HEATER/FAN 3 RELATIVE SET POINT

The Heater/Fan 3 relative set point is the
relative temperature at which Heater/Fan 3
begins to operate. This value is the temperature
difference from the main set point.
When a heater is connected,the relative set
point is below the main set point. When a fan is
connected, the relative set point is above the
main set point.
The Heater/Fan 3 relative set point temperature
is adjusted in 0.5 degree increments from a
minimum setting of -5.0°C (-9.0°F) to a
maximum setting of 10.0°C (18.0°F).
Adjusting the Heater/Fan 3 relative set point:
•rotate the selector dial to position (8),
•rotate the adjuster dial counterclockwise to
decrease the temperature setting, clockwise to
increase it.
•The relative temperature setting is displayed on
the 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 third fan is in use and the relative set point is
adjusted to 15°F. When the room temperature reaches
85°F the third fan begins to run.
