blocked. Replace the pressure sensor,
if necessary.
Check whether the air quality sensor is connected correctly. Check function
of the sensor, if necessary (output signal value).
Check address and sensor value in BMS system. Check function of BMS
sensor.
Replace filter.
Automatic protection of water heater battery is active to prevent damage at
low temperatures. This function ends automatically as soon as the return
temperature has reached the target value.
Process ends automatically.
Process ends automatically.
Supply air temperature is not reached. There is an automatic power correc-
tion (supply air fan is adjusted down).
