The chronothermostat provides the functions of reading
and writing of the TSP, as shown above.
Pushing the
↑
and
↓
buttons, you can move the index "idx"
and pushing SET button the next page appears.
On this page using the + and - buttons, you can enter the
desired value of the TSP.
If the thermoregulation board does not provide the writing
of this TSP (read only) changes will not take effect.
The fourth items in the "PARAMETERS MENU" allows the
consultation of the "Fault History Buffer" (FHB) of the boiler,
i.e. the storage the lock codes which may be useful for
diagnostics.
This function cannot be managed of the thermoregulation
board.
The values are displayed in groups of four per page and
you can scroll through pages with
↑
and
↓
buttons.
The chronothermostat also provides in this case the
maximum number of parameters 255, with idx ranging from
000 to 254.
The last items of the "PARAMETERS MENU", contained in
the second menu page, are typically used for technical
work on the chronothermostat.
In particular, "OT monitor" is dedicated to the diagnosis of
OpenTherm communication, as it makes visible the data
exchanged
between
chronothermostat
and
thermoregulation board (master side).
In particular, next to the data, the following symbols
appear:
‘
●
’
correct data exchange
'T'
timeout RX error
'R'
RX error
'?'
generic error (unknown)
'P'
parity error
'E'
syntax error
Through the "Restart" command is possible to reconfigure
the chronothermostat after interventions hardware /
software occurred without disconnecting the power adapter
on thermoregulation.
Pushing the button "Restart" is equivalent to disconnect
the connector of communication.
The submenu "RS232 Monitor" is shown in the following
section, remote management via GSM-SMS.
REMOTE MANAGEMENT VIA GSM-SMS
Connecting a GSM modem
The
FIAMMA
OT11 chronothermostat allows the user to
remotely manage some functions of the heating system by
sending and receiving SMS messages.
The boiler responds at the set number in case of anomaly
status and lockout status. In order to use the GSM network
is necessary to connect external GSM modem;
The GSM modem must have its own power supply and
must be connected to
FIAMMA
OT11 with a dedicated cable.
To
install the
GSM modem
, refer
to the instructions
provided by the
manufacturer
of the
modem itself
.
WARNING!
To avoid connecting the signal ground GND of the
serial cable!
Necessary to isolate the casing of the GSM modem, if
this is connected electrically to the signal GND.
