Cautions
When ordering valve body only: Use the rst six
positions to configure the valve.
When ordering actuator only: Use the last seven
positions to congure the actuator. Prex with
the letter A.
This feature is standard for spring return 3-way
actuators, and it must be included in the part number.
Should not be used with thermostats/controllers
unless they have a time-out feature.
