Bard CMH-14A Outdoor Thermostat Control Kit

The Bard CMH-14A is a field-installable outdoor thermostat kit designed for use with Bard wall-mount HVAC systems. This control accessory provides critical temperature management by monitoring outdoor ambient conditions and automatically adjusting heating operation based on external temperatures.

Key Features:

• Field-installable outdoor thermostat control kit for Bard HVAC equipment
• Automatically switches from mechanical heating (compressor) to electric heat when outdoor temperatures drop
• Capillary tube and sensing bulb design for accurate outdoor temperature monitoring
• Mounts within the blower compartment with included mounting hardware
• Can also be configured to limit the quantity of available electric heat stages
• Adjustable temperature setpoint for customized operation
• Complete kit includes thermostat, capillary tubing, sensing bulb, mounting screws, cable ties, and vinyl-covered clamps

The CMH-14A outdoor thermostat is designed to take mechanical heating offline and send the compressor signal to energize electric heat in its place, making electric heat the first stage of heating during low ambient conditions. This helps optimize energy efficiency and prevents compressor operation in extremely cold outdoor temperatures. Installation requires routing the capillary tube and sensing bulb from the control panel through to the condenser section where it monitors actual outdoor ambient conditions.
