For the latest Instructions go to: WWW.SALUSINC.COM
To cover all SALUS Wireless Products without requiring customers to download unnecessary
documentation, the Wireless System Guide has been divided into 5 Modules. Module 1 is required for
all connected systems since it covers installation of the SG888ZB Gateway and the SALUS Smart Home
application. The remaining modules 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 Fan Coil 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.
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 Fan Coil system from anywhere via the SALUS Smart Home application from
a smart device or computer. If the connection to the internet is lost, the system continues to function
with the settings selected.

Step 1. Review and record the existing thermostat wiring conguraiton:
- Remove thermostat from wall plate to expose wiring terminals
- Take a photograph or note the wire colors and connections (see wiring reference table below)
- Attach wire labels to each of the wires
Remove Thermostat (if replacing existing thermostat)

Step 2. Label each wire when disconnecting them from thermostat terminals and remove the thermostat
mounting plate.
Paint the mounting surface, if desired, before mounting the new thermostat back plate to
ensure complete wall coverage.

Step 1. Install the Wiring Mount in the desired location using the junction box screws provided, making
sure the wires go through the center opening. An optional wall plate (sold separately) is available for
mounting to other junction box congurations.
Step 2. Connect the wiring to the ST100ZB Back Plate. Use the chart below to identify the desired
conguration. Schematic diagrams for 4-Pipe, 2-Pipe and 2-Pipe Applications are provided on the
following page.
