Siemens 193-216 Powerstar Pneumatic Room Thermostat 2-Pipe Heat/Cool Dual Setpoint

The Siemens 193-216 is a Powerstar Free Energy Band pneumatic room thermostat designed for energy-efficient heating and cooling control in commercial buildings. This dual setpoint, dual output thermostat is ideal for buildings with early morning heat requirements and mid-morning to afternoon cooling demands, automatically sequencing heating and cooling valves to minimize energy waste.

Key Features:

• Direct acting (DA) for heating and reverse acting (RA) for cooling applications
• 4-degree Fahrenheit deadband between heating and cooling changeover creates a "Free Energy Band" where no heating or cooling occurs
• Dual setpoint dials with Fahrenheit scale (45°F to 85°F range)
• Two-pipe configuration for proportional control
• High air capacity output for demanding applications
• Sensitive bimetal element responds to temperature changes through flapper nozzle control
• 18 to 25 PSI air supply requirement
• Includes wall plate and mounting screws for easy installation

This pneumatic thermostat produces proportional output signals that modulate pneumatic valves and damper actuators in response to load changes, providing precise temperature control while maximizing energy savings. Air connections are made with 5/32 inch O.D. plastic tubing. Cover sold separately.
