In the event of changes in the objects marked with *, the objects are reset with higher priority in order
to get a reaction of the system, except for conditions 1) -3) that always have priority.
Control examples:
With the following operating order:
HVAC-Automatic -> HVAC-Night-mode -> HVAC-Operation-mode-1
initially HVAC operation mode 1 is active, after reset (or timeout) the HVAC night operation is active
again.
In this order
HVAC-Automatic -> HVAC-Operation-mode-1 -> HVAC-Night-mode
The night operation deletes operating type1, after resetting the night operation, the control goes into
the HVAC automatic operation.
Master-slave-operation:
A control unit that works in master operation mode can control several devices in slave operation
mode.The direction and level information is placed via the object-26 IO-Master/slave. If the fan A runs
in the master device in air-supply mode, A also runs in the slave device in the air-supply. If only one fan
is connected, one device must be operated on connection A and one at the connection B.It is always to
be ensured the balance between supply air and exhaust air devices (same number A and B slots),
otherwise the required air exchange and the desired heat recovery will not be reached.
Filter cleaning alert:
Depending on the speed of the fan, cleaning or changing the fan filter is regularly necessary. After
