PROGRAMMABLE LED THERMOSTAT WITH WIFI CONNECTION
C800WIFI
OPERATION
The C800WIFI is a programmable LED thermostat with WIFI connection and integrated relay equipped with a temperature
and relative humidity sensor which allows the management of heating and cooling in flats.
Equipped with a “virtual” graphic interface that can be used via the APP, it optimises use of the room heating and cooling
system with Artificial Intelligence algorithms, with the aim of providing the best conditions of comfort with the lowest
possible consumption.
The temperature can be regulated in several ways:
■Directly from the programmable thermostat
■Via the Intelliclima+ APP
Below is a table showing the functions that can be managed via programmable thermostat and APP.
