– Dispose of the fan components according to the valid rules and laws.
7 .5 Error description
Error Unit behaviour Problem Solution
4 - Supply air fan error
Unit does not function. Fan overheating or damage to the ther-
mal contacts of the supply air fan.
Determine cause of motor overheating (e.g. faulty bearing, mechanical prob-
lem, short circuit, ...). The motor must be replaced, if necessary.
6 - Supply air filter blo-
cked
Unit ventilates. Filter blocked. Check condition of filter and replace filter, if necessary.
8 - Failure of pre-hea-
ter 1 Unit ventilates. Pre-heater overheating. 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.
9 - Heater battery 1 error
Unit ventilates. Heater battery overheating or damage
to temperature sensor. Check whether the air can flow through the unit freely.
12 - CO2 sensor error
Unit ventilates. Malfunction of air quality sensor. Check whether the CO2 sensor is connected correctly. Check function of
the CO2 sensor, if necessary (output signal value).
16 - Supply air -
Damage to external
temperature sensor
(T-EXT1)
Unit does not fun-
ction.
Temperature sensor error. 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 k
Ω
).
17 - Supply air -
Defective temperature
sensor after heater bat-
tery (T-EXT2)
Unit does not function. Temperature sensor error.
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 k
Ω
).
18 - Supply air -
Defective temperature in
supply air duct (T-EXT3)
Unit does not fun-
ction.
Temperature sensor error.
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 k
Ω
).
24 - Error concerning
water return temperature
sensor
(T_WATER_OUT)
Unit does not function. Temperature sensor error.
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 k
Ω
).
25 - Error concerning
room temperature sensor
(T_Room)
Unit ventilates. Temperature sensor error. 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 k
Ω
).
27 - Error concerning
supply air filter pressure
sensor
Unit ventilates. Pressure sensor error. Check whether the measuring device is damaged or contaminated. Check
whether the pressure hoses are not blocked. Replace the pressure sensor,
if necessary.
28 - Error concerning
supply air fan pressure
sensor
Unit does not function. Pressure sensor error.
Check whether the measuring device is damaged or contaminated. Check
whether the pressure hoses are not blocked. Replace the pressure sensor,
if necessary.
32 - Error concerning air
quality sensor
Unit ventilates. Malfunction of air quality sensor. Check whether the air quality sensor is connected correctly. Check function
of the sensor, if necessary (output signal value).
34 - Error concerning ex-
ternal temperature sensor
from BMS
Unit ventilates. Sensor error at BMS or incorrect data Check address and sensor value in BMS system. Check function of BMS
sensor.
50 - Supply air filter blo-
cked > 80 %
Unit ventilates. Filter blocked. Replace filter.
70 - Water heater battery
frost protection
Unit ventilates. Water heater battery frost protection
is active. 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.
71 - Water heater - Wait
for the water temperature
Unit ventilates. Water temperature assessment active. Process ends automatically.
72 - Water heater - Wait
for the supply air tempe-
rature
Unit ventilates. Supply air temperature assessment. Process ends automatically.
74 - Flow rate reduction,
minimum temperature in
duct not reached
Unit functions in limi-
ted mode. The unit attempts to reach the mini-
mum temperature. Supply air temperature is not reached. There is an automatic power correc-
tion (supply air fan is adjusted down).
