Maintenance
Careful installation will also ensure long-term
reliability and performance. Remove dust as neces-
sary from holes in top and bottom. Clean with a soft,
damp cloth and mild soap.
More Information
For controller configuration of the
humidity input, see the relevant
documentation for the controller
and software. For controller con-
figuration of the thermistor input
as well as mounting considerations,
troubleshooting, and other informa-
tion, see also the relevant sections
in the
.
For THE-1102 specifications and
accessory information, see the

the THE-1102 with the REE-2002,

NOTE: The early version of the THE-1102 had
terminals marked A through F.
For power, connect the + side of a regulated 10–15
VDC power supply to Terminal “D” and the – side to
“F” (see the terminal diagram).
NOTE: Signal ground and power ground are
connected together internally.
Connect the temperature output (10K thermistor
across Terminals “A” and “C”) to the controller’s
temperature input. (Set the controller’s pull-up resis-
tor accordingly.)
Connect the humidity output (0 to 5 VDC across
Terminals “B” and “C”) to the controller’s humidity
input. (Set the controller’s pull-up resistor accord-
ingly.)
NOTE: The internal thermistor and the 0 to 5 VDC
humidity output have a common signal
ground.
Alternately, use an REE-2002 (shown here but pur-
chased separately). See the
for additional information about power and
humidity output options.
