Parameters saving and power failures
The thermostat saves some parameters in a non-volatile
memory to be able to recover them after being shut off (a
power failure, for example). These parameters are the Day/
Night settings, the automatization of the Day/Night modes, the
state of the Lock mode, the maximum setting of the Lock mode,
the Celsius/Fahrenheit mode, the number of hours on the night
time-switch, the language, Fan mode, the number of minutes
associated to a heating cycle, the number of hours remaining on
the night time-switch and the current Day/Night mode. These
parameters are saved every minute if any changes are made,
except for the Day/Night mode and the remaining time left on
the time-switch. These are saved only if the automatization of
the Day/Night mode had not been activated.
Please note that the automatization of the Day/Night modes
is not automatically reactivated when the thermostat is
turned on. The icon for the automatization of the Day/Night
modes blinks to warn the user that the mode was previ-
ously activated when thermostat was shut off but is no lon-
ger active.
After a power failure, if the automatic mode wasn’t active before
this happens, the existing Day/Night mode is recovered. In this
case, if the thermostat was in Night mode before power failure
occurs, time remaining at the night timer at the moment of the
power failure will elapsed before going back to Day mode. After
a power failure, if the automatic mode was active before power
failure happens, the Day mode is automatically reactivated. The
power failure make the thermostat lost his 24 hours periodicity.
So, in this case, users have to reactivate the automatic mode at
the proper time of the day. The Lock mode is also reactivated if
it was activated before the being shut off. However, the icon will
blink for 5 minutes, during which it is possible to deactivate the
lock mode as it was described in Procedures to deactivate the
Lock mode. If this is not done, the Lock mode will stay activated
and the icon will stop blinking.
