Wired Remote Temperature Sensing
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 configu-
ration 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

Weight of Remote Reading:
When in view schedule mode the weight of the indoor remote
sensor will be shown in the left actual temperature digits
designated 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).

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.
