Schneider Electric (Barber Colman) THCR-4 Enthalpy Controller Refrigerant This industrial pneumatic room thermostatThe Schneider Electric (Barber Colman) THCR 4 Enthalpy Controller is a high precision analog electronic sensor designed for economizer cooling control in commercial HVAC systems. This SPDT changeover control measures both dry bulb temperature and relative humidity to determine the total heat content of outdoor air, ensuring the system only utilizes free cooling when the outside air is more efficient than mechanical refrigeration. Operating on a 24V AC
