Siemens 192 HC Powerstar Heating/Cooling Pneumatic Room Thermostats
Providing proportional single output, dual setpoint with 2-pipe for high air capacity pneumatic room temperature control, the 192 HC Powerstar Heating/Cooling Pneumatic 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.
• Dual setpoint dial available in Fahrenheit or Celsius scales
• Available in direct or reverse acting models
• Sensitive bimetal responds to temperature changes
• Integral, field adjustable limit stops
• Adjustable changeover pressure
• Large volume air capacity relay
• Wall mounting plates provides connection to a variety of rough-in terminal boxes
• Test port for fast check of output pressure without removing the cover
• Field replaceable thermometer, setpoint dials, restrictor and filters Options
