5.1 WEEKLY-PROGRAMMING DIGITAL
CHRONOTHERMOSTAT FOR THE REMOTE
CONTROL OF HOT AIR GENERATORS
THROUGH INTERFACE BOARD
The digital chronothermostat Brahma Kronos series
integrates the functions of room temperature control
and remote control of hot air generators 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 the parameters of more air generators, with
the related control boards connected in cascade, and
the eventual unlock.
It is possible to choose beetween different modes of
thermoregulation, even using an external probe
(connected to the hot air generator) 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 chronothermostat
(master) and the control board (slave) of hot air
generators takes place by means of a two-wire cable.
Particulary, the data, between the chronothermostat
and the control board of the first generator, are
exchanged
