Desert Aire dehumidifiers ordered with the zone reset option are supplied with a
remote room sensor. Up to four of these sensors may be wired to the system.

This wall-mountable display is an IP30 rated device. Operating conditions must be
between 32.0° F and 120.0° F and less than 85% RH. The controller’s RS485 serial
interface communicates via three-way plug-in terminals. Install a twisted pair plus
shielded cable, 20-22 AWG. Total length of the network must not exceed 1,500
feet. The capacitance between the wires must not exceed 90 pF/M. (See your
wiring schematic for connection details.)
CAUTION:
Undersized wiring will cause inaccurate sensor readings. Do not run
sensor wiring adjacent to, OR in the same conduit as, wires carrying more than 24 VAC.
These remote devices require a separate 24Vac 50/60HZ 1.5VA power connection.
Provide a dedicated 250 mAT fuse for each sensor. Use a class 2 safety
transformer with a minimum rating of 4VA. If the sensor is wired to F1 and F2 of the
dehumidifier control panel terminal, G0 must be connected to F2.
