Siemens 193 HC Powerstar (Hesitation) Free Energy Band Heating/Cooling Pneumatic Room Thermostats

Powerstar (Hesitation) Free Energy Band Heating/Cooling Pneumatic Room Thermostats
193 HC

Providing proportional, single output, dual setpoint, 2-pipe pneumatic room temperature control, the 193 HC Powerstar (Hesitation) Free Energy Band Heating/Cooling Pneumatic Room Thermostat is designed to sequence a heating device or a cooling device. The hesitation feature keeps the output pressure constant through a 6°F (10.8°C) range (typical), causing a deadband.

• Dual setpoint dials available in Fahrenheit or Celsius scales
• Sensitive bimetal responds to temperature changes
• Integral, field adjustable limit stops
• Adjustable Free Energy Band
• Wall mounting plate for connection to a variety of rough-in terminal boxes included
• Test port for fast check of output pressure without removing the cover
• Field replaceable thermometer, setpoint dials, restrictors, and filters Options
