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

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

Providing proportional, dual output, dual setpoint, 2-pipe (dual 1-pipe low air capacity) or 3-pipe (dual 2-pipe high air capacity) pneumatic room temperature control, the 193 HC Powerstar Free Energy Band Pneumatic Room Thermostat creates a deadband so that no heating or cooling occurs during the Free Energy Band.

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