Honeywell/Barber Colman Enthalpy Controllers

Measuring enthalpy in intake air helps to keep your cooling costs lower by deciding when the outside air contains too much moisture. Enthalpy is a measure of the total heat content in the air. These controls are available in two-position and electronic versions.

Remember: It takes 1 BTU to remove 1 degree of heat. It takes 1000 BTU’s to condense 1 pound (pint) of moisture.
