For power, connect a 24 VAC, Class 2 only, trans-
former (see the diagram).
Connect the desired humidity output (0–5 VDC, 0–10
VDC, or 4–20 mA) from the THE-1002 to the control-
ler’s humidity input. (Set the controller’s pull-up
resistor accordingly.)
NOTE: The thermistor and the humidity output
have a common output signal ground.
Connect the temperature output (thermistor leads)
from the THE-1002 to the controller’s temperature
input. Make wire connections with either butt-splices
or solder. Using wire nuts is not recommended. (Set
the controller’s pull-up resistor accordingly.)
NOTE: The two-wire thermistor leads are polarity
insensitive.
NOTE: The relay module mounted inside the
electrical housing is hard-wired to the
sensing probe.
Do not attempt to lengthen
or shorten the prewired ribbon cable.
