Multiple Thermostats - Group ID
Multiple S40 thermostats in a home can be assigned to a group (up to nine
groups with up to ve (5) thermostats in each group). All thermostats in a group
can communicate with other thermostats in the same group over a single 2.4
GHz Wi-Fi network.
IMPORTANT
If the home will have multiple S40 thermostats then they all MUST be on the
same 2.4GHz Home Wi-Fi network in order to communicate with each other.
Do not use 5 GHz.
All S40 thermostats can be grouped together. If you have a S30 or E30, they
will NOT be appear on the S40 thermostat.
Default Group ID 1. Range is 1 to 9.
NOTE: If a thermostat is set to Group 0, then there is no connectivity with
another S40 thermostat within the home on the same 2.4Ghz Wi-Fi
network.
Group IDs can be changed by going to Settings > Advanced Settings > View
Support Service Control Center > Equipment Settings > Thermostat and
look for Group ID.
Restarting thermostat
To restart the thermostat, go to > Settings > Advanced Settings > View

Commissioning Using the Thermostat
The following procedures are written for commissioning the system using
the Thermostat interface. When power is rst applied to the system all
communicating devices attached to the system (air handler or furnace, outdoor
unit, PureAir S or zoning control) will automatically be congured using optimal
factory default settings based on system type, capacity and other conguration
considerations.
NOTE: If there is a PureAir S Air Purication System installed, during
commissioning the blower will turn on and run at three different CFM
settings for the PCO lter calibration to take place. This may be well
in advance before the display is fully up and running. This is a normal
process. The blower may run as long as ninety (90) seconds at each
CFM setting to complete the lter calibration.
1. Apply power to the thermostat.
IMPORTANT
If after applying power to the thermostat a “System Under Test” screen appears,
it could indicate either the system is under reconguration or is unable to
communicate with the indoor unit. Check wiring connections between the
thermostat wall plate and indoor unit for loose or incorrect connections.
2. A Welcome screen will appear. Select the desired language to be used.
Options are English, Franҫais and Español. Select the right arrow to

Select option 1 and select the right arrow to continue.
