3. Check whether there is voltage at
the power feed to the control unit/
electronics; provide power if
required.
4. Check the plug-in and threaded
connections.
5. Replace the power supply unit.
6. Replace the programming unit.
7. Replace the main PCB.
Refrigerant circuit service valves
!
Please note
If work on the refrigerant circuit is carried out incorrectly, there is a risk of
equipment damage.
The following steps must only be carried out by authorised contractors.
