I have a considerable investment in Lenz hardware, as it was my first system. So
I have been trying to migrate this equipment to Commander.
For a while I have been trying to find out if a Lenz LB101 (current sensor) could be used with a
Viessmann 5217 or similar S88 device. I got some negative responses. So I
shelved the idea for a while. I just decided to revive the idea. This is what I found.
I was able to migrate the LS150 (turnout controllers) and they worked perfectly. But the LB101/LR101
occupancy combination was a problem.
I gave up on the LR101 (occupancy Decoder) because Jurgen Meier informed me, in an earlier post, that it was incompatible, due to the Lenz proprietary RS bus. So I decided to focus on the LB101.
Some research found that the LB101's output is nothing but a transistor switch. It's the transistor section of a opto isolator. Nothing proprietary here.
Well just as I thought, the LB101 works perfectly with a Viessmann 5217. With
the added benefit of 16 current monitored occupancy zones instead of 8 as in the Viessmann
5233 and others.
Now this probably would not be cost effective to buy 8 LB101's and a 5217. When
a ready made Viessmann 5233 is available. But it sure fits, for someone like me.
Since I am now able to re-use existing equipment.
I hope this helps someone out there.
