SETUP
Detailed information about setup is available in the technical reference
manual and the online help for the System Access Point
(www.abb.com/freeathome).
1. To complete setup, you will need the ABB-free@home System
Access Point (SysAP) and a computer (tablet, laptop, or desktop
computer).
2. Remove the sticker from the device and place it on the Thermostat
Device Installation Plan that comes with the free@home System
Access Point.
3. Walls, ceilings, and electrical equipment can affect wireless
communication, especially steel reinforcements or other large metal
objects. Electrical devices that send high-frequency signals (such as
computers, wireless routers, audio systems, and video systems)
should be at least 3-feet from this device.
4. When first powered, the device is in discovery mode for 30 minutes.
This time period allows the SysAP to see and connect to the device.
During this time, the user can login to the SysAP and add the device
to the free@home network.
5. After 30 minutes, the device will automatically exit discovery mode. To
re-enter discovery mode, the user must turn the power OFF and back
ON again. This will place the device in discovery mode for another 30
minutes.
6. Once a device has been added to a network, it will no longer enter
discovery mode at power-up. To add the device to a new network, the
user must first force the device to forget its existing network by
resetting it back to factory settings.
5. Using a screwdriver, disconnect the wires and remove the old wall
plate. Wrap the wires around a pen to prevent the wires from falling
back into the wall, or tape the wires to the wall.

Follow these steps to reset:
A) Touch and hold power OFF button for at least 15-seconds, until
thermostat starts to reboot.
B) After rebooting, return to steps 3-4 of SETUP to connect the device to
a new network.
Install according to national and local electrical codes.
To clean, wipe with a clean damp cloth. DO NOT use any chemical
cleaning solutions.
