What to do if the Stulz Fan controller and the rest of the unit don't work?
If the controller and the rest of the unit aren't working, the possible causes are: * Main power supply missing: Restore power supply. * Main switch open: Close the main switch. * Power supply to the controller is missing: Check the voltage on the power supply cables and repair the broken cable or restore the missing connection. * Controller faulty: Contact STULZ service.
Why is the Stulz Fan controller working but the display is not working?
If the controller is working but the display isn't, it could be due to: a disconnected cable between the controller and display (reconnect it); a broken cable between the controller and display (replace the cable); a faulty display (contact STULZ service); or faults blocking the unit (look for alarms on the display and contact STULZ service).
What to do if there is a LAN failure in Stulz Fan?
If there is a LAN failure, possible causes include a missing LAN cable (connect units in LAN with a suitable cable), a LAN cable that is not pin-to-pin (replace it with a pin-to-pin cable), or a damaged controller (contact STULZ service).
