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 specic program periods. User can
enable or disable the remote sensor in the installer congura-
tion mode and also the outdoor temperature can be selected
to show on the display.
Once in the installer conguration 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.

Outdoor temperature range is -40 to 140

Indoor temperature range is 32

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 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.
