PROGRAMMING  
Weight of Remote Reading:  
Wired Remote Temperature Sensing  
When in view schedule mode the weight of the indoor remote  
sensor will be shown in the left actual temperature digits des-  
ignated as A2 (default for average weight), H4 (high weight)  
or L1 (low weight). The period (Morning, Day, Evening, Night)  
will also be shown to the right of the weight value in the actual  
temperature digits.  
One remote temperature sensor can be installed indoor or  
outdoor and connected to the thermostat by a maximum  
cable length of 100 meters (300 ft). Three terminals, +, S & -  
are provided on the terminal block to connect to the White-  
Rodgers standard wired remote sensor. This sensor will be  
read by the thermostat only when 24VAC is present.  
When used as indoor sensor, the readings can be weighted  
with the local sensor for specific program periods. User can  
enable or disable the remote sensor in the installer configura-  
tion mode and also the outdoor temperature can be selected  
to show on the display.  
When in view schedule mode, press  
and  
keys at the  
the same time to sequence the indoor remote temperature  
sensor weight from A2 to H4 to L1 and back to A2 for each  
of the program period times for each day. (The H4 weight is  
twice the weight of A2 and A2 is twice the weight of L1).

The local sensor may be disabled only if the indoor remote  
sensor is enabled and functional.  
If the indoor remote sensor is disabled or not functional, the  
local sensor will automatically enable and display in the run  
schedule mode.  
The actual temperature displayed in the run mode is the  
mathematical weighted sum of the two temperature sensors –  
local and indoor remote.

If the remote sensor is absent or not enabled then the actual  
temperature will be as measured by the local sensor.
