4.3.3. Smart Sensors (for zoning applications)
Any zone may use a Smart Zone Sensor (SYSTXBBSMS01). It provides
a temperature display and buttons to adjust the desired temperature in
that zone only. It also displays outdoor temperature and indoor humidity
sensed at the Zone 1 Evolution Connex Control. Only one Smart Sensor
may be used per zone. They cannot be averaged like Remote Room
Sensors. If a Smart Sensor is used in a zone, one wired Remote Room
Sensor may also be used in the same zone. The wired Remote Room
Sensor has priority over the Smart Sensor; the Smart Sensor will display
the wired Remote Room Sensor temperature, when used.
NOTE: Smart Sensors must be addressed to identify which zone it will
control. See Smart Sensor Installation Instructions for details.
4.4. Wiring Considerations
Ordinary thermostat wire is recommended. See Shielded Wire and
Communication Bus Configuration Section for notes on shielded wire.
Continuous wire lengths over 25 ft. should use 18 AWG wiring.
NOTE: ABCD bus wiring only requires a four-wire connection;
however, it is good practice to run thermostat cable having more than
four wires in the event of a damaged or broken wire during installation.
