Delta Controls O3 Quick Start Guid

O3 Sensor Hub 2.0
Quick Start Guide
This guide describes how to install and set up the O3 Sensor Hub 2.0. To set up the hub, you will need an Android
or iOS device with the O3 Setup app installed. You can get the app from Google Play or the App Store.
Installation
Follow all applicable electrical codes and regulations. Connect to a Class 2 power source only.
Wiring guidelines
The sensor hub requires a 24 VDC power supply.
• For power and I/O wiring, use 22–14 AWG
2-conductor copper wire.
• For network cabling, use Cat5e or Cat6 cables.
Earth ground all devices in the same circuit at the
power supply. Up to 30 hubs can be daisy chained
using the ETH2 port as long as the distance between
hubs does not exceed 100 m (330 ft). A bypass
switch allows the hubs to relay data in a power failure
scenario. However, the maximum cable length is
reduced by 15 m (50 ft) for each bypassed hub.
Placement guidelines
You can mount the sensor hub to a ceiling tile, finished ceiling, or junction box.
• The hub should be mounted 2.4 to 4.6 m (8 to 15 ft) off the floor.
• For best performance, place the hub in center of the room. Try to keep it at least 2.1 m (7 ft) away from
windows or exterior walls.
• Choose a location where the motion sensor view is not obstructed by light fixtures, shelves, etc.
• Do not mount the hub next to hot or cold sources.
• Keep the hub at least 1.3 m (4 ft) away from ceiling diffusers and other sources of airflow.
Mounting the hub
1. If you are mounting the hub directly to the ceiling, cut
a hole 32 mm (1¼ in.) in diameter and pull the wires
through the hole.
2. Remove the backplate from the hub by twisting it
counter-clockwise.
3. Pull the wires through the hole in the backplate.
4. Mount the backplate to the mounting surface using
M4 (#8) screws.
5. Connect the power wires, I/O wiring (if present), and
Ethernet cables to the sensor hub.
6. Re-attach the hub to the backplate. Line up the tabs on
the hub with the notches on the backplate, hold the hub
firmly against the backplate, then twist clockwise.
7. Turn on power to the hub. The light ring plays a blue swirl pattern while the hub is booting. A power-on self-
test runs next (green = OK, red = sensor failure, blue = Bluetooth error, orange = network connection issue).
When the light ring turns off, the hub is ready to use.
