Product Details

This dual-temperature, dual-dial pneumatic room thermostat provides individual day/night, or 2 set point temperature control in HVAC applications, while helping you save money on energy and equipment costs by placing minimal demand on heating and cooling apparatus. Lower and upper set points are independent of one another—a change in one does not affect the other, giving you the flexibility to maximize energy savings and comfort at the same time. Also features an additional output air terminal, which can be used as an on-off switchline pressure. A standard manual indexing switch exhausts pressure and restores thermostat day operation without affecting other system thermostats.
