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 .
Once in the installer configuration mode, momentarily press 

the   or   touch key until display indicates 

Remote (at the

top left of the LCD) and OFF (default – in clock digits) .

Pressing   or   touch key will toggle the operation and 

display from 

Remote OFF to Remote On .

When 

Remote On is selected, press   key for the display to 

indicate Remote In (for indoor remote) .

The   or   keys will toggle the operation and display from 

Remote In to Outdoor Remote .

When any remote is selected the temperature will display in 

the clock digits for one second alternating with the current 

time for three seconds when in 

Run Schedule mode .

Outdoor Remote will indicate at the top left of display for 

outdoor remote reading . 

Only

 Remote will show at top left for indoor remote reading .

Sensing Range: 

Outdoor temperature range is -40 to 140

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 .

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) .
When 

Remote In is selected (with Remote selected to On),

press   key for the display to indicate the status of the local 

sensor 

LS On (default for thermostat local sensor operation-

al) . The   and   keys will toggle the function and display 

from 

LS (shown in actual temperature digits) and On (shown 

in clock digits) to

 LS OFF to designate the local sensor is 

disabled .
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 . 

(Outdoor remote sensor is not used for this computation) .

If the remote sensor is absent or not enabled then the actual 

temperature will be as measured by the local sensor .
