DIFFERENTIAL HEAT STAGES
In order to minimize erratic behavior of all
stages in heating mode 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 called 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 for heat stage
setting:
•
rotate the selector dial to position (8),
•
rotate the adjuster dial counterclockwise to
decrease the differential setting, and
clockwise to increase it.
The differential setting is displayed on the
MST-5.
