The CHV-TSTAT is a versatile heating and cooling thermostat for one- and two-stage control of forced air, radiant, and heat pump HVAC systems. Relative humidity capability can be added through an external remote humidity sensor (sold separately). Although functional as a standalone thermostat, the CHV-TSTAT delivers greatly enhanced functionality as part of a complete home automation system from Crestron®. Available in white, black, or almond, the stylish wall mount design is a complement to any décor.
