19 Fan – Speed 0...100 % (EIS 6: 1 Byte)
This communication object is only visible if the option “EIB: 0…100 %” has
been selected for the parameter
Type of fan
.
Using this communication object, the active fan speed is sent as a
percentage value via the EIB / KNX. With this value, an EIB / KNX analogue
output can be used for example to set an infinitely adjustable fan drive.
Telegram value:
“0”:
Fan off (0 %)
“85”:
Fan at speed 1 (33 %)
“170”: Fan at speed 2 (67 %)
“255”: Fan at speed 3 (100 %)
21 Heating valve – Output for heating valve (EIS 6: 1 Byte)
22 Cooling valve – Output for cooling valve (EIS 6: 1 Byte)
These communication objects are only visible if the option “EIB valve,
continuous” is selected for the parameter
Type of heating valve
or
Type of
cooling valve
.
Using this communication object, an EIB valve (e.g. on the heater) is cont-
rolled by continuous-action control.
Telegram value:
“0”:
Valve fully closed (0 %)
“...”:
Intermediate
position
“255”: Valve fully open (100 %)
21 Heating valve – Output for heating valve (EIS 1: 1 Bit)
22 Cooling valve – Output for cooling valve (EIS 1: 1 Bit)
These communication objects are only visible if the option “EIB valve,
pulse width modulation” is selected for the parameter
Type of heating valve
or
Type of cooling valve
.
Using this communication object, an EIB valve (e.g. on the heater) is cont-
rolled by pulse width modulation.
Telegram value:
“0”:
Valve closed
“1”:
Valve
open
23 Controller – Control value for PI controller (EIS 5: 2 Byte)
These communication objects are only visible if the option “on” is selected
for the parameter
Sending of control value
.
Using this communication object, the control value of the PI controller is
sent via the EIB / KNX. This information can be used for visualisation and
for fault location.
