PRO time programs
Dependent on the corresponding system configuration, the com-
ponents of the system can be controlled individually. By pressing
one of the yellow keys of the user keypad, the controller is
switched to the corresponding continuous operating mode (refer
to the section on operating mode selection). The controller nor-
mally operates in
mode. By suitably programming the time
programs PRO 0...2, several components of the system can be
triggered once (timer) or repeatedly (weekly and annual pro-
grams). The operating status of the system can be influenced
by several sources in the following manner:
Possible conflicts between the individual sources are solved by
different priorities assigned to the sources (Example: annual
program specifies: heating circuit 1 ON, weekly program spe-
cifies: circuit 1 OFF; the annual program has higher priority than
the weekly program, therefore heating circuit 1 is switched ON).
The timer has the highest priority; it can therefore not be inter-
rupted by the continuous operating mode (disabling is, however,
possible with PRO 0 = 000 (h)).
The controller has 3 time programs:
PRO 0: 1 timer (hourly count-down)
PRO 1: 1 weekly program with a maximum of
40

PRO 2: 1 annual program with a maximum of
