Implementation and wiring

The Tyness and the board must be disconnected.
The board must be installed carefully and with precision of connectors on
the locations EXT.1 and/or EXT.2 of the Tyness.

In the case of the board fitted with connectors, the wires of the inputs must be inserted carefully into the terminal blocks as shown below.

The clamps are not polarized.

To extract a wire, it is necessary to insert in advance, a fine tool into the opening above the wire as indicated below. This will release the wire.
