The battery compartment on the Honeywell T3 is located behind the front case. To access it, lift up the front case, then slide down the section with two small bumps to remove the batteries.

The alert triangle only is flashing on our new T3R wireless programmable thermostat. Why?

The alert triangle is flashing on the Honeywell T3R wireless programmable thermostat because the thermostat has likely lost its wireless connection (binding) with the receiver unit. This can be identified by a red flashing light on the receiver unit and either no wireless symbol on the thermostat display or a flashing wireless symbol with the warning triangle. Re-binding the thermostat and receiver unit is required to restore the connection.

If there is no display on your Honeywell T3 thermostat after changing the batteries, ensure that you have used 2 new 1.5V LR6 AA alkaline batteries as required. Check that the batteries are correctly inserted with the correct polarity. If the problem persists, the thermostat might need a reset or could have a hardware issue.
