ZONE 2 ROOM TEMPERATURE 

DISPLAY 

 

 

This position displays the actual room 
temperature (zone 2). When monitoring only 1 
zone, the displays shows three horizontal bars 
for this position. 
 
Room temperature is displayed to the nearest 
0.1 degree from a minimum display of 42.0°F 
(5.5°C) to a maximum display of 111°F (44.0°C). 
If temperature is lower than 42.0°F, 

Lo

 is 

displayed. If temperature is higher than 111°F, 

Hi

 is displayed. 

 
 

Viewing the room temperature: 

 

•

rotate the selector dial to position (1) 

 
The room temperature for zone 2 is displayed on 
the CPS-3M.
