Setpoint Adjustment: Adjust the A25 setpoint by rotating the setpoint knob (Figure 1). The setpoint is displayed in the setpoint window.
Test Procedure:
To test (trip) the A25: Raise the temperature at the sensor above the setpoint or lower the setpoint below the ambient temperature. The control should lockout (trip).
To reset after test: Lower the temperature at the sensor to 20F° (11C°) below the setpoint or raise the setpoint to 20F° (11C°) above the ambient temperature. Press the reset lever. The A25 should reset (closing the circuit).
Reset Procedure: Verify that the temperature has dropped to 20F° (11C°) below setpoint. Press the reset lever to reset the A25 (closing the circuit).
