HEATER / FAN 5 RELATIVE SET POINT
The Heater / Fan 5 relative set point is the
relative temperature at which Heater / Fan 5
begins to operate. This value is the tem-
perature
difference
from the main set point.
When a heater is being controlled the relative
set point is below the main set point. When a
fan is being controlled the relative set point is
above the main set point.
The Heater / Fan 5 relative set point
temperature is adjusted in 0.5 degree
increments from a minimum setting of -9.0°F
(-5.0°C) to a maximum setting of 30.0°F (16.0°
C).
Adjusting the Heater / Fan 5 relative
temperature:
• rotate the Selector dial to position (8),
• rotate the Adjustor dial counterclockwise
to decrease the temperature setting,
clockwise to increase it.
The relative temperature setting is displayed
ECS.
Example: The main set point temperature is adjusted
to 70°F. A heater is in use and the relative set point is
adjusted to -5°F. When the room temperature reaches
65°F the heater begins to operate.
A fifth fan is in use and the relative set point is
adjusted to 15°F. When the room temperature reaches
85°F the fifth fan begins to run.
