• OUTDOOR THERMOSTAT (10-45F)

The Bard 8408-001 outdoor thermostat (10 to 45F) is an OEM temperature sensing control used in Bard wall mounted HVAC equipment to manage outdoor temperature based operation, helping the unit shift heating strategy and low ambient functions when conditions drop. When this thermostat is out of calibration or fails open or closed, you can see incorrect staging, nuisance lockouts, or poor comfort in colder weather, so replacing it with the correct Bard part number restores the intended control sequence and reliable system performance. Verify your unit model and the required cut in and cut out range before ordering, since Bard uses multiple outdoor and freeze protection thermostats across different series.
