10. Troubleshooting for Technician
Problem: The display is blank.
Solution: The unit is not getting 220 Vac.
Check the wiring connections, Rh (Phase for heat), Rc(Phase for cool), C(common).
If you are using one phase for cool and heat, check that Rc, Rh are shorted and common is tight.
Problem: In heat mode, unit sends cool air.
Solution: The Auto Fan is not ON.
Problem: Ambient temperature with external sensor is not accurate.
Solution: Adjust Offset to 0ºC (see 8.5).
