40 ETS Installation and Operation Manual
Calibrating the Actuator
NOTE: Each time the Actuator is assembled to the valve, the Actuator
must be calibrated.
1. Close the valve feeding the tempering valve HOT port.
2. Ensure the Actuator Manual Tab is in the Normal Operation position
(UP).
3. Remove the Actuator cover and ensure DIP switch 7 is in the ON
(MAN) position.
4. Change DIP switch 7 to the OFF (AUTO) position then back to the ON
(MAN) position.
The green and red LEDs start blinking, indicating calibration has started. The Actuator moves the valve
stem up and down. Calibration is complete when the green LED is steady‐on or blinking.
5. Replace the Actuator cover.
6. Open the valve feeding the tempering valve HOT port.
