holidays or special days via the "Holidays / special days". Entry of holidays /
special days is described in the operating instructions B3144.

With basic types P and C, the holidays / special day program is active only if time
switch 1 is also active. See section 6.9 "Time switch operating modes
, ,
(basic types A, P, C, U)" and "Communication" for settings.

program can be assigned to other controllers. Different sources can be used as the
master. This can be entered on the controller (see section 28.2.4 ""Holidays /
spe
cial days" menu item"). The following settings are possible:
 Autonomous (neither transmits nor receives)
 From the bus: Slave (receives holiday / special day program from the bus)
 To the bus: Master (transmits holidays / special day program via bus)
 The individual settings have the following effect:
