Push-button, 4-gang plus with room temperature control unit and IR receiver
Multifunction with RTCU and FanCoil 1817/1.0
Activating the time control
Use push-button as master clock
Set a push-button as the master clock in order to syn-
chronise the time for other push-button (slave clocks).
Make the following settings:
1
"General" tab for the master clock: Set the param-
eter "Send time cyclically" to the value "Every
minute", "Every hour" or "Daily".
2
"General" tab for the master clock: Select the for-
mat for the time that is sent.
3
"General" tab for the slave clocks: Set the parame-
ter "Send time cyclically" to the value "No".
4
Connect the "Date/time object output" objects to
each other, or the "Time object output" objects, as
the case may be.
5
Set the time on the master clock.
The time is synchronised on all the other push-buttons.
|
This only applies to transmitting the time. The date
is not transmitted to the bus and cannot be set with
the menu buttons.
Parameters for the switching times
Time control is deactivated by default. Furthermore, it is
initially not possible to specify the switching times via
the control menu ( -:- is displayed)..
If you want to use time control, you have to over-
write the switching times once with an ETS down-
load.
The following switching times are set by default:
• Switching time 1 = 06:00
• Switching time 2 = 12:00
• Switching time 3 = 18:00
• Switching time 4 = 22:00
|
The switching times are not carried out until the
time has been set once via the control menu or via
the time object.
When a change is made from a "holiday" to a "working
day" or vice-versa:
The push-button carries out the last switch times that
are programmed up to the current time, taking into ac-
count the new state.
