Push-button, 4-gang plus with room temperature control unit and IR receiver
Multifunction with RTCU and FanCoil 1817/1.0
Sending edge commands - 1 bit, 2 bit (priority), 4 bit, 1 byte
Examples of use for the edge function
The following activation sequence chart shows the
phases into which the pulse edge function is divided:
Staircase lighting function with cleaning light
function
With a brief press of a push-button, the switch actuator
switches on the light. A long press of the push-button
extends the staircase lighting function (= cleaning light
function) until a second long press of the button switch-
es off the actuator. The switch actuator requires a stair-
case lighting function and a disable function for this
function.
Short and long staircase timer
You can use this function to produce a brief and a long
staircase lighting time with the push-button. The switch
actuator requires no staircase lighting function for this
request.
With a brief press of the push-button, the switch actua-
tor switches on the light, and after a parameterised cy-
cle time (e.g. 3 minutes), it switches it back off again.
With a long press of the push-button, the same function
is carried out, but with a longer cycle time (e.g. 6 min-
utes).
Number of objects = 2 (object A/B)
Object A/B = 1 bit
Object A: Action on release before the long operating time has
elapsed = Sends 1
Object B: Action on achieving the long operating time = Toggles
Connect object A with the switch object and object B with the disable
object of the switch actuator.
