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.
