With communication activated, the actions are the following:
• Fault status messages are always delivered via bus and can be further handled by
other Synco devices
• Fault status messages from other Synco™ 700 devices are shown on the display
under:
Main menu > Faults > Fault status message bus
• Fault status messages from other Synco devices can be delivered to a fault relay
(refer to section
13.10 ”Fault relay")
All fault status messages can be acknowledged from a remote location (e.g. from the
operator station via OCI700.1; the RMH760B is unable to acknowledge or reset fault
status messages of other Synco™ devices from a remote location).
It can be selected whether fault status messages with self-holding may also be reset
from a remote location or whether self-holding must always be reset with the local
push-button.
14.2 Calendar data (holidays and special days)
Each RMH760B has 4 calendars for holidays and special days. If required, it is also
possible to use a calendar of plants (heating circuit, DHW heating, ventilation, etc.) on
other controllers.
Or, optionally, the plants in the controller can use one of the 4 internal calendars. This
is also effected via the communication settings.

If a common holiday or special day program shall be used, holidays/special day opera-
tion is to be defined on one of the controllers as the master and the other(s) as the
slave(s). This works analogously with the 4 internal calendars.
