2216-126 | Direct Acting, Three-Pipe, Day/Night Thermostat, w/o Dial Limit Stops, w/Remote | Schneider Electric

Direct Acting, Three-Pipe, Day/Night Thermostat, w/o Dial Limit Stops, w/Remote

Direct Acting, Three-Pipe, Day/Night Thermostat, w/o Dial Limit Stops, w/Remote and manual reset lever. These pneumatic room thermostats are designed for proportional temperature control of pneumatic valves and damper actuators to maintain room air temperatures in heating, ventilating, and air conditioning systems. Day 55-85°F Set point range, Night 50-80°F Setpoint Range.

Application

The 2216 Series Pneumatic Room Thermostats are designed for applications requiring separate control points due to varying occupancy or seasonal loads. They are direct acting and are particularly well suited to day/night control in buildings such as schools, hospitals, and shopping malls. These thermostats have a serrated thumb wheel for setpoint adjustment.
