Unsutable connectons aganst the manual mght cause health, lfe or materal
damage rsk.
- Do not power on the devce before all the connectons are completed.
- Check the devce user manual to create a secure connecton.
- Do not make any connectons other than the connectons specfied n the scheme.
- Do not connect wth devces that do not comply wth securty standards.
Mount the devce away from metal surfaces or objects to avod any negatve

The devces use nohom communcaton protocol. 2 Channel Relay Module can
wrelessly communcate wth other nohom products and can learn and swtch
output state values of other products.
İnohom IP Gateway devces (Nova Panel/Home Manager) enable managng other
devces ntegrated to the automaton va the nternet by enablng the system to

The commssonng of the nohom products after assembly s completed by the
authorzed nohom dealers and techncal staff. Detaled management panel
nterface ensured communcaton and other settngs between the devces.
At commssonng stage, the “FIND” button on the automaton control panel nterface s
used to dentfy the related devce.
The LEDs on the devce wll blnk wth 1 second nterval when pressed “FIND” button
and press “STOP” button when the devce s found.
Then, settng parameters are sent to the related devce wth “MATCH” button and the
devce becomes operatonal.
“IO TEST” buttons on the control panel nterface can be used for testng the correct
cable connecton of the devce. The state of the desred output can be changed as
on/off and energy flow towards the termnal s dentfied.
