Network Thermostat NetX NT-URS User manual

7. Strip 1/4 inch of insulation from three wires at the remote
sensor. Install the wires in the terminals using the table
below.
Cat5/Cat5e cable color code:
RS+V = Green with White Stripe
RS2 = Brown with White Stripe
RS1 = Green
Shielded cable color code:
RS+V = Color 1 in pair
RS2 = Drain wire
RS1 = Color 2 in pair
ANOTE: the wire color going to each terminal. The order
of the wires on the thermostat are not the same as the
sensor.
8. Connect the wires
on the thermostat
backplate to the
terminals labeled
RS1, RS2 and RS+V.
Make sure each
terminal on the
sensor is wired to
the terminal with
the same name on
the thermostat.
9. Set the DIP Switches on the bottom right of the sensor to
the appropriate sensor type.
10.Set the jumper to match the total number of sensors
directly connected to the thermostat; 1-2, 3-5, or 6+
sensors.
CWARNING: Do Not Count The Additional NT-URS
Sensors Used For Indoor Averaging.

Sensor Counting Example 1:
You are connecting an INDOOR sensor, OUTDOOR sensor,
AUX1, and AUX2. The sensor count is 4 and the correct
jumper conguration is the middle jumper 3-5.
Sensor Counting Example 2:
You are connecting 6 INDOOR sensors (Averaged) and one
INDOOR HUMIDITY sensor. The sensor count is 2 and the
correct jumper conguration it the top jumper 1-2.
Sensor Counting Example 3:
You are connecting 3 INDOOR sensors (Averaged),
OUTDOOR Sensor, AUX1, AUX2, AUX3, and a INDOOR
HUMIDITY Sensor. The sensor count it 6 and the correct
jumper conguration is the bottom jumper 6+.
11.Reattach the thermostat faceplate to the backplate. (See
your thermostat installation manual for instructions.)
For X-Series thermostats, the
remote sensor will display in
the upper left of the display.
Tap on the upper left of the
display to cycle through the
different connected sensors.
The names of the sensors
will display in the dot matrix
area of the display.
For UP32 and US32
thermostats, press the two
buttons on the right side of
the thermostat to activate
the secondary display for
remote sensors. Press the Up
or Down buttons to cycle
through the sensor types.
Rotate through indoor,
outdoor, humidity, and AUX
on the display. There will be
a value next to the icon for
the sensor type that has
been selected.
12.If there are no additional sensors to be added to the sensor
network, close the sensor case by hooking in the top, then
snapping it on the bottom.
USING NT-URS AS HUMIDITY SENSOR
Install the NT-URS sensor using the single sensor instructions.
The NT- URS can be congured as a dedicated humidity only
sensor. Reference the switch position in the diagram to the right.
You can view the humidity value in the thermostat’s web server
and on the thermostat faceplate, as described in
Step 11.
ADDING EXTERNAL SENSOR PROBES
Add the NT-RS-S or NT-FS to the NT-URS by connecting two
wires from the probe to the terminals designated 1 and 2 on the
NT-URS. (Connection to NT-RS-S shown below)
The wires can be connected with either polarity. Use 2-
conductor cable (22AWG minimum) with a maximum length of
300 feet (or 90m).
CIMPORTANT: If the NT-URS is initially congured with an
external probe and the probe fails or is disconnected, the NT-
URS will stop to reporting and the Diagnostic LED will
continually light until the problem is corrected.

Available Sensor Probes
from Network Thermostat
NT-URS AS AUX1, AUX2, OR AUX3 SENSOR
The NT-URS can report as as AUX1, AUX 2 or AUX3 sensor. In
this conguration, you can use either the internal temperature
sensor or an external probe.
When the NT-URS is initially detected by the thermostat, it will
check rst from the external probe connections, if no probe is
detected, the sensor will default to the internal temperature
sensor.
CIMPORTANT: If the NT-URS is initially congured with an
external probe and the probe fails or is disconnected, the NT-
URS will stop to reporting and the Diagnostic LED will
continually light until the problem is corrected.

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.
ANOTE:: Only ONE (1) NT-URS sensor congured as an
INDOOR sensor can be added in this manner. Additional
INDOOR sensors may be added by using the AVG terminals.
1. Wire the rst sensor using the single sensor instructions.
CCAUTION: 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.
X-SERIES 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
conguration. If the remains on, there is a communication
problem. Check wiring and x 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 x as
necessary. Cycle power cycle power and recheck the LED
status.
LED Slow Blink (Onboard Sensor Operation):
If the NT-URS is congured 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 congured 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 congured 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 congured 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 x
as necessary.
ANOTE: In this condition, the NT-URS will stop reporting until
the communication with the external probe is xed.
