STE-6012/6016 Room Temperature Sensors

Controller Configuration
Overview
For an STE-6012/6016 sensor, the controller will need
two inputs (thermistor and setpoint), one output,
and a common (ground) signal lines.
Since an STE-6012/6016 sensor has 0–5 volt outputs
for both the temperature and the setpoint lines,
turn OFF the corresponding 10,000 ohm pull-up re
-
sistors on the controller board!
Consult the control-
ler’s setup instructions for information on turning off
the pull-up resistors. For the other STE-6000 series
sensors, do
not
turn off the resistors on the controller
board as stated for the STE-6012/6016.
See the relevant software section for controller
configuration instructions.

Supply Voltage
NOTE: The STE-6012/6016 is powered by the
controller on terminal D or the green wire.
With 7.5 VDC applied, the sensor is in
setback/unoccupied mode; with 12 VDC
applied, the sensor is in normal/occupied
mode.
Pressing the
Down
button momentarily
sends 0 VDC to the controller for a
SENSORON
signal on terminal C or
orange wire; pressing the
Up
button sends
greater than 5 VDC for a
SENSOROFF
signal.
Pressing a button raises or lowers the
setpoint voltage. When in unoccupied
mode, pressing either button selects
override mode (and “OVERRIDE” is
shown on the LCD display). “OVERRIDE”
will continue to be displayed until the
voltage is restored to 12 VDC.
To remove
“OVERRIDE” from the display at the end
of a timed override period, momentarily
change the voltage to 12 VDC and then

to the desired number of thermistor readings
averaged before displaying the result.
If the
override is being used,
Filter Weight
may need
to be reduced down toward 1 to ensure reliable
recognition of the button press, depending on
the controller.
NOTE: The Up and Down buttons need to be
pressed and held for at least a half a
second to be reliably recognized for
override mode.
