Remedy
- Check actual temperature
- Look at parameters A1 and A3
- Check actual temperature
- Look at parameters A5 and A7
- Check actual temperature
- Look at parameters A5, A6 and A5
- Check the reasons that have provoked the
activation of the input
- Look at parameters i0 and i1
- Check the reasons that have provoked the
activation of the input
- Look at parameters i1 and i5 (if parameter i5 =
value 3, there will be no effect; if parameter i5 =
value 4, the compressor will be turned off)
- Check the reasons that have provoked the
activation of the multipurpose input
- Switch device on/off
- Look at parameters i1, i5, i7, i8 and i9
- Press any button to restore normal operation
and switch off the buzzer
- Check the connection between the device and
the programming key
- Check whether the programming key is working
correctly
- Repeat the copying process
- Check the agreement of the firmware versions
(check manufacturing date)
- If necessary, replace device
- Press any button to restore normal operation
and switch off the buzzer
- Unplug/plug in the device
- Check the connection between the device and
the programming key
- Check whether the programming key is working
correctly
- Repeat the copying process
- Restore the default setting for the parameter
configuration
- Look at parameter P0
- Check whether the sensor (1/2/3) is working
correctly
- Check the connection between the device and
the sensor
- Check actual temperature
