iO-WRP-S Satellite
Transceiver Module
1. The iO-WRP-S Satellite
Transceiver is mounted near or on
the outside of the outdoor unit. The
enclosure has a weather seal.
2. If 24VAC is not available from
the indoor unit, a transformer must
be installed in the outdoor unit to
provide 24 VAC. Refer to the
iO-WRP wiring diagram that best
suits the application.
Do not mount inside the
outdoor unit or inside any
metal enclosure as this will
greatly impede transmission
distance.
3. Make sure that all power is off before connecting wires to the Satellite transceiver.
4. After all wiring is completed, temporarily leave the access cover off and carefully attach
one of the antennas provided with the iO-WRP as illustrated.
Note: The iO-WRP-S Satellite Transceiver Module has a weather resistant gasket
seated in the enclosure. Make sure the gasket stays in place during installation.
There are two antenna gaskets included with the iO-WRP kit. One will be used on the
iO-WRP-S Satellite Transceiver Module during final assembly.
