Morning,
I have a job later this week with the above , Viessmann Vitodens System boiler. It has a 4 pipe setup with internal diverter and at present there is a wireless thermostat/programmer controller in the hallway.
Customer wants a Honeywell Evohome System and I just wondered if I can wire...
We have a Megaflo CL210 Cyclinder along with Evohome hot water kit and have come across a problem. We have had solar installed and a Myenergi Eddi solar diverter for hot water but when the Honeywell was originally installed they removed the bottom thermostat probe and inserted the Evohome...
Is there any advice on using Honeywell Evohome with 2 zone heating. Honeywell support are pretty useless and give conflicting advice. They suggested I ask my installer (but my installer suggested I ask Honeywell). I found a support article on the Honeywell Resideo website by Googling...
Looking for a quick bit of advice since I'm trying to wrap my head around what work I need done.
Right now I have an old conventional boiler that heats my hot water tank. The water tank has manual open/shut valve so that I can only heat the water tank and not the heating. I'm replacing this...
I need a little help if possible as I am trying to check that my current system is running efficiently but not really sure how to check, sorry if this is a long one and I have tried to contact a Honeywell connected specialist but they dont seem interested unless installing a new system and the...

Based in South England, UK.
Hope this is the correct place to ask and that ive added all the required info/images.
I had an old boiler that was setup with my evohome system, 12 zones in my house, with controls on each radiator - all worked well.

One is commented to the electric supple to the gas boiler and the other controls the hot water valve.
I have 8 x HR92's all connected and communicating fine with the Evotouch Controller.
However I...
Hi, having fitted a full evohome system before using opentherm and underfloor, having moved into a new build recently, I've decided to fit it again, despite not being able to use OT.
I have a Valiant ecotec boiler which is quite far away from the cylinder. The set up is a 2 zone plus HW, so 3...
Hi, I have an Evohome system in my 3-bed Victorian semi. My system has 6 zones with 9 rads in total each using a HR92 TRV.
It’s been installed for about 4 years and is amazing until last year when a very annoying fault started occurring.
The main bedroom zone, located at the front of the...

We have an evohome system, that controls both hot water and heating
Heating is linked to two zone valves, and the full 12 allowed zones
Switch heating to off, and hot water to off too
Check smart meter at the end of the day and see 70p+ has been used on Gas (not standing charge, just usage -...
Hello,
I have just installed the Evohome Value Pack A which has 2 x BDR91 relays.
One is commented to the electric supple to the oil boiler and the other controls the hot water valve.
I have 8 x HR92's all connected and communicating fine with the Evotouch Controller.

Hi,
For EvoHome users/installers out there.
Is it normal that when I select from Quick Actions - Heating off, the radiators will still get hot as set on individual Radiators valves (HR-92s).
Every time I select heating off (to switch whole heating system off) I can see that some radiators are...
I have a Honeywell Evohome system that is in general working well but one of the HR92 radiator valves has suddenly stopped working just before Christmas
The valve appears to be communicating with the controller but the valve was stuck open. It appears to be communicating with the controller but...
Hi, we have the evo home heating system. Replaced batteries in TRV. The kitchen radiator is roasting hot always….trv doesn’t seem to be regulating temp.
Unbound and rebound to no avail.
What’s wrong?
I am urgently in need of a new boiler install in Huddersfield. My plan was to go with twin Opentherm boilers around 30KW each System is a very large listed home with currently a failed Potterton Eurocondense EC 65 KW, evoHome and pressurised water cylinder. Fan has died and is discontinued. If...
Hi
I have a normal on/off thermostat connected to my Ideal Vogue Max 40 and have been looking through the installation manual (here) to see how to connect an Opentherm stat.
The instructions say "The link wire on the 230V installer room stat/timer connection gives a demand in conjunction with...
our combi boiler has been controlled by a honeywell cm927 wireless thermostat. it has now packed up, and i was looking at getting the hive or nest, however i have now seen honeywell do the evohome, if i went this option would i need to wire in a new controller at the boiler? or would evohome...
Hi
I would appreciate a reply from someone who has an Evohome system fitted please.
When the system is near its set point (but not over it yet) then the Evohome appears to restrict the HR92 on the radiator down and call for heat from the boiler (default on time of 1 minute in every 10).
Now 1...
Hi
When the zones are near temperature (if far away it keeps boiler fully on instead) it seems that the Evohome is bringing the boiler on for 1 minute in every 10 (as some of the zones are reporting not at 0% even though the system is reporting that it is at temperature).
I believe (though not...
