Each thermostat includes a wall mounting plate for installation in a variety of rough-in terminal boxes. Sensitive bimetals respond to temperature changes to modulate control air through a flapper nozzle. As the heating load decreases due to internal heat gains, a dead band of control minimizes energy consumption while the setpoint changes from 72°F (22°C) heating mode to 78°F (26°C) cooling mode. Two setpoint dials allow adjustment of the dead band 4°F (2°C) minimum. Air connections are made with 5/32-inch (4 mm) O.D. plastic tubing, directly to the thermostat chassis for retrofit applications or with plug-in adapters (provided with the TH 192 rough-in terminal box or optional accessories), which slide into the wall mounting plate. Features • Direct and reverse acting for heating and cooling modes. • Two separate, adjustable temperature setpoint indicating dials. • Two highly sensitive bimetal thermostatic elements. • Fahrenheit or Celsius models. • Individual field adjustable sensitivity with graduated scale. • Integral field adjustable limit stops. • Control pressure test port accessible without removing cover. • Easily replaceable thermometer, setpoint dials, filters and restrictor plate. • Covers available for concealed or exposed thermometers, and for concealed adjustment and setpoint indication. • Standard plastic thermostat covers provide Desert Beige or white finish. Application TH 193 HC thermostats control space temperature and take advantage of the dead band to “float” room temperature between heating and cooling modes while maintaining energy management (maximum economy) and occupancy comfort. TH 193 HC thermostats control valve and damper actuators in building applications that require early morning heat and afternoon cooling.
