- NON PROGRAMMABLE DIGITAL THERMOSTAT TH5220D1151
Bard part number 8403-058 is a Honeywell TH5220D1151 non programmable digital thermostat used to control Bard wall mounted air conditioners and heat pumps with standard 24 volt low voltage wiring. This OEM thermostat can be configured for either heat pump operation (up to 2 heat 1 cool) or conventional heat cool systems (up to 2 heat 2 cool), and it supports auto or manual changeover for straightforward comfort control in light commercial and modular applications. It is commonly used as a service replacement for several older Bard and Honeywell thermostat models, so it is a practical choice when you need a reliable, direct fit control that restores proper staging and system operation, but always confirm terminal connections and setup options against your unit wiring diagram and the Bard manual before installation.
