Setpoint Adjustment: Loosen the cover screw (Figure 1) and remove the cover. Adjust the setpoint by rotating the adjusting screw. When adjusted, re-install the cover. Tighten cover screw.
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 20F° (11C°) below setpoint. Press the reset lever to reset the A25 (closing the circuit).
