Siemens 192 DN/DNV Powerstar Day/Night/Vent Pneumatic Room Thermostats
Providing proportional dual setpoint, 2-pipe or 3-pipe high air capacity pneumatic room temperature control, the 192 DN or DNV Powerstar Pneumatic Room Thermostat automatically resets the room temperature setpoint during unoccupied hours by changing the air pressure to the thermostat. A manual override feature allows occupants to switch to day mode. The override returns to night mode the following night.
• Dual setpoint dial available in Fahrenheit or Celsius scales
• Available in direct or reverse acting models
• Sensitive bimetal responds to temperature changes
• Manual override selector for off-hour occupant comfort
• Adjustable changeover pressure
• Large volume air capacity relay
• Integral, field adjustable limit stops
• 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 dial, restrictor and filters
