Temperature (SST) series
provides a traditional temperature sensor
solution and a wide array of options to
help you achieve comfort. The base model
SST contains a thermistor temperature
sensor. The CO
2
models feature a 0–2000
ppm 1–4 VDC CO
2
sensor. The OC models
feature a Passive Infrared Radiation (PIR)
motion sensor. The O models feature a
single button momentary contact override
button with backlight (on -L models) driven
from a universal output. The UD models
feature custom silicon rubber up/down
setpoint adjust buttons. The -S models
feature a 20k slider for setpoint adjust and
the -J models feature an RJ-11 jack for laptop
communications. Available in Warm Gray
(standard) or Solid White enclosure.

The CO
2
sensor employed in the
SST uses an ABC calibration
(Automatic Baseline Correction). The
calibration requires up to 3 weeks
to self-calibrate without interruption.
The calibration algorithm tracks the
lowest reading over a 7-day interval
to slowly correct long-term drift away
from acceptable fresh-air values of
between 400-450 ppm CO
2
. The
override and Up/Down buttons are
monitored by the controller using the
same input and same two wires as the
temperature sensor, in conjunction
with the Control-BASIC SENSOR-ON
and SENSOR-OFF functions.
