Johnson Controls Two Stage Room Thermostat, SPDT (40 to 90F)

T25 thermostats are for line- or low-voltage service requiring accurate control of two operating functions. There are two stages of control for heating and cooling with automatic changeover on three- and four-pipe fan coil installations and similar applications. Typical uses are for compressor controls, relays, valves, fan coils, and other applications where low differentials and accurate sensing are required.
