iO-WR WIRELESS RELAY
Installation, Operation Manual

Introduction

The iO- WR wireless relay system consists of 2 units; an iO-
Transceiver Moduleand an iO-
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 24
switched through onboard relays. When properly installed and configured, the
iO- WR system provides reliable wireless communication between two devices.
Although the iO-
unimpeded communication between the two devices can vary depending on
barriers created by interior and exterior walls and their material composition.
The iO- WR communicates on the 915

Each transceiver is equipped with a bi-color
operational state. The transceivers also have a momentary pushbutton which is
used to "pair" two units together, "unpair" previously paired units, or force a data
transaction.
NOTE: The wireless relay transceivers are already factory paired and will
begin to communicate once 24 volts is applied to each unit.

3. Use only 18-gauge solid (not stranded) thermostat wire. When connecting
wires to the transceiver terminals, strip approximately 1/4" of insulation and push
wire into designated terminal. Do not over-tighten the mounting screws.

1.Mount the iO-
Transceiver on a non-metalic
surface in a location that allows
access to the thermostat wiring
at the indoor unit.
Do not mount inside the unit
cabinet or inside any metal
enclosure as this will greatly
impede transmission distance.
