Product Details

2-pipe thermostat can be installed to replace outdated thermostats—of just about any brand—to provide proportional single-output pneumatic valve and damper actuator control in large-volume heating and cooling applications. The built-in field-adjustable limit stops let you make adjustments on the fly, while the test port allows fast check of output pressure without removing the cover (cover not included). Included wall plate and screws let you connect to a variety of rough-in boxes.
