Description
The TH 192 Aspirator Wall Box Kit is commonly installed on existing or newly constructed walls when it is desirable to conceal the controlling instrument either for aesthetic reasons or to prevent tampering, while at the same time maintaining high standards of control.

The TH 192 HC thermostats are proportional single output, dual set point, 2-pipe (high air capacity) sensor controllers. Each thermostat includes a wall mounting plate for installation in a variety of rough-in terminal boxes. Sensitive bimetals respond to temperature change to modulate control air through a flapper nozzle. Two set point dials are provided. When the supply air pressure changes from 18 to 25 psi (124 to 172 kPa), the thermostat automatically switches from the cooling to the heating set point respectively. 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
