• Digital Tstat/Controller 5-Ton

Bard part 8403-065 is an OEM digital thermostat and controller used to manage temperature operation on select Bard wall-mounted air conditioners and heat pump applications, including common 5-ton light commercial and school installations. As a low-voltage wall controller, it provides the proper control signals to the unit so staging, fan calls, and mode operation occur as designed by Bard, which helps avoid nuisance issues that can come from mismatched aftermarket thermostats. If you are replacing a failed or damaged controller, confirm the exact unit model and wiring requirements in the Bard installation instructions or unit wiring diagram before ordering to ensure correct compatibility and configuration.
