Troubleshooting/Repair Helps

1. This EZGEO controller contains several interference suppression components, but as an electronic logic

product, unpredictable and unusual transients or interferences may sometimes cause strange results. If the

EZGEO controller is “acting strange”, one immediate step would be power down reset. Simply turn off the 24-

volt source power (probably furnace or air handler circuit breaker), when the green LED goes out, count to 10,

and re-energize power supply.

2. The terminal blocks for control wire hook-up are designed for a wire insertion and screw clamp down. If there is

no wire connected and the screw is loose, the screw may not necessarily make a good electrical contact to the

inside components. Example – if you are jumpering the thermostat terminals without thermostat wire connection

or if you are attempting to measure voltage on the screw head, you may get erroneous or unpredictable results if

the screw is not tightened down.

3. Use general heating system logic information and basic understanding of the terminal block wiring functions

when measuring voltage to determine proper operation of this module.

4. The outdoor sensor must be located outdoors for this controller to correctly operate. Do not leave the outdoor

sensor “hanging in conditioned space” and attempt to run this system. Note: OT sensor tip must be up.
