Honeywell LP907A1002 Air Stream Thermostat (40F to 140F)

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. The LP907A Airstream Insertion Thermostat is most commonly used as a discharge controller in unit ventilator applications. Other applications include a limit device when used with other controllers and as a proportioning type controller for pneumatic valves and dampers in fan room applications. When used as limit controllers, they provide a “submaster action” caused by overcontrol during light load conditions.

Features: Rod and tube insertion sensing element. Wide throttling range. Gage tee and tank valve facilitate checking line pressures.
