Dual Setpoint/Deadband Room Thermostat
Model Chart
Specifications
The dual setpoint/deadband pneumatic room
thermostats are designed for the proportional
control of pneumatic valves, damper actuators, and
other final control devices in environmental control
systems. These devices are for use when it is
desirable to set up a temperature span within
which the HVAC system uses no energy for heating
or cooling between selected heating and cooling
setpoints. The high capacity, two pipe,
pilot-operated relay type design provides
pneumatic feedback for accuracy and stability over
the entire operating range.
Features:
• Attractive appearance (various metal or ABS plastic covers
available).
• Factory calibrated. S.S. ball-in-seat provides pneumatic
feedback for linear, stable operation.
• Deadband is set merely by setting desired heating and
cooling setpoints.
• Deadband output pressure factory set at 8 psig; field
adjustable.
• Leakproof, O-Ring-sealed, spring-loaded self-closing
branch gauge tap.
