helpful, thank you

Hello everybody, can I run to Boiler thermostats with one controller?

[@Barrysailing]

Hi Richard, great videos thanks. I would like to use my EVOHome controller to act as a room thermostat for the room it is locate in, but can't find how to do this. Can you advise please? Yes it is in the same room which has two radiators, both with HR92s

[@MWPHS]

Is the room it’s located in controlled by a HR91 or HR92 radiator controller?

[@barrydyer4560]

Yes it is in the same room which has two radiators, both with HR92s

[@MWPHS]

@@barrydyer4560 when you setup the zone you choose to use the internal sensor in the evotouch controller rather than the HR92 as the sensor. Contact Resideo/Honeywell Home on 03001301299 if you need support.

Hello Richard, thank you for the great video. I have a question: if i have for the same room more than one heating radiant panel, what can i do? E.G. I have a big leaving room with 3 radiant panel. how to make this as one zone? thank you for your feedback. BRs, Bartolomeo

[@MWPHS]

When you bind the BDR91 you can bind 3x BDR91 at the same time by putting them all into bind mode at the same time.

Hello! I have 1 evohome controller and 5 hr92 radiator valves. Can i place the evohome controller in a room with no radiator valves and use the internal sensor to start the boiler for that room and the rest will strat the boiler from the radiator valve? Or i need 6 radiator valves? Thank you

[@MWPHS]

Unfortunately the system doesn’t work like that. If you are smart zoning, you need them on each radiator as they control the flow of ‘energy’ to each radiator if that makes sense?

[@marekc8654]

Hi. Are they any other relay units that evo home can conect to.

[@MWPHS]

No, just the BDR91 or the R8810A OpenTherm Bridge.

[@waynemountford9656]

Hi can you have 2x HR91 in one room?

[@MWPHS]

Yes you can. 👍🏻

[@EvgenyVizelman]

I have an Immergas hydronic boiler, currently on a Siemens thermostat. I also have a Panasonic ducted air conditioner, on a Panasonic controller (two core cable). Is there some way I could have both these units controlled through the evohome? I'd like them to be smart and wifi controllable, but also don't want to have two separate controllers. Thanks!

[@MWPHS]

Potentially you could create an ‘electric heating zone’ comprising of a thermostat and relay box within an evohome system and this will run independently. Only problem you would have is evohome is a heating controller and cannot do cooling in the manner I suggest (logic would be reversed).

[@drhamerahussain]

cs92a two of the rooms have egg timers . how do i set the temp via the t87 also please ?

[@MWPHS]

Have you changed the batteries in the CS92A?

[@drhamerahussain]

@ yes battery changed . It’s just one of the rooms now

[@EtienneL-it2gp]

Nice video ! Do you know if the Evohome and HM80 can control the main mixing valve of my installation (not only for a zone) ?

[@MWPHS]

Hi, evohome and a HM80 (if you can find one) controls mixing at zone level only.

[@EtienneL-it2gp]

@@MWPHS Ok. That means it is impossible to configure the Evohome to control the 3 way mixing valve depending on the whole house demand ?

[@MWPHS]

@@EtienneL-it2gp why would you have a mixing valve controlling the whole house? A mixed circuit is usually part of more than one zone where the temperature to the one circuit is higher than the second circuit (1x radiator circuit and 1x UFH for example).

[@EtienneL-it2gp]

@@MWPHS The main 3-way valve makes it possible to precisely adjust the water temperature of the whole circuit according to the needs of the radiators. My installation was designed like this.

[@MWPHS]

@@EtienneL-it2gp ok, well evohome is not designed to work like this unfortunately.

[@Uk2pakistanonbus2024]

Sorry, I forgot to mention I got two valiant boilers need to run together example one Boiler Upstairs and one Boiler for downstairs

[@MWPHS]

Unfortunately, you cannot run two boilers with one evohome Controller.

[@MaikelvandenWildenberg]

Good video! Can you make a video using 2 BDR91T? One for cooling and one for heating? I have a Daikin Altherma 3. I think that I need to use 2 pieces for this, but I don't know for sure yet.

[@MWPHS]

Yes no problem I will work on this next week. Just to note that the two relay configuration for heat pumps is just specifically for ‘heating/cooling changeover’ and the heat pump must have this functionality for it to work.
