MULTIPLE INDOOR SENSOR
CONFIGURATION
You can connect up to six (6) NT-URS sensors to provide
INDOOR temperature averaging in a large area or several
zones being controlled by the same system. Maximum
distance for all sensors is 300 ft. (90m). Follow the instructions
and diagrams to connect the additional INDOOR sensors.
A
NOTE:
: Only ONE (1) NT-URS sensor configured as an
INDOOR sensor can be added in this manner. Additional
INDOOR sensors may be added by using the AVG terminals.
1. Wire the first sensor using the single sensor instructions.
C
CAUTION:
Make sure there is no power to the sensors
by removing the thermostat from its backplate.
2. Connect wires to each additional sensor in the following
manner.

UP32/US32
3. Set #SENSORS jumper to 1-2 for
ALL
additional sensors
used for averaging.
4. Reinstall the thermostat faceplate on to its backplate. Check
proper operation by watching the LED blink pattern as
outlined in the
LED Status
section. Repeat for each sensor.

LED STATUS
The NT-URS includes a Diagnostic LED that can help you
troubleshoot your installation and sensor operation.
LED Off:
LED OFF indicates no power to the NT-URS or thermostat.
Check wiring of your sensor and the thermostat for problems.
Fix as necessary.
LED On Solid During Power-Up:
On power-up the LED will turn on solid until the NT-URS
successfully communicates with the thermostat. If the
connection is successful, the LED will blink according to its
configuration. If the remains on, there is a communication
problem. Check wiring and fix as necessary.
LED On Solid After Power Up:
If the NT-URS loses connection with the thermostat for 60
seconds, the LED will turn on solid. Check the wiring and fix as
necessary. Cycle power cycle power and recheck the LED
status.
LED Slow Blink (Onboard Sensor Operation):
If the NT-URS is configured to use its internal sensor
(temperature or humidity) the LED will blink each time the
thermostat requests data. This occurs approximately every 16-
20 seconds.
LED Double Blink (Onboard Sensor Averaging):
If the NT-URS is configured to INDOOR temperature and an
additional sensor is connected to the AVG connection, the LED
will blink twice each time the thermostat requests data. This
occurs approximately every 16-20 seconds.
LED Triple Blink (External Probe Operation)
If the NT-URS is configured to use an external probe
connected to the 2-screwless terminals, the LED will blink three
times the thermostat requests data. This occurs approximately
every 16-20 seconds.
LED Fast Continuous Blink (Lost External Probe)
If the NT-URS is configured to use an external probe and the
NT-URS loses communication with the probe, the LED will
continually blink fast. Check wiring and external probe and fix
as necessary.
A
NOTE:
In this condition, the NT-URS will stop reporting until
the communication with the external probe is fixed.
