ZONE 2 DIFFERENTIAL

 

 
 
 
The differential minimizes erratic behavior of 
the actuator motor when the room temperature 
is exactly at the main set point. The differential 
setting is above the set point when curtains are 
closing, and below set point when they are 
opening. This feature, which greatly reduces 
equipment wear, represents the inactivity zone 
for the CPS-3M, that is if the main set point is 
reached. 
 
The differential is adjusted in 0.5 degree 
increments from a minimum setting of 0.0°F 
(0.0°C) to a maximum setting of 6°F (3°C) 
degrees. 
 
 

Adjusting the differential setting for zone 2: 

 

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 (2), 

rotate the adjustor dial counterclockwise to 
decrease the setting, and clockwise to increase 
it. 
 
The differential setting is displayed on the CPS-
3M.
