Pneumatic Thermostats

832/D

The single setpoint, direct acting thermostat provides gradual acting pneumatic room temperature control for heating and cooling applications. The 832 D Thermostat is ruggedly constructed for dependable, long-term service.

 

 

CTC-1611/1612

These thermostats are designed for proportional control of pneumatic valve and damper actuators used in HVAC systems. A highly sensitive bimetal element with feedback is used for accuracy and stability. An external restrictor is required in the supply line. Select the model for direct or reverse...

CTC-1621/1622

The CTC-1621/1622 thermostats are designed for proportional control of pneumatic valve and damper actuators in HVAC systems. They utilize a highly sensitive bimetal element with feedback and a pilot bleed relay for accuracy and stability. Select the model for direct or reverse acting...

CTC-1631/1632

The CTC-1631/1632 thermostats are designed for proportional control of pneumatic valve and damper actuators used in HVAC systems. A temperature span may be set so the system uses no energy for either heating or cooling between selected setpoints. For accuracy and stability, they utilize highly...

CTC-1640 Series

The CTC-1640 series is designed for proportional control of pneumatic valve and damper actuators used in two temperature HVAC applications. These may include day/night, summer/winter or other. For accuracy and stability, they utilize two highly sensitive bimetal elements with feedback and a...

CTC-5500 Series

The CTC-5500 series room thermostats are designed for use in HVAC systems for the control of pneumatic valves and damper actuators. They are fully proportional, two-pipe relay thermostats which require main air at the thermostat. Offering acute accuracy, small size, and simplistic design, they...

ICD-192

Providing proportional single output, single setpoint, 1-pipe for low air capacity or 2-pipe for high air capacity pneumatic room temperature control, the 192 S Powerstar Single Setpoint Pneumatic Room Thermostat is the most economical model. Refer to the Retroline® Retrostats on page A-15 to...

ICD-192 Kit

The Powerstar Retroline Retrostat Pneumatic Room Thermostat converts most existing pneumatic room thermostats to a Powerstar 192/194 direct or reverse acting, 2-pipe, single or dual setpoint unit. Day/Night or Heat/Cool Retrostat is factory calibrated to match the appropriate changeover pressure...

LP907

One-pipe, single setpoint, pneumatic thermostat used to provide proportional control of pneumatic valves and damper actuators in heating and air conditioning systems. Commonly used as discharge controllers for unit ventilators.

LP916

Two-pipe, single temperature, unit mounted, remote bulb pneumatic thermostat used to provide proportional control of pneumatic valves and damper actuators in heating and air conditioning systems.
