10.1 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 communication objects of a device must be received at least once. If a
communication object is not received within this period, a predefined value is used and
an error message generated. This ensures that interruptions in communication are
identified at an early stage.
Similarly, send
heartbeat defines the period of time within which all requested
communication objects must be transmitted at least once.
The time intervals are based on the size of the network. Normally the basic setting can
be retained. In the case of S-mode communication objects, shorter times may be
selected for smaller networks or for test purposes. The receive timeout must always be
longer than the send heartbeat.
Parameter Basic setting Range Resolution
Receive timeout 60 min 0 ... 105 min 5 min
Send heartbeat 45 min 0 ... 105 min 5 min
(0 = not enabled)
Fixed times are specified as follows:
Receive timeout: 31 min
Send heartbeat: 15 min

Parameter Short name Basic setting
*128 Receive timeout 60 min
*127 Send heartbeat 45 min
10.2 Digital inputs
The following potential-free contacts can be connected to digital inputs D1 and D2:
Presence detector or window contact (see section 5).
Dewpoint sensor (see section 8.2.5).

Do not connect the same type of sensor / functions to both digital inputs.
The controller would ignore the second input.
