iO-WRP WIRELESS RELAY INSTALLATION, OPERATION MANUAL
iO-WRP WIRELESS RELAY Installation, Operation Manual 915MHz INTRODUCTION The iO-WRP wireless relay system consists of 2 units; an iO-WRP-B Base Transceiver and an iO-WRP-S Satellite Transceiver. The base transceiver is equipped with 3 digital input channels and 1 relay output channel. The satellite transceiver has 1 digital input and 3 relay output channels. The digital inputs are compatible with 24VAC HVAC systems. The outputs are switched through onboard relays.
4. Make sure 24VAC power is off before connecting wires to the base transceiver. 5. After all wiring is completed, temporarily leave the access cover off and carefully attach one of the antennas provided with the iO-WRP transceivers. iO-WRP-S Satellite Transceiver Module Antenna Gasket 1.

TEST, CHECK AND START-UP 1. Once all wiring is completed, apply 24 VAC to both transceivers. 2. Turn the thermostat or control device off so that no signal is sent. LED BEHAVIOR IN PAIRED MODE GREEN - When 24 VAC is applied, each transceiver LED will be solid green. RED - Each module LED will flash red briefly when a data message is sent and go solid red up to 10 seconds until transmission is confirmed. 3.
UNPAIRING TRANSCEIVERS Unpairing a base and satellite transceiver is accomplished by holding down the button while applying 24VAC and continuing to hold the button down for about 5 seconds. While the button is held down, the LED will flash between red and green 5 times per second. Once the unpairing process is complete, the LED will flash as described in the pairing section.
