STAGE 1 LOW TEMPERATURE / PRESSURE 

ALARM 

 
 
This function establishes the temperature / 
pressure 

difference 

below the main set point 

that the room can reach before a low 
temperature alarm is signalled. When a low 
temperature / pressure alarm occurs the alarm 
relay is activated and the alarm LED lights on 
the CPS-2M. 
 
When a temperature probe is installed the low 
temperature alarm is adjusted in 0.5 degree 
increments from a minimum setting of -30.0°F 
(-18.0°C) to a maximum setting of 0.0°F (0.0°C) 
 
When a pressure probe is installed the low 

pressure alarm is adjusted in 0.01" H

2

O 

increments from a minimum setting of -0.10" 

H

2

O to a maximum setting of 0.00 " H

2

O. 

 

Adjusting the low temperature / pressure 
alarm 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 (7), 

•

rotate the Adjustor dial counterclockwise to 
decrease the setting, and clockwise to 
increase it. 

 
The low temperature alarm setting is displayed 
on the CPS-2M.
