STAGE 1 DIFFERENTIAL
In order to minimize erratic behavior of Heater /
Fan 1 when ambient 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 0.5°F
(0.5°C) to a maximum setting of 10°F (5°C)
degrees.
Adjusting the differential setting:
•
rotate the Selector dial to position (2),
•
rotate the Adjustor dial counterclockwise to
decrease the differential setting, clockwise
to increase it.
The differential setting is displayed on the
MST-1.
