8403-064 OBSOLETE
- Digital Thermostat/Controller
The Bard 8403-064 Digital Thermostat/Controller is an OEM low-voltage wall controller used on select Bard wall-mounted HVAC units to manage heating and cooling calls through the unit control wiring. It is specified in Bard equipment literature as the required controller for certain models, so replacing a failed or damaged thermostat with the correct 8403-064 helps restore proper staging, fan operation, and overall unit sequencing without guesswork. Because controller compatibility can vary by unit series and wiring harness, confirm the exact model and wiring diagram for your Bard unit before ordering to ensure the terminals and control strategy match your application.
