STAGE 5 RELATIVE SET POINT
The stage 5 relative set point is the relative
temperature at which Heater/Fan of stage 5
begins to operate. This value is the
temperature
difference from the main set
point.
When a heater is being controlled, the relative
set point is bellow the main set point. When a
fan is being controlled, the relative set point is
above the main set point.
The stage 5 relative set point temperature is
adjusted in 0.5 degree increments from a
minimum setting of -15.0°F (-10.0°C) to a
maximum setting of 32.0°F (16.0°C).
Adjusting the Stage 5 relative temperature:
•
rotate the selector dial to position (5),
•
rotate the adjuster dial counterclockwise to
decrease the relative set point, and
clockwise to increase it.
The stage 5 relative set point is displayed
MST-5.
Example: The main set point temperature is adjusted
to 70°F. A heater is in use and the relative set point is
adjusted to -4°F. When room temperature reaches 66°
F, the heater begins to operate.
A fan is in use and the relative set point is adjusted to
8°F. When room temperature reaches 78°F, stage 5
begins to operate.
