symbol blinks.) At this point, release the buttons. You must then press down the
bottom button to activate or deactivate the Fan mode. The Fan pictogram will turn
on or off depending on the case.
When the Fan mode is activated, the stop or minimum heating time (off/on) for
a complete 10 minute cycle is established at 90 seconds (factory setting). You
can adjust it from 90 to 300 seconds. This is done to limit the amount of times
the thermostat will turn on or off. Also, if the thermostat reaches a differential
superior or inferior to the 2 degrees requested, it will shut off immediately. The
deactivation of the Fan mode will cause the thermostat to go back to the heating
cycle previously programmed. Once the adjustment is finished, you can exit the
adjustment mode by not pressing any buttons for 5 seconds.
Ventilation intervals duration
You can adjust the minimum time between the fan startups and shutdowns. This
adjustment is similar to the fan activation procedure. First, you have to enter the
fan adjustment mode, as described in the previous section. Then, you must press
down the bottom button for 3 seconds, until the
icon blinks. A duration in
seconds will appear. You can adjust it from 90 (factory setting) to 300 seconds
by increments of 30 seconds. Once the adjustment is done, you can exit the
adjusment mode by not pressing down any button during 5 seconds.
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 Single programming mode, the state
of the Security mode, the maximum symbol of the Security mode, the Celsius/
Fahrenheit symbol, the Fan mode, the number of minutes associated to a heating
cycle, the number of hours of the night time-switch, 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 Single
programming mode had not been activated.
Please note that the Single programming mode is not automatically reactivated
when the thermostat is turned on. The
icon blinks to warn the user that the
