The Siemens 192-203 Powers Controls Thermostat is a proportional single output, single set point, 2-pipe (high air capacity) sensor controller. Includes a wall mounting plate for installation in a variety of rough-in terminal boxes, a sensitive bimetal which responds to temperature change to modulate control air through a flapper nozzle, and one set point dial. Air connections are made with 5/32” (4 mm) OD 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 The Siemens 192-203 Powers Controls thermostat is a reverse-acting two-pipe relay which features Fahrenheit set point dials, a highly sensitive bimetal thermostatic element, field adjustable sensitivity with graduated scale, integral field adjustable limit stops, a control pressure test port that is accessible without removing cover, and easily replaceable thermometer, set point dial, filters, and restrictor plate. Covers are available for concealed or exposed thermometers and for either concealed, key, or exposed knob adjustment and set point indication. The standard plastic thermostat covers include desert beige or white finish. Optional design features include fixed temperature limit stops which meet government specifications, competitor adapter mounting kits, metal covers in a variety of finishes, and optional 1/2” large set point adjustment knobs.
