The second person also said that the On and Off frequency for hot water is different and so it would need to be excellent for both - albeit there is no way to check until it is in position.
Originally posted by uhhu View PostBased on the above, I am not convinced that speaking to Honeywell myself will provide any real benefit.

quick question regarding the heating (I have a combi so know nothing about your hot water side of things).
Was this a totally knew install with a new boiler, if so its likely that the boiler temperature may have been reduced to encourage condensing.. talk to your installer about it.
Also a quite way to check if its the hr92 is to unclip it from the radiator. there is a little slider at the front. Once removed it will have no effect and as long as heat is being called for you can see how hot the radiator gets without the influence of the HR92.
Also if you have an automatic bypass, it may be worth checking its setting,

The first half of this sort of makes sense and sort of doesn't. What do CS92 problems have to do with the BDR91? Unless they're saying they think the CS92 is working fine, but then the link from the controller to the BDR91 is dodgy so you're not getting the right outcome? That's plausible. Remember, everything in Evohome talks via the controller - no other components talk to each other. How far are the CS92 and the BDR91 from the controller? We have a very large house (c. 4,000 sqft) with solid walls and we don't have these sorts of problems.
Nothing to lose by trying!
Again, it's worth a go. Your problems are broadly consistent with those reported by people who have battery connection issues. What have you got to lose?
The BDR91s are around 10m from the controller currently. The controller cannot be moved, as one of the radiators is at the opposite end of the house. The controller is in the sweet spot as it talks to every room that I have a TRV installed. There are rooms that the controller will not get to, which is a separate criticism of the Evohome system, but it's also due to having a bigger than average property, so I am in no position to start complaining.
I will give them a call now that the actuator problem has disappeared and its now only the signal failure.
I don't want to tamper with the CS92 in case it needs to go back, I wouldn't want to do something which would void the warranty on it.

For each HR92 go into the settings menu (hold the button down until you see the menu appear) then go to option 6, press the button, change it from 0 to 1, press it again then go to exit and press it one last time. This will change the pin stroke to maximum stroke. Then trigger a re-calibration of the valve by unlatching it, lifting the HR92 off it's base, turn the black wheel fully anti-clockwise, then put the HR92 back on and latch it again to lock it in place. After about a minute you'll see CYCL as it cycles the pin through it's movement range.
If my hunch is right this will allow the radiators to get properly hot.
The radiator definitely feels hot hot, which was helped when I bled the radiators, and the system settings said that 100% was going to the room.
As this was a relatively easy job to do, I will likely do on all the radiators and see what effect this has, even if its 1c, then its a benefit.

This is the bane of my life.
1st time setup I had a couple of issues which resulted in my bringing all controls through a wall and into the kitchen with the two BDR91s the CS92 transceiver spaced out across the top of my kitchen cabinet making sure they are at least 30cm away from each other, and any metal objects.
Everything was okay for a couple of weeks, until this week when the heating BDR91 started flashing red. I was still able to control the heat to all the radiators with an Evohome zone valve (the radiators would call for heat when needed then stop calling for heat), but the green light never goes off when the Evohome radiators stopped calling for heat (for instance, overnight). The green light only goes off if I press the button. This means that all the radiators without an Evohome zone valve are constantly on.
I have done a factory reset on the controller, followed all the instructions on the controller, and still the green light will not go off with all radiators being set to off in the quick action on the controller. I read somewhere that it can take up to 4 minutes, and so I have waited, and waited, but nothing.
At this point I have not set up the hot water to make sure I am not confusing the two BDR91s
Whilst typing this, I have just heard the BDR91 come on, even though the radiators are all set to off, and there is no hot water set up.
Where am I going so so wrong with this?

The only other issue that it could be is a COMMS issue, which from your past experience seems you suffer a lot of.

Originally I had mine set on 3 cycles per hour and 5 minute on time, however I was finding that with this setting the boiler relay was coming on when there was no demand from the system, so it was just circulating round the bypass valve. Not the same issue as yours but could possibly have an impact?

I haven't had a red flashing light since doing the factory reset.
And I keep finding that the relay is turning the heating on even though it is switched off at the controller, three or four times I have had to turn it off manually.
There are no faults in the logbook since I did the factory reset.
When I put all zones to 21c, I can hear the valves opening up. But I am not seeing the BDR91 light up at the same time, albeit, it will come on. However, when I turn them all to OFF, the BDR91 will not go off, but I can hear the valves close.
Hot Water is doing nothing and is not showing any temp. There are no flashing lights, and the position of the relays/sensor has not changed since last it was last working.
And I have received the most unhelpful email:
We would like to notify you that the Total Connect Comfort service restored communication with the heating system installed in the following location:
