Entering Fan Program
The fan can be programmed to turn on at the beginning of a
period and remain on through the whole period. In RunSched
mode when the FAN switch indicates Prog Fan On the fan is
programmed to be on for the period.
1) Press System button to select either Heat or Cool.
2) Press Menu button and then press Fan button to the right
of the display.
3) The top of the display will show the day(s) being pro-
grammed. The fi rst period to be programmed will appear.
4) Press the Fan button to change from Auto to Prog.
5) Press the Fan button to the right of the display to change
to the next period.
6) Repeat steps 4 and 5 to program the fan for all periods of
the day.
7) Press Fan to advance to the next day of the week and
repeat steps 4 through 7 to program the fan for all days of
the week.
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 feet). Terminals +, S and - on
the terminal block allow connection of the remote sensor.
The thermostat must have 24 VAC Common connection to
terminal C for the remote sensor to operate. The remote sen-
sor can be enabled or disabled in the Installer/Confi guration
menu, item 16.
When remote sensor, Remote, is selected Off (factory de-
fault), no remote sensor is enabled. When remote sensor is
selected On, the next step is to select the remote as indoor,
Remote In, or outdoor, Remote Outdoor. If the remote is se-
lected as Remote In, an additional step will be to select if the
temperature shown on the display will be from the thermostat,
Loc On, or the remote sensor Loc Off.
In normal operation, when a remote sensor is enabled the
time digits of the display will alternate between the time and
the remote temperature for three seconds each. Above the
remote temperature will be Remote, for indoor sensor or
Outdoor Remote, for outdoor sensor. If the remote sensor is
an indoor sensor and the local display has been disabled, the
temperature displayed as the room temperature will be the
remote sensor temperature.

PROGRAMMING
Weighing of Remote Reading:
The thermostat will weight or average the temperature of the
indoor remote sensor with the local sensor in the thermostat
for each program period. The averaging will be active only
when the local sensor and the indoor remote sensor are both
functional and enabled in the Installer/Confi guration menu.
When the thermostat is in the Set Schedule mode, the weight
of the indoor sensor will be shown in the current temperature
digits of the display. The weight will show as A2 (average and
default), H4 (high) or L1 (low). Pressing the or but-
tons at the same time will change the weight for the program
period. The weight of the thermostat sensor is fi xed.
In normal operation of the thermostat, the current tempera-
ture displayed will be the weighted average of the local
sensor and the remote sensor using the formula (local sensor
weight x local sensor temperature) + (remote sensor weight x
remote sensor temperature) / (local sensor weight + remote
sensor weight).
Example: Local sensor temperature is 80° and the remote
sensor is 70°.
If weight is selected H4, the averaged temperature of 72° will
be displayed.
(1 x 80) + (4 x 70) / 5 = 72°
If weight is selected A2, the average temperature of 73° will
be displayed.
(1 x 80) + (2 x 70) / 3 = 73.3°
If weight is selected L1, the average temperature of 75° will
be displayed.
(1 x 80) + (1 x 70) / 2 = 75°
The example shows that the weight selected would prioritize
the overall averaged temperature between the two sensors.
The high weight selection caused the remote sensor to have
a higher infl uence in the calculated temperature average than
the local sensor and the low weight selection caused the
remote sensor to have less infl uence.
