CONFIGURATION
Comfort-Set II
Single Stage Models: Verify jumper wire W-22 on
the back of the thermostat (not the subbase) has
been clipped.
Multi-Stage and Heat Pump Models: Verify jumper
wire W-18 on the back of the thermostat (not the
subbase) has been clipped.
Comfort-Set III/Comfort-Set
90/90 Series
Single Stage Models(excluding touchscreen): Veri-
fy jumper wire W-922 on the back of the thermostat
(not the subbase) has been clipped. You must also
enable the remote sensor option in the Installation
Instructions, Conguration Menu.
Multi-Stage/Heat Pump and Touchscreen Models:
When installing a remote sensor you must enable the
remote sensor option in the Installation Instructions,
Installer Menu.
REMOTE SENSOR CALCULATED PRIORITY AVERAGE
Consult Maximum Sensing Locations Per Thermostat chart on page 6 to determine how many sensors a
thermostat will accept.
Tables 1-3 show how priority (LO, AVG, HI) eects the room temperature calculation. The example below
table three shows the calculation of each remote sensor and how it uses them to arrive at room tempera-
ture average.
The example below lists three sensors each with a dierent priority and room temperature. All three sensors
are combined in the calculation to display the average temperature. The priority multiplier shown in the
tables above causes a sensor with low priority to carry less weight in the calculated average. A sensor with
a HI priority setting contributes more to the calculated average. Assume that the building in which the
thermostat is located has three indoor remote sensors (SA, SB, SC) that have dierent room temperatures
(70, 75, 80). The calculated average will be displayed as the room temperature shown in the example below.
