- Hold down actual temperature key for each zone to view current output when the heat module is on.
- Exchange zone module with another one. Turn zone on and check for error. If error moves to another zone, replace the faulty module. (When there is a high current error, the LED on that zone's module will turn red while the error is displayed.
- Check continuity of transformer windings, and if shorted to ground.
