The Heater/Fan 2 relative set point is the relative
temperature at which Heater/Fan 2 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 below the main set point. When a fan is being
controlled the relative set point is above the main set
point.
The Heater/Fan 2 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 18.0°
F (10.0°C).
Adjusting the Heater/Fan 2 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 room temperature reaches 65°F
the heater begins to operate.
A second fan is in use and the relative set point is
adjusted to 15°F. When room temperature reaches 85°
F the second fan begins to run.
