What happens to the time band set on the thermostat if the BUS power supply fails
and is reset?
The thermostat has no buffer battery, so the time setting is lost if there is a BUS voltage
failure. The time can be reset manually, or automatically via the BUS (defined via ETS)
from a KNX device (timed thermostat, weather station, Master, Internet Gateway, etc.).
Is it possible to understand whether the potential-free contact input is open or
closed?
If the auxiliary input was enabled during ETS programming, the thermostat display shows
whether the contact is closed
or open
