Troubleshooting
Before replacing the fuse, try to determine why the fuse blew.
•
Check the Power wiring polarity of the Carrier® ChillerVu™, any attached expanders, and any other controllers
that share the power supply. Use the same polarity for all of them.
•
Verify that outputs are wired to the appropriate types of devices. See Outputs (page 18). For example, you
cannot wire a 24 Vac device to an output.
