The electronic control of the thermal module will automatically
check which zones are connected to the bus.
The menu items of the zone in the electronic control of the ther-
mal module will be available when one or more zone manage-
ment devices are detected.
The electronic control of the thermal module remembers the
zone number detected when a device is connected.
The zone number detected is not automatically removed when
the corresponding accessory is no longer connected.
The zone number needs to be removed manually.

"Yes" with the ▲ / ▼ keys, press the ● key to confirm and
