To cover all SALUS Wireless Products without requiring customers to download unnecessary
documentation, the Wireless System Guide has been divided into 5 volumes. Volume 1 is required for
all wireless systems since it covers installation of the SG888ZB Gateway and the SALUS Smart Home
application. The remaining volumes are specic to a particular group of controls.
Below is a description of several icons used to direct the reader’s attention.
Special Attention Boxes
This manual uses special attention icons to alert the reader of important safety concerns, information
important to reliable operation of the controls or helpful installation/setup information.
Safety:
Indicates a condition which may cause severe personal
injury, death or major property damage
Important Information:
Indicates information which requires special attention
for correct operation of the control
Your Benet:
Indicates helpful installation or setup information

System Overview
SALUS connected HVAC control systems use Zigbee-based communications protocol to provide a
universal language for smart components to work together seamlessly and securely with an internet
connection. If the internet connection is interrupted or dis connected, the HVAC component will
continue to operate together.
Module 4 – Wireless HVAC Thermostats
Introduction
Section 1
By connecting the SG888ZB Gateway to your home network, the system is connected to the worldwide
web. Monitor or adjust your HVAC system from anywhere via the SALUS Smart Home application. If the
connection to the internet is lost, the system continues to function with the settings selected.
