Reverse-Action Air-Powered Thermostats
Also known as a two-pipe thermostat, this thermostat uses compressed air for power. Use when electricity is not practical or available for controlling your HVAC system. It is reverse action, so as the temperature goes up, the pressure in the system goes down.
Air consumption is measured in standard cubic inches/minute (scim).
The included universal fitting kit consists of a cover, mounting plate, dial stops, screws, tubing reducers, tubing, and mounting hardware. Internal filters are for the air connections and are included.
Calibration kit is sold separately and enables quick adjustment of thermostat.

Direct-Action Air-Powered Thermostats
Also known as a two-pipe thermostat, this thermostat uses compressed air for power. Use when electricity is not practical or available for controlling your HVAC system. It is direct action, so as the temperature goes up, the pressure in the system goes up.
