STE-6000 Series Room Temperature Sensors 5 Applications Guide
Overview
Each STE-6012/6016 includes an
LCD display for the room tem-
perature and setpoint, which can
be toggled between Fahrenheit
(the default) and Celsius scales.
The sensor allows a user to adjust
the setpoint via the up and down
arrow buons on the front panel. If the system is in
standard mode (12 VDC applied to terminal D or the
green wire), pressing a buon will raise or lower the
setpoint. When either buon is pushed, the display
will toggle from room temperature to the setpoint.
The setpoint will increment or decrement (a degree
with each press) depending on the buon being
pressed. When the buon is released, the number
displayed is the new setpoint, and the display will
return to room temperature aer ten seconds. If the
system is in setback/setup (for heating/cooling) mode
(7.5 VDC applied to terminal D or the green wire),
pressing either buon selects override mode.
Controller Connection
For the STE-6012/6016, the controller will need signal
lines for two inputs (thermistor and setpoint), one
output (7.5/12 VDC supply), and common (ground).
Since each STE-6012/6016 has 0–5 volt DC outputs
for both the temperature and the setpoint lines,
turn o the corresponding 10,000 ohm pull-up
resistors on the controller board! Consult the
controller’s setup instructions for information on
turning o the pull-up resistors. For the other STE-
6000 series sensors, do not turn o the resistors on
the controller board as stated for the STE-6012/6016.
NOTE: For controller conguration instructions
for both WinControl and BACstage, see the
Controller Conguration section.
Fahrenheit/Celsius Display Selection
The STE-6012/6016 has an LCD display for showing
room temperature and setpoint. The display can be
toggled between Fahrenheit (the default) and Celsius
scales by performing the following procedure.
NOTE: Doing this erases any stored calibration
oset value (see below) and returns the
calibration to the default seing!
STE-6012/6016 Connection Configuration
1. Press and hold either the down or up arrow
buons for at least 20 seconds. The display will
toggle from one temperature scale to the other.
2. Release the buon.
NOTE: This seing is wrien to nonvolatile
memory and will be saved even if power to
the sensor is lost.
Temperature Calibration (Offset) Procedure
NOTE: The total oset value is limited to +/– 3
degrees from the default value.
The temperature value displayed by the STE-
6012/6016 may be ne-tuned if desired by
performing the following steps. The sensor must be
in a stable location and operating at least ten minutes
before calibrating. Hold an accurate thermometer
about an inch under the unit as a reference during
this procedure.
1. Click the down arrow buon to decrement the
setpoint to its lowest value, 40° Fahrenheit or
4° Celsius, then press and hold the down arrow
buon.
2. Aer holding the down arrow buon for about
ten seconds, the display will start ashing
the room temperature value and start an
approximately 15-second “exit calibration” timer.
NOTE: Entering the calibration mode erases any
previous saved oset value and will return
to the default seing.
3. While the room temperature value is ashing,
press the up or down arrow buon to modify the
room temperature value. Each press of the up or
down arrow buon will change the temperature
value by one degree.
4. The display will continue to ash for
approximately 15 seconds aer the last buon
press. Then the STE-6012/6016 will write the
modied value to memory and return to normal
operation.
NOTE: This procedure aects only the temperature
displayed on the LCD panel. It does not
aect the calibration or temperature value
in the controller. See also the WinControl
Thermistor Input controller conguration
instructions.
