5000 What Sensors are
WIRED to your
System?
Check box on screen for each:
Indoor Air Temperature
Outdoor Air Temperature
Return Air Temperature
Discharge Air Temperature
None Both Yes Wired Sensors requires an EIM (Equipment
Interface Module). This ISU is only displayed if an
S1 or S2 terminal is available.
Click boxes on screen to select which sensors are
wired to the S1 and S2 terminals at the EIM.
The thermostat will not display Outdoor Air
Temperature if a wireless outdoor air sensor is
connected.
The thermostat will not display Indoor Air
Temperature if 6 wireless indoor air sensors are
connected. If you have a wired Indoor Air
Temperature network (1, 4, 9 etc), the thermostat
will allow up to 5 wireless indoor air sensors.
The thermostat will not display Return / Discharge
Air Temperature if there is no fan in the system.

Both Yes Wired Sensors requires an EIM (Equipment
Interface Module).
Select 10K or 20K based on the sensor installed.
Refer to resistance values below:
C7189U1005 = 10K ohm
C7772 = 20K ohm
TR21 = 20K ohm
TR21-A = 10K ohm (IMPORTANT - the TR21-A
must be used in combination with a TR21 sensor or
another TR21-A sensor for the thermostat to
calculate the correct indoor temperature reading).
See “Wiring guide — Wired Indoor Sensors”
beginning on page 119 for information on the
sensor type you should select based on how the
sensors are wired. For example, you would select
20K when you have two TR21-A (10K) sensors
wired in series.
