Troubleshooting
If your ecobee3 does not power on, please check the
following:
1. Check that all wires are properly inserted into the
terminal blocks at the thermostat. Tug on the wires to
ensure they are not loose.
2. Some HVAC equipment has a safety switch that cuts
off power to the equipment if the equipment cover
panel is not closed properly. Please ensure the cover
panel of the equipment is closed properly.
3. If you installed the PEK, ensure R wire is connected
to Rc only and G wire is inserted properly into the
terminal.
4. If you have a multi-meter, please check the AC voltage
between Rc and C or Rh and C and ensure it is 24V.
5. If your device still does not power on, please call
