AIR INLET RELATIVE SET POINT
The air inlet relative set point establishes the
relative temperature at which the actuator
motor begins to open or close the air inlet baffle
board. This value is a temperature
difference
from the main set point.
The air inlet relative set point is adjusted in 0.5
degree increments from a minimum setting of
Opn, -0.9°F (-0.5°C) up to a maximum setting
of 30.0°F (16.0°C), Clo.
Adjusting the air inlet relative set point:
•
rotate the Selector dial to position (7),
•
rotate the Adjustor dial counterclockwise to
decrease the relative set point, clockwise to
increase it.
The air inlet relative set point is displayed on
the front panel.
CHAPTER 3 - USER’S GUIDE
Example:
A main set point of 70°F along with an air inlet relative
set point of 5°F is selected. When room temperature
reaches 75°F, and the air inlet timer delay has expired as
set by secondary function (8), the air inlet baffle board
begins to open for the period of time set by secondary
function (7). Due to a built-in 2 degree hysteresis, when
room temperature drops to 73°F, and the same timer has
expired, the air inlet baffle board begins to close for a
period of time set by secondary function (7).
