Renovent HR Medium/Large - Brink Climate Systems

Post by sincze » Sunday 23 July 2017 12:00

Hi.

I just wanted to avoid spending over a few hundred euros on automating my Brinks WTW system with:

I thought it could be done a lot cheaper with Domoticz and Mysensors.
https://forum.mysensors.org/topic/7180/ ... te-systems

Next thing would be to power the whole device from the internal 24v of the WTW. Seems possible as described here.

Using the following cable lay-put. Currently mine is 3 wires only so have to modify it to 6 wire.

For now I solved the problem. Using a max of € 10.
I Posted the code on Github, for details please follow mysensors forum link.

As a result I am now able to write som code in such a way that the WTW will start working harder if somebody takes a shower. :D
(Hot water on for over 2 minutes and or humidity in specific area higher than 65%).

Just for some extra information:
C3 is speed preset 1
C4 is speed preset 2
C5 is speed preset 3
C6 is dirty filter alarm indication.

C3 can be skipped becaurse the unit goes to speed preset 1 by default when C4 or C5 are not connected.
C6 is a +24Vdc too C2 when the filter is dirty. I used a solid state relay to create an isolated signal to connect this output to my PLC.

Hey excellent. mine sais FILL ore something like that on the display.
According to your information above I can monitor that as well???

I have to build a new connector then as currently they used an rj11 (phone) with only 4 wires..

And pictures please. we love pictures. :D

I summarized the information of this topic in a cheat sheet.
Source: https://github.com/IngmarVerheij/RenoventHR/

It can be used to convert the standard RJ11 to a RJ12 solution including filter warning (was not included by the building company in my setup)

Only thing I need to do next is find out (without using buck converter) how to convert the 24v to an acceptable digital in for a raspberry / arduino digital '1'.

Nice work! Following this thread with interest as I also have a Brink WTW unit which I want to hook up to Domoticz. Mine came with the remote control option but I don't have any 433 components in my setup (all zwave). Thanks for sharing, I'll take this up once I get time but might need some help :)

Maybe rflink could do the trick for 433mhz?
This solution is with mysensors. :)
