Relay8 to Relay12

Hi,

My current setup is Relay8 + Relay8=16, Im planing to upgrade to Relay8+Relay12=20, any advice?,
The system is connected with comfort and there is program from comfort on and off the light in cbus as well.
what would happen if I just swap relay8 to relay12, do I need to change any setting? please advise me

 

If you install a new relay it will have to be programmed.
Assigning group addresses to the relevant output relay channel is the main thing you need to do.
Use CBus Toolkit software to do this.
Before you make any changes and before you remove the old relay, create and safely store where you can find it again a backup of the project.
Check "all" the settings of the old unit and write them down.

One burden and at least one (recommended 3 for redundancy) active system clocks are required for CBus network to operate.
Make sure you have a plug in burden laying around in case you need it.
Check for active CBus software burden or active system clock on the old unit.

If the old relay is set to unit address 1 there is a good chance it has its software burden activated.
If it is not unit address 1 it won't.
Hopefully the old relay you are removing is not unit address 1 and you can just assign any unused unit address to the new relay.
Come back for more info if the relay you are removing is unit address 1 because removing it from the network will probably kill your ability to connect to the network.

Change any other settings on the new relay according to what you wrote down.
