Siemens 192-204 RM STAT D/N DSTPT 45/85F DA/DA

This 2-pipe thermostat automatically resets the room temperature setpoint during unoccupied hours, to help you save on your heating and cooling costs. Can be installed to replace outdated thermostats—of just about any brand—to provide proportional pneumatic valve and damper actuator control in large-volume heating and cooling applications. The dual-output design provides what is essentially 2 thermostats in one: one for heating and one for cooling, for outstanding flexibility and control. A 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.
