The TH 192 S thermostats are proportional single output, single set point, 1-pipe (low
air capacity) or 2-pipe (high air capacity) sensor controllers. Each thermostat includes a
wall mounting plate for installation in a variety of rough-in terminal boxes. A sensitive
bimetal responds to temperature change to modulate control air through a flapper
nozzle. One set point dial is provided. 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.
