Temperature limitation:
A/C units are limited in temperature for each
operating mode by default. This functionality allows configuring custom
temperature ranges, via parameter, in such way that the setpoint temperature
will remain in that range. In case of receiving from the KNX bus a temperature
command with a value out of the configured limits, the temperature value sent
to the machine will be the corresponding limit value.
Auto OFF:
allows an automatic and temporary switch off of the machine (after
an established delay, if parameterized) if a status change in the communication
object associated to it takes place. Moreover, it has an option called "Flexibility
enabled" that allows, if it is enabled, reactivating the unit although it is in the
auto off.
An example of this functionality could be the use of a window sensor,
associated to the auto switch off, which allows switching off the machine if the
window is opened.
Errors management:
this functionality allows sending messages to the KNX
bus informing about errors. Errors management handles A/C unit error codes
as well as any communication errors that may arise.
Besides informing about the apparition of possible errors it can be also
configured the sending of the error type. In case of internal errors, the numerical
code associated to the error type is shown in Table 1.
Regarding the numerical code associated to the type of external errors, please
look up the manual of the installed air-conditioning system.
