Connecting the Vesta Building Controller

The inputs and outputs of the Vesta Building Controller are under the two covers and are split up in two parts.
On the upper part all the sensors are connected. The lower part is for the relay outputs.

1.2.1 Mains power supply and relay outputs

The picture below shows the output part.
The mains power supply (230 V~, 50 Hz) for the device must be made on the connections 46 to 51. The connec-
tions 1 to 9 are internally connected and can be used for example to connect the minus of the 24 Volt.
The outputs are potential-free and can therefore be used for 230 V~ control voltage or 24 V~/=. For safety
reasons it is not allowed to combine both 230 V and 24 V on the outputs. In that case use external relayboxes.
The group outputs (10–33) are split up in blocks of 4 relays or 2 groups. Each block has its own common. The
commons are used to put a voltage on the relays. This voltage is switched on the up/down outputs. Because
the commons of the different blocks are next to each other it is very easy to connect them together. Optional
the blocking outputs (SP1–SP8) can be used to disable the individual control on relay-PCB's.
The next diagram shows the internal structure of the Vesta Building Controller's outputs, and a typical installa-
tion for 4 groups with 24 V control voltage and optional blocking (dotted line). Everything above the numbers
is internal, and below is external.
Note: Do not forget to bridge the commons if necessary. In the above situation for example terminals
15 and 16 must be bridged.
