In a KNX network, S-Mode and LTE Mode communication objects can be exchanged between individual devices. The Receive timeout defines the period of time within which all the communication objects requested from a device must have been received at least once. If a communication object is not received within this period, a predefined value is used.
Similarly, the Send heartbeat defines the period of time within which all the communication objects requested must be transmitted at least once.
LTE Mode / S-Mode
Fixed times are specified as follows:
Receive timeout: 31 minutes
Send heartbeat: 15 minutes
| Object [KNX obj. Nr.] | I/O | Minutes | Default value |
|---|---|---|---|
Room operating mode: Time switch [12] |
Receive | 31 | Comfort |
Room operating mode: Preselection [7] |
Receive | 31 | Auto |
| Application mode [31] | Receive | 31 | Auto |
Reducing the bus load
Individual zones can also be disabled (out of service) via control parameter if they are not being used. In disabled zones, the LTE signal will no longer be periodically sent, and will therefore reduce bus load.
