The orange / grey wires are not connected when using the VR65, only live/neutral/earth (the signals for on/off are sent over eBUS) I installed it originally and I’m 100% sure it used to switch on/off as expected. I did change the original vrt390 thermostat to a vSmart in June ‘19 (just two 24v...

I have a Vaillant ecoTEC 418 / VR65 / vSmart control and just noticed one of the Honeywell zone valves is on when there is no CH demand showing at the boiler (S.31) or scheduled. When DHW is requested via vSmart, the CH zone valve closes and the DHW valve opens and the pump runs. When finished...

SWMBO doesn’t like the draft in that part of the room and likes the look of the ones with fly screen (which will limit the draft too).

Thanks. I can’t find the exact manual with GC number match however can find a very similar GC number manual which has the same max input kw rate as on the rating plate & the fire looks the same. All the manuals I’ve found say the same thing that a dedicated vent is not required so based on what...

Thanks, just found the manual online which says “additional permanent ventilation is not required for this appliance in GB” https://www.manualslib.com/manual/142683/Royal-Cozyfires-Super-Sixteen-Nv-Decorative-Gas-Fireplace.html?page=2#manual I guess that means the air vent is not actually...

A living room has a open flame gas fire with open chimney, there is an air brick in the same room with a missing cover. As the fire has chimney, is it okay to buy a vent cover which comes with a fly screen? - Many say not suitable for gas fires but does that still apply if there is an open chimney?

hard to say if it suddenly stopped or was gradual, the last few months we've noticed when you push the door, previously you could let go and it would close itself, now you have to push it all the way shut (which the kids don't do) or it bounces away and is left ajar. as far as i can see (i've...

The hinge flexes maybe 1mm if the door is twisted but doesn’t feel or look loose at all in any direction. The seal has magnetism and will hold itself up against a metal object when taken off.

I used "Measure" app on my iPhone to check levels left-right and front-back (it measures 0 deg in all directions when placed flat on shelf). Its a built-in appliance stood on a concrete floor so unless something has broken underneath, the legs haven't moved since it was closing correctly. I...

I removed everything from the doors and even removed the shelves and it didn't fix the issue. I read that the vacuum is created by the warmer air that enters after opening, contracting, causing the vacuum effect in these appliances. So, I'm therefore wondering if the inside should be sealed and...

I have the exact same issue as the OP, I’ve been carrying out research which says to check the fridge is level & leaning slightly backwards (front higher than back) and check / re-magnetise the door seals (by rubbing a strong magnet around the seal). In my instance, the fridge is perfectly...

Found and fixed the fault! For anyone reading this in the future, check the jumper between 3&4 on the main PCB X16 location is securely fastened!

ISTR there is a jumper wire when eBUS controls are installed which is linked to RT (so corresponds with the fault), that’s my first guess / place to look... is there anywhere else which wouldn’t show rad demand but everything else works on eBUS?

I swapped the vSmart for my VRT392 and still got the same result, no demand showing for radiators.... I then tapped the front boiler panel a few times and radiator demand started.... so looks like I have “fixed” it but expect it to fail again.. i assume there is a lose joint, possibly on the...

Sorry, typo, s.30 on display (no demand), required temp set to 30 and I checked the zone valve moves / clicks okay.. as it doesn’t use the switch assume that’s okay? As the room stat seems to work (as in it shows the current temp and set temp), I’m thinking it maybe the receiver box at fault!?

Hi, I have a ecoTEC plus 418 boiler with VR65 and VSmart controller. I’ve just switched it from summer mode to winter and found the radiators not heating up. A quick bit of diags shows: - S30 on display - No radiator symbol displayed - d.23=1 on boiler (winter mode) - d.8=0 (no heating demand)...

Have you tried using the copper tails on your new taps?

It's S-Plan with 2xHoneywell 2-port valves. The issue appears to be there is no call for heat (or symbol) at the boiler, which is triggered by the VRT392 thermostat.... (if it were the valve, I would assume there would still be a call for heat at the boiler, just not working.... As it's eBUS...

Yes, OV. I've just moved the valve manually but that didn't make any difference (the valve is connected to the VR65 so not sure that would call for heat if opened manually!) EDIT: I've just looked at my wiring diagram and as I suspected, the value switches are not used/connected when using the...

Hi All, I have a Vaillant VRT392, VR65 and ecoTEC Plus 418 all connected via eBUS. All was working well until today where I found that the DHW works (i.e. it's calling for heat when asked via the VRT392 and is showing the symbol on the 418) however when changing the room temp to heat the...
