FAN 3 RELATIVE SET POINT
The Fan 3 relative set point establishes the
temperature above the main set point at which
Fan 3 begins to operate. The value is a
temperature difference from the main set
point.
The Fan 3 relative set point is adjusted in 0.5
degree increments from a minimum setting of
0.0°F (0.0°C) to a maximum setting of 30.0°F
(16.0°C).
Note: The differential on fan 3 is not
adjustable and the default value is set at 2°F
(1°C).
Adjusting the relative set point of Fan 3:
• rotate The Selector dial to position (6),
• rotate the Adjustor dial counterclockwise
to decrease the relative set point,
clockwise to increase it.
The Fan 3 relative set point is displayed on
the ECS.
Example: A main set point of 70°F along with
a Fan 3 relative set point of 8°F is selected.
When the temperature room reaches 78°F,
Fan 3 begins to operate.
