Actuator settings worksheet
Each actuator has four stages. For each actuator you are setting up you need to program the:
Minimum set point
Minimum position
Set point, differential, and position for stages 1 to 4
While the temperature is below the
minimum set point
, the actuator is closed. When the temperature
rises to the
minimum set point,
the actuator moves to the
minimum position
.
As the temperature rises, the actuator has four stages it moves through until it reaches its maximum
open position. This method lets you gradually open inlets instead of fully opening them when the
temperature rises above a single set point.
In other words, “when the temperature is here (
stage set point
), I want the actuator to start opening.
When the temperature reaches here (
stage differential
), I want the actuator to be at this position
(
stage position
) percent.”
