Actuators should match the type of controller from which they are controlled. Control circuits, especially direct digital, vary from product to product and from company to company.. Honeywell electric actuators provide instantaneous response to a demand signal, eliminating system non-linearity due to dead time. Additionally, since the actuator is electric, the costs associated with providing and maintaining a clean, dry air supply are eliminated.

Learn how to wire a Honeywell actuator valve with the help of a detailed diagram. Ensure proper installation and functionality of your heating or cooling system.. The actuators are operated by an spst two-position controller. When using an spst two-position controller, the actuator drives to the damper fully open position when controller contact makes and spring returns to the damper fully closed position when controller contact breaks. The actuator drops to holding power level on detection of stall, independent of hub position.
