Thanks for the update, great it is solved!

Yes, that is what I am going to try as well. At this moment the heatpump should do the same, it gives an on/off signal when it is cooling and this is wired to the HCE80’s. But in my setup I think it...

Ok, just concluded one thing already. For heating/cooling the Evohome works with 2 signals;
Signal 1. The Evohome heat requests by the 1st BDR91T means: if in heating mode “heat” is requested and if...

Are there any users here who have Evohome connected to a heatpump with the ability to cool as well?

This year (before summer :cool: ) I want to use Evohome to switch on the cool mode of the...

Just got some reaction from the Dutch Honeywell Evohome support.

I asked 2 questions to Honeywell;


Answer from Honeywell:


So, not a very helpful reaction for now. But at least it tells a...

Good one ;-)

I’ll contact Honeywell as well.

My installer advised to keep the on/off control, and he contacted Remeha for this.
Just to be sure I just contacted Remeha myself (by email).

Nice!
Ok, that explains a lot. Curious how you can catch the signal send from Evohome to the BDR91 :)

If indeed the BDR91(T) does something smarter than just switch on/off as "told" bij the Evohome, I would assume that the most important difference is that it tries to keep the heatpump "on" for a...

Ok, thnx. If the physical connection is the same (so one on/off connection) I do not yet understand why a new relais is needed to support a heatpump.

I would like to get this version somewhere, (heatpump owner).

The product codes are indeed confusing. However I currently have the BDR91A1000, previously controlled the central heating boiler and...

Hi all,

Just enrolled here. Living in the Netherlands and thanks to this forum I got aware of the possibility to get a beta firmware installed with improved Heatpump control.

Since two weeks I...

There is no outside temperature reported/shown. Should be shown in the top left part on your second photo, directly at the right from the connected two circles symbol and above “quick actions”
