a poor location for sensing temperature
or if you want to install the thermostat
in a separate room to prevent tamper-
ing. After installing and connecting the
remote sensor(s) to the thermostat, the
installer can enable each remote indoor
temperature sensor (A, B, and/or C).
The temperature at each remote sensor
can be displayed by pressing the light
button twice within one second with
the thermostat in program run or hold
mode. Temperatures at the outdoor and
indoor remote sensors will be
displayed with subsequent presses of
the light button in the following order
(if connected): outdoor sensor, sensor
L, A, B, C.
When operating with remote sensor(s),
the thermostat will calculate an
average of the sensed temperatures in
all enabled sensor locations (A, B, C
and/or L), then display the average
temperature as the room temperature.
During programming, you can also
assign each sensor different priorities
during different program periods. This
allows the system to maintain a
comfortable environment by giving
higher priority to occupied locations.
At the same time, efficient system
operation is enhanced by giving lower
priority to unoccupied locations.
EXAMPLE: Your location has the
thermostat in the office area and a
remote sensor in an assembly area. The
office has people working only during
the day shift, but the assembly area has
a day shift and night shift. During the
day, you want the office area to be
more comfortable so you give the
sensor in that area (the thermostat) a
HI priority during the OCCU period.
On the night shift, the office area is
vacant, but people are working in the
assembly area. You give the sensor in
that area a HI priority for the UNOC
period.
In the OCCU period, the office area
sensor will have more importance, so
the system will operate to keep the
temperature at the setpoint in that area.
In the UNOC period, the assembly
area sensor will have the higher
priority, so that area will be kept at the
setpoint temperature.
