A Note About Auto Changeover:

 

Auto changeover will switch between heating 
and cooling as needed. It is very important to 
make sure the cooling setpoint temperature is at 

least 3º above the heating setpoint temperature 

and that the heating setpoint temperature is at 

least 3º below the cooling setpoint temperature.

A Note About Programmable Fan:

The programmable fan feature will 
run the fan continuously during any 
time period it is programmed to be 
on. This is the best way to keep the 
air circulated and to eliminate hot 
and cold spots in your building.

Additional step if R251W indoor remote sensor is connected.

The 

T955W

 master thermostat will either average all sensors (system average) or only use 

one sensor for the system ambient temperature (priority).  The default setting is 

SYSTEM 

AVERAGE

, which means all sensors are averaged to create the system average ambient 

temperature reading.  The 

NEXT ZONE

 key can be pressed to change the priority.  

The system information area of the display shows the priority.

For Example:

 There is an 

R251W

 connected and it is named 

REMOTE 1

.  If the 

NEXT 

ZONE

 key is pressed until 

REMOTE 1

 is shown, then the 

REMOTE 1

 ambient temperature 

reading will be used exclusively for that time period.  All other sensors will be ignored.
