INTRODUCTION
The TBX Thermometer / Barometer System is comprised of a microprocessor
based controller and a step-motor driven movement that provide accurate,
completely automatic indication of Temperature or Barometric Pressure.
Completely automatic operation - No user intervention required
Maintenance free
Automatically resets after power failures to ensure correct readings
For indoor or outdoor use - Protected to Ip67

OPERATION
The TBX Controller is setup and calibrated at the factory to provide years of
maintenance-free, accurate temperature / barometric pressure indication. After
installing a Thermometer or Barometer per the setup instructions provided, the unit
operates as follows:
TBX reads Temperature Sensor or Barometric Pressure Sensor
TBX converts reading to a known angular pointer position on display dial
TBX sends command signal (via RS-485) to movement to drive pointer to correct
position
TBX repeats this process continually to constantly update pointer position as
required
After power outage, TBX will command movement to reindex (go to “HOME”
position) and then bring pointer back to correct position to ensure accuracy of
display

DEVICE ADDRESSES
Any Thermometer / Barometer movement that is connected to the TBX
Controller will have a unique address such that the TBX Controller can send different
commands (via RS-485) to specific movements depending upon their address. In
this way, one TBX Controller can control a Thermometer and Barometer
simultaneously (or two Thermometers with different temperature scales, etc.). The
status LED’s inside the TBX indicate what addresses are being used by movements
that are connected to the controller. Not only does this indicate that a movement is
connected (helpul when troubleshooting) but it also tells what type of movement is
connected. Using the following table it is possible to determine what type of
movement is connected to the control based upon its address.

TROUBLESHOOTING
“MY THERMOMETER / BAROMETER IS NOT CORRECT”
!Pointer still moves, but readings shown are not correct
1) Send the Pointer to “HOME” position
Inside TBX Controller, press “HOME” button once
Look at dial: Pointer should point to lowest reading on dial and stop (ex. -20 F)
If Pointer is NOT pointing to lowest reading on dial, it must be adjusted manually
Remove pointer from movement shaft and follow instructions in “Quick Start
Guide” for proper setup of Thermometer / Barometer systems
If Pointer IS pointing to lowest reading on dial, see “Calibration Procedure” on
Page 11 to calibrate the thermometer
!

~
“MY THERMOMETER / BAROMETER DOESN’T MOVE”
1) Check AC Power Input
Inside TBX Controller, is POWER LED illuminated?
If not, have an electrician check circuit breakers or building electrical supply
2) Check Temperature Sensor (for Thermometer Systems only)
Inside TBX Controller, is Temperature Sensor connected?
If not, reconnect sensor and hit “HOME” button once to re-index the thermometer
WAIT 60 Seconds, then hit “HOME” button again to resume operation
Is Pointer showing correct temperature?
If not, contact Electric Time Company for service
3) Is movement(s) connected to TBX Controller?
Inside TBX Controller, are any address LED’s illuminated (numbers 1-16)?
If not, check all wiring connections to movement
If all wiring connections are OK, contact Electric Time Company for service

TROUBLESHOOTING
CALIBRATION PROCEDURE
If the thermometer or barometer is operating, but does not indicate the correct reading,
the following calibration procedure can be used to set the thermometer/barometer to the
correct reading
CAUTION: The following calibration procedure requires opening the TBX Controller
while it is powered. Although the supply voltage to the controller is typically only
24VAC or 24VDC, this procedure should only be performed by a qualified technician
or electrician.
With the thermometer operating normally, remove the cover to the TBX Controller
Housing
At the top edge of the circuit board near the middle of the board is a vertical row of
2-pin headers (identified as JP4 on the circuit board) and labeled THERM, BARO,
CLEAR, & PARK
There is a small black jumper located in the PARK position
Move this jumper to the THERM or BARO position to enter calibration mode for
either a Thermometer or Barometer respectively
With the jumper in place, locate the adjustment potentiometer (identified as R39
on the circuit board) and labeled ADJUST
Using a small screw driver, slowly turn the ADJUST potentiometer
The pointer on the Thermometer / Barometer dial will move as the potentiometer
is turned
Turn the potentiometer until the pointer indicates the correct temperature or
barometeric pressure as required
When the pointer indicates the correct reading on the dial, remove the jumper
from the calibration position and return it to the PARK position for storage
