ECS 2M
In order to minimize erratic behavior of Heater/Fan 2
when room temperature is exactly at the relative set
point, the differential setting separates this ON/OFF
threshold into two: one ON threshold and one OFF.
This feature greatly reduces equipment wear.
The temperature difference between the two
thresholds is the differential.
The differential is adjusted in 0.5 degree increments
from a minimum setting of 1°F (0.5°C) to a maximum
setting of 6°F (3°C) degrees.
Adjusting the differential setting:
•
rotate the Selector dial to position (12),
•
rapidly rotate the Adjustor dial back and forth to enter
secondary function mode,
•
rotate the Selector dial to position (8),
•
rotate the Adjustor dial counterclockwise to decrease
the differential setting, clockwise to increase it.
•
The differential is displayed on the ECS.
