BASE FUNCTION
FIRST LEVEL MENU
When the chronothermostat is connected to a
thermoregulation board, the following screen appears on
the display.
If the thermoregulation board is not compatible, you will
receive an error message.
In the figure the main screen.
Above are shown the day of the week and the current time,
these indications are intermittent if they are not updated.
Below there is an indication of the temperature measured
(measurement every 10 seconds);
Beside, an icon indicates the function of thermoregulation
currently active: in this case the image of a clock indicating
the automatic mode.
Corrispondence between icons and operation modes:
Automatic
Temperature control environment
according to the weekly program
set by the user.
Program seen as a graph of the
current day.
Manual
Temperature control environment
in accordance with a user-selected
temperature (thermostat function).
Summer
Temperature control environment
disable.
Summer ventilation can be
activated manually.
Standby Temperature control environment
disable.
In “automatic mode”, the cronothermostat performs the
temperature control program was set for the current day,
the graph is visible at the bottom of the display.
The graph is divided into time intervals of 15 minutes,
corresponding to a pixel horizontally, and in the four
programmable temperature levels.
Near the icon of the operation mode other icons may
appear. If the hot air generators is turned on appears flame
symbol, different sizes depending on the modulation level
of the flame ( ). If it present a lockout or a fault
appear symbols ( , ) respectively and if it is not
present the connection icon appears symbol ( ). No icon
appears in the visualization if the hot air generators is in
stand-by and has no problem.
Under the indication of the room temperature may be
present, in addition, a line of text that provides information
to the user in special cases, such as the presence of error
or the status of additional functions
Here there are the messages that may appear, alongside
with their meanings:
Starting… Kronos is in the process of connection to the hot
Room temperature sensor on Kronos damaged.
Fault code xxx There is an anomaly or a lockout on the hot air
Comm. error Communication error between Kronos and hot air
generators.
Error ID xx The Kronos fails to correctly interpret of
information sent from the hot air generators.
Note: Please refer to the thermoregulation board's documentation for
detailed description of the fault codes and error codes.
The buttons on the right, marked with + and -, allow to vary
the temperatures required for the automatic program (T0,
T1, T2, T3). Instead, in “manual mode” (icon ) allow to
vary the set point room temperature.
Pushing the buttons on the left, marked with arrows, you
can browse the pages of first level menu.
Pushing the button ▼, the following display appears.
Pushing the buttons +/- you can vary the temperature and
pushing the button OK you activate the “manual mode”.
Pushing again button ▼, you can activate the "summer
mode", which is not active environment thermoregulation.
The management of the cronothermostat by the user is
much simplified. The functions are not distinct between the
functions relating to hot air generators and functions
relating to thermoregulation.
If you select the "summer mode", you can turn summer
ventilation through the function key [Vent.]. Once activated
ventilation, a key mark becomes [V.OFF], and it is possible
to stop the fan using the same key.
