Send on Change
0... 1.0 °C
Sets the minimum
measured tem-
perature change
with respect to the
setpoint that will
cause the thermostat
to send the current
value over the bus to
a supervisor.

the thermostat (up/down)

Temperature sen-
sor weightings
0... 100
For the thermostat's internal
sensor, the Vimar wired NTC
probe (if present) and the KNX
probes, this determines the
relative importance for calcu-
lating the weighted average
of the measured temperatures
[0]
Cyclic Send Time
0 = Off
Sets the frequency in
minutes with which the ther-
mostat (A/B) must send the
measured temperature value
(or the weighted average of
the probes) over the bus to
a supervisor. Activates cyclic
send of object no. 10 and
11 "Current Temperature" of
thermostat A/B
11 = 30 min.
[0 = Off]
Send on Change
0 = Off
Sets the temperature difference
measured by the thermostat
(A/B) that results in the read val-
ue (or the weighted average of
the probes) being sent over the
bus towards a supervisor. Acti-
vates cyclic send of object no.
10 and 11 "Current Tempera-
ture" of thermostat A/B
1.0 = 1.0 °C
[0 = Off]
Current temperature (A/B)
Note:
If you use the Well Contact Suite supervision system to
update the value displayed by the supervision station of the “A/B
Current Temperature" linked to objects nos. 10 and 11, you
must enable cyclic send or send on change. In the event of a
conjunction of a high number of thermostats, it is not advisable
to enable numerous cyclic sends with timing that is too low to
avoid overloading the BUS communications.
