ECS 2M
As long as the actual temperature is below the main
set point, Fan 1 operates at the minimum speed set by
Fan 1 Minimum Speed (primary function 3). The Fan 1
duty cycle sets the percentage of time the fan is ON
versus the percentage of time the fan is OFF. The ON
time is entered as a percentage of the total time which
is known as the period.
The Fan 1 duty cycle is adjusted in 5% increments
from a minimum setting of OFF, 5%, 10% etc., up to a
maximum setting of ON corresponding to continuous
operation.
The period is fixed to 3 minutes.
Adjusting the duty cycle of Fan 1:
•
rotate the Selector dial to position (4),
•
rotate the Adjustor dial counterclockwise to decrease
the duty cycle, clockwise to increase it.
The duty cycle is displayed on the ECS.
Example: The duty cycle is set to 50%. As long
as the main set point temperature of the room
has not been reached, the fan operates at a
minimum speed for 1
½ minute and goes OFF
for 1 ½ minute.
