WEEKLY PROGRAMMING DIGITAL
CHRONOTHERMOSTAT WITH
REMOTE BOILER CONTROL
(OpenTherm

compatible) AND REMOTE
MANAGEMENT VIA GSM
APPLICATION
The digital chronothermostat
FIAMMA
OT11 series
integrates the functions of room temperature control and
remote control of home heating system in a single
interface, specially designed to make available all its
functionalities in intuitive mode.
Control of the heating system is complete, allowing to
manage advanced features such as solar thermal panels (if
supported by the thermoregulation board).
It is possible to choose beetween different modes of
thermoregulation, even using an external probe (connected
to the boiler) for climatic compensation.
Weekly programmation is particularly versatile because it
provides 4 temperature levels settable and no restriction
number of time slots per day, consisting of individual
intervals equal to a quarter of an hour and can be viewed
on the appropriate graph of the daily program.
The communication between the thermostat and the control
board of the boiler takes place by means of a two-wire
cable; the data are exchanged with the communication
protocol compatible OpenTherm ™ v3.0 Smart Power
Mode - Medium Power.
