Designed for temperature control of heating and cooling
applications, the 192 HC Powerstar Heating/Cooling Pneu-
matic Room Thermostat controls valves and damper actua-
tors in cooling equipment. Providing energy management
and occupant comfort, the thermostat automatically adjusts
to seasonal changes from heating set point to cooling set
point in commercial and institutional facilities.
Recommendation
For control of multiple valves and actuators, use with or
without high/low limiting controls.
Providing proportional single output, dual set point with
2-pipe for high air capacity pneumatic room temperature
control, the 192 HC Powerstar Heating/Cooling Pneu-
matic Room Thermostat provides two thermostats under
one cover; one side for heating and the other for cooling.
Switchover is accomplished by changing the air pressure to
the thermostat.
