Pneumatic Room Thermostat, Reverse Acting @ 16 PSI / 25 PSI

Description
These thermostats provide proportional control of pneumatic valve and damper actuators in two-temperature (day/night, summer/winter) HVAC systems. Two highly sensitive bimetal elements, with feedback, and a pilot relay provide stability and accuracy.

Remote indexing is provided by dual main air supply levels. The first temperature control (right indicator for horizontal orientation, top for vertical orientation) occurs when the main air supply pressure is 16 psi. The second temperature control (left indicator for horizontal, bottom for vertical) is tripped when the main air pressure is 25 psi.

Models are available with either direct or reverse proportional action or a combination of actions. The throttling range is factory set and field adjustable. Setpoints are adjusted using sliders that can be locked or limited using setpoint stops (HFO-0027).

The thermostats require a scale plate assembly and cover. A variety of optional scale plates and covers are available for both models. See the Accessories section on the data sheet.
