When the temperature increases to above the setpoint, the circuit opens. When the reset lever is pressed after the sensed temperature decreases to approximately 20F° (11C°) below the setpoint, the circuit closes.
Refer to Figure 3 and Figure 4 for terminal identification and typical wiring connections.
Important: Only use the terminal screws furnished with the A25 (8-32 x 1/4 in. binder head). Use of other screws will void warranty, may damage switch terminals, and result in improper connections.
