4. If the address DIP switches are set to the correct
positions and the temperature sensing system is
ready for operation or testing, set the
POWER
DIP switch to the ON position (Figure 5 or
Figure 6).
5. Align the tabs on the bottom edge of the transmitter
mounting base with the slots on the bottom edge of
the transmitter housing, and rotate the transmitter
assembly onto its mounting base. (Reverse the
procedure shown in Figure 2.)
6. Use a 1/16 in. (1.6 mm) Allen wrench or
Johnson Controls T-4000-119 Allen-Head
Adjustment Tool to tighten the tamper-resistant
set screw and secure the transmitter assembly
onto its mounting base (Figure 2).
Press and release the signal test button on the
FX-WRZRMT10K-0 Wireless Remote Temperature
Transmitter (Figure 1) to initiate a signal strength test
with the associated FX-ZFR1811 Router or
FX-WRZ7850-0 Receiver. The signal strength is shown
on the LCD on the face of the transmitter (Figure 8).
An optional FX-WRZSST-110 Wireless Sensing
System Tool can also be used with the
FX-WRZRMT10K-0 Wireless Remote Temperature
Transmitter prior to installation as a site survey tool, to
determine potential installation locations for system
devices and to determine the wireless signal strength
between the system devices in the application.
Refer to the
FX-WRZSST-110 Wireless Sensing
System Tool Installation Instructions
(Part No. 24-10563-20)
for more information on
testing signal strength.
Additional Product Information
Table 2 includes Negative Temperature Coefficient
(NTC) thermistor sensor temperature/resistance
response characteristics for the TE-6300 Series
Temperature Sensor. The values included in this table
can be used to verify the accuracy of the temperature
sensor in the field.
Note: If another manufacturer’s 10k ohm thermistor
sensor is used with the FX-WRZRMT10K-0 Wireless
Remote Temperature Transmitter, the values for the
temperature/resistance response characteristics may
be different than those indicated in Table 2 for the
Johnson Controls TE-6300 Series Temperature
Sensor. This difference may cause the transmitter to
read temperatures incorrectly.

Digital Readout for 104°F
Note: Digital readouts
above 99.9°F are whole
numbers (no decimals),
where the first and second
digits are full size and the
third digit is half size.
Digital readouts for Celsius
temperatures are normal
size and include decimals.
