3.11.5 Send heartbeat and receive timeout
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 commu-
nication objects requested must be transmitted at least once.
Fixed times are specified as follows:
– Receive timeout: 31 minutes
– Send heartbeat: 15 minutes
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.
3.11.6 Startup
The application is restarted after every reset, so that all the connected motorized
valve actuators are synchronized (see "Control outputs", 3.7).
After a reset, it takes up to 5 minutes for all the connected room thermostats to
restart. This is designed to avoid overloading the mains power supply when
restarting. At the same time, it reduces the load on the KNX network, as not all
thermostats transmit data at the same time. The delay (T
WaitDevice
) is determined by
the thermostat's device address. After the delay, the device starts to send.
3.11.7 Heating and cooling demand
In conjunction with Synco, the heating and/or cooling demand from each room is
transmitted to the BACS to provide the required heating or cooling energy.
An example for LTE mode is described in section 3.11.4.
In S-mode, the current state signals of the control outputs are available.
