Thermostat - Technical Description and
Features
The 24VAC iComfort Wi‐Fi
®
thermostat is an electronic communicating,
color display touchscreen and 7-day programmable thermostat. It stores
system parameters and settings in non-volatile memory (i.e., it retains data
when electrical power fails or is turned off).
The iComfort Wi‐Fi
®
thermostat can connect to online services via the
Internet through the homeowner's Wi-Fi access point. After online
registration is completed, the system may then be accessed by the
homeowner from anywhere using a remote Internet connection via computer
or personal communicating device.
Refer to page 37 for information on making connections to the thermostat.
