Unit installation

remote sensors 1 and 2. If they are detected by the TS16, they will show up in the calibration menu as
additional sensors to calibrate as C1 and C2. Note that if remote sensor with address 1 is attached it
replaces the internal sensor and becomes the “C1” sensor. See the remote sensor section for more
details.
When the desired sensor is selected in the setup menu, you can adjust its displayed temperature
calibration up or down 7 degrees by pressing the UP/DOWN buttons.
The calibration menu selections are:
C1 = calibrate internal sensor or remote sensor address 1 if attached
C2 = calibrate remote sensor address 2 (only shows up in menu if attached)
Remote Sensors
The TS16 Wall Display Unit has a remote sensor terminal block, J2, on the base for connection of a
remote temperature sensor. Remote sensors have an address that can be set to 1, 2, or 4. Without any
remote sensor attached, the WDU uses the internal sensor for the current temperature information. When
a remote sensor is attached, the WDU will detect it automatically and will use the remote sensor(s)
according to its address selection. Modes of operation are as follows:
Address 1: Use this remote sensor instead of the internal sensor. (becomes C1 in the calibration setup).
Address 2: Average remote sensor 2 with internal sensor or sensor address 1 if attached. (C2)
Table of Remote Sensor Functions and Sensor Addresses
Function Remote Addr 1 Remote Addr 2
Use internal sensor only No Yes
Used as remote sensor only Yes No
Average internal and one remote No Yes
Average two remotes (only 2) Optional with A2 Yes with A1
When averaging sensors are used, the average temperature is displayed on the WDU and reported to the
HVAC control unit. You cannot view an individual remote averaging sensor temperatures as the main
thermostat display or report individual sensor temperatures on the communication port. However, you can
check the individual sensor temperatures by going to the calibration setup menu and selecting the sensor
address. You can view the outside temperature by pressing both the UP/DOWN buttons simultaneously.
Display Lock
The TR16 WDU control buttons can be locked to prevent unauthorized changes in system operation from
the WDU. The display lock/unlock state can only be set by the “DL” network command. See the Serial
Protocol Manual for details on this command.
“CF” or “SF” Error Displays
If the WDU is not properly wired or if communications to the Control Unit is interrupted, the LCD display
will display “CF” to denote Communication Failure. Momentary display of “CF” caused by bad or lost data,
will clear automatically when data communication is restored.
If the “CF” continues to be displayed, check wiring for problems. A continuous “CF” display may indicate
a problem with the Control Unit or the WDU itself.
An “SF” display indicates a temperature sensor failure. If this is displayed continuously, the sensor is
failing to respond and must be replaced. This can also be displayed when attempting to view the outside
temperature if this sensor has failed or been disconnected.
