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 one of the S1-S4 terminals is
available.
Click boxes on screen to select which
sensors are wired to the S1-S4 terminals at
the EIM.
The thermostat will not display the Outdoor
Air Temperature option at ISU 5000 if a
wireless outdoor air sensor is connected.
The thermostat will not display the Indoor
Air Temperature option at ISU 5000 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 the Return /
Discharge Air Temperature option at ISU
5000 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 154 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.
