Welcome!
Thank you for your purchase of the Smart Forced Air Repeater product.
Introduction
The Repeater product is designed to perform three tasks. The first, and primary purpose of the
Repeater is to extend the wireless range of the system components. The second purpose of the
repeater is to behave as a temperature measurement backup for the system in the event all of the SFA
Thermostats stop reporting (their batteries all died). The third and final purpose of the Repeater
module is to facilitate firmware updates to the System.
Physical Installation
The SFA Repeater is as easy to install as it looks; simply find a central location in the house or office
building and plug it into the wall. It’s that easy!
System Linking
In most cases, the Repeater module will come already setup and linked into your system. You can verify
this by looking at the system information on one of your Thermostats; that menu should indicate if a
Repeater is linked into the SFA Comfort System.
If you do need to link the Repeater into the system for some reason, the process to is as follows:
 Enter linking mode on the Director or any of the Thermostats
 Press the link button on the bottom of the Repeater
That’s it!
Firmware Updating
If you are performing a firmware update, you will likely want to temporarily move the repeater to be
closer to a computer for ease of access to the USB port.
If all modules are not seen after moving the Repeater for the firmware update, you have a few options:
 Move the Repeater back to where it was and bring your PC (hopefully a laptop!?) to the
Repeater
 Bring the modules that can no longer be seen by the system closer to the PC (as long as it isn’t
the main Director module…)
 Purchase another Repeater to perform the update
