IHC Visual Model # 120B1202

[Viking1277]

I have an IHC Visual Model # 120B1202 at the core of my house electric switching system.  I recently bought the house and this system is so old that I have no way to understand how it is programmed.  It is managed through an RS-232 connection, which I don't have.  

I don't even know the value of this system other than it is currently programmed to turn lights on and off selectively through long or short presses of light switches.  That is the extent of the system's use in my home at the moment. 

I am curious about upgrading it to the latest technology.  My research tells me that all the input and output components, dimmers (which aren't used), power supplies, and everything else are compatible to the latest SpaceLogic system that was launched today.

However, I don't know what that would do, if anything for my house.  Most important for me is gaining knowledge on how my system is set up, what possibilities I have to add useful features, and if there is a way to monitor electricity usage throughout the house, so I know where we are using the most energy.

If anyone knows what an upgrade could do, how much it would cost, how long it would take, and who I need to contact in Tallinn, Estonia, I would appreciate it!  Thanks!

Hello Viking1277!

I checked with our colleague within Estonia and it seems we do not have a direct SE-Sales or technical support within your region. Sorry for that!
In case of questions our contact forward them to an external (non SE) partner.

Hi Viking

Starting February, LK introduces a brand-new interface to replace the discontinued model 120B1202—and it’s a game-changer for your system.

With this upgrade, you can keep all your existing inputs, outputs, and dimmers while transforming your installation into a modern KNX solution. Simply add the new module(Spacelogic IHC interface type LSS100500) and Wiser for KNX (type LSS100100), and you’ll unlock a world of possibilities:

✅ Future-proof your system with KNX modules from Schneider and other leading manufacturers
✅ Enjoy the free Wiser app for easy control and monitoring
✅ Seamlessly integrate with Apple HomeKit for smart home convenience

To configure, you’ll need e-Configure or ETS6 software (both require a license key). If KNX is new to you, don’t worry—expert help is just a call away.

Ready to upgrade?
Contact a certified KNX specialist today and make your installation smarter, more flexible, and future-ready.

Great answer Tommi! 😊

Interesting! Does the Spacelogic IHC device include a KNX IP-router and can be integrated directly into the ETS software or is the Wiser for KNX required?

Thomas,

      Thanks for the contact information.  Unfortunately, prior to posting this thread on SE I had already reached out to the company you linked to and they quoted me for an entire replacement of IHC for newer KNX components at an astounding figure of 20,000 euros.  I informed them that I was not in a rush and would prefer to utilize the SpaceLogic or Wiser for KNX interface (as described by Tommi Jensen below) to avoid replacing all my current inputs, outputs, and other components.  They did not respond.

Tommi,

      Thanks!  This is exactly what I am looking for and the reason why I posted this thread.  I would love to contact a KNX specialist who is familiar with this new interface.  Unfortunately, the company I have been in contact with in Tallinn, Estonia (the one recommended by Thomas Rohde) is either not familiar or not willing to provide any information about this interface.  Can you provide a contact with whom I may coordinate for purchase and installation in Tallinn, Estonia?  As of now, I am currently using an open-source solution and a Raspberry Pi connected to the RS 485 port to control things.  It works fine for now, but not sure what advantages the new interface could provide over my current setup.  I am for sure not going to do what one company here in Tallinn suggested, which was to replace all my equipment at a hefty price of 20,000 euros.
