The batteries maintain the data and time settings in the event of a voltage failure on the
KNX BUS (all the other settings are maintained in the non-volatile memory) or if the front
is removed. When the BUS voltage is present, operation is guaranteed even if there are
no batteries installed.
The battery charge status is shown by the number of bars.
When the
symbol appears, this means the batteries
need replacing.
The device is pre-arranged to work in battery mode when it is in one of the following
operating conditions:
- the front is inserted but there is no KNX BUS voltage
- the front has been removed.
In both cases, the device is powered by the battery alone: the
symbol begins
flashing and the intensity of the back-lighting (if active) immediately falls to 60% and
then deactivates after 15 seconds of inactivity.
During battery operation, the heating/air-conditioning control algorithms are deactivated
but you can access the Set, Prog and Easy channel localisation menus, modify the HVAC
mode (in the timed thermostat section), activate/deactivate the hourly profile (in the
hourly timer section). The timed thermostat shows a dotted line instead of the
temperature value.
If the auxiliary output is enabled for controlling a solenoid valve, the relay opens a NO
contact (closes the NC contact) only if the front is inserted; otherwise, the relay remains
in the condition it was in before removing the front.
Completing the customisation
After repeating the above steps to obtain the required hourly profile, you can:
- copy the program onto the next day and confirm the programming by pressing the
and
button keys simultaneously within 30 seconds, or
- confirm the programming without copying it, by pressing the
button key within 30 seconds
and keeping it pressed (you will move on automatically to the programming of the next day).
After completing the weekly programming, press the
button key to return to normal operation.
To activate the program, select the Auto operating mode by pressing the
button key until the
word Auto appears on the screen.
