Number Text
5302 >1 DHW time switch
For each geographical zone, only one time switch master may be set. If several control-
lers are parameterized as masters, a fault status message will be delivered. The fault is
identified by the time switch master(A) when it receives a time switch signal from some
other master(B) in its own zone. Time switch master "A" will then display and forward a
fault, but no more time switch signal, in order to prevent switching back and forth of the
slaves.

5301 DHW system time switch
failure
The controller always expects a time switch signal from the bus. If not transmitted, the
controller will operate in "Comfort" mode. In that case, fault status message System time
switch failure 1 (or 2 or 3) will be delivered.

Holidays and special days

Each heating circuit and DHW heating use their own holidays / special day program.
Weekdays deviating from the normal 7-day program can be entered by the plant opera-
tor as holidays or special days, using the "Holidays / special days" menu. Entry is
described in Operating Instructions B3133.
The operating mode for the holiday period can be separately selected for each individ-
ual heating circuit and for DHW heating.
Function "Holidays / special days" is active only if room operating mode "Auto" has
been selected. The same applies to DHW heating. Here too, DHW operating mode
"Auto" must be selected.

Communication

If the controller is connected to other controllers via bus, the holidays or special day
program can be made available to other controllers (master), or it can be adopted from
some other controller (slave).
The following combinations are possible:
Entry Effect
Autonomous The holidays / special day program only acts
in its own heating circuit or DHW and only in
the controller.
The holidays / special day program has no
impact on the holidays / special day zone
entered on the "Communication" menu.
