Troubleshooting Information

1. The thermostat does not call for heat and/or cooling.
   • Check that connector pins are straight and intact
   • Check that the thermostat is fully seated on the mounting plate. If the terminals are not fully engaged, the firmware cannot activate the relays. This prevents power surges to the HVAC system.
2. The heating and cooling demands are reversed.
   • Check that the thermostat is configured properly: Heat Pump (HP) or Furnace/Air Conditioner (NON-HP). If the Heat pump checks that the O/B Configuration under SETTINGS is correct.
   • Check that the wiring is correct, especially the Y and W wires. If used with a Heat Pump, check that the O/B wire is correct.
3. The fan does not turn on.
   •  Check that the wiring is correct, especially the G wire.
   •  If heating with oil or gas, make sure the furnace is working. In gas heat mode (HG), the fan is
     controlled by the furnace to avoid supplying cold air when the unit is starting.
4. The display does not appear after the batteries have been replaced.
   •  Press the reset button on the bottom of the thermostat with a pin, straightened paper clip or similar object.
