Hi Trying to find a wireless control panel / programmable room thermostat that is compatible with our biasi garda he condensing boiler. Looking for something that does not require an electrician to install (part L / part P requirement?) Anyone know where I might find one or if such a product even exists? Thanks, Mike

Any wireless room stat will do the job. Wouldn't worry about part p\l.
Stuart, thanks for advice. Can i just check:
1) Are you saying this is a relativly easy diy wiring job (have done a bit before) 2) House to be sold soon - lack of part L / P paperwork won't cause a problem 3) Any recomendations and am i best going for simple thermostat or more af a fully programmable thingymabob?Cheers

It is, but if you are the slighest bit unsure then get someone else to fit it.
Wouldn't have thought so. Part p doesn't come into it and I don't think that part l will have any bearing on any reports particularly.
Either\or, but I'd go for a fully programmable thermosrtat if it were mine.
I did one for a neighbours Biasi combi not too long ago. Straight forward - the boiler has a pair of chock block style terminals accessible by removal of a few screws to expose the control board. These were initially joined by a loop of wire. To install the stat one just removed the loop of wire and connected the wires from the prog stat. Any battery operated prog stat would do fine. On this boiler it had an internal timer, so we just set this so the boiler was on 24/7 and left the control up to the stat.
except that the _necessity_ to fit the control is a requirement of part L. If you consider that you need the right paperwork then you'll need to shell out. The received wisdom at the memoent is that the required paperwork is a luxury and if/when you come to sell the house getting the paperwork sorted in one go will be cheaper anyway.
Endorsed. Horstmann do a wireless unit, the receiver unit can often be fitted into the boiler itself.
On this boiler it had an
Thanks for replies. John, can i just ask which stat you used as it seems to have been pretty strait forward to install. Regarding what you did with the internal timer, is this standard procedure? i assume this does not result in the boiler actualy being on 24/7 - just available? and that you can use the stat to switch heating off simply by turning temp setting right down? or am i barking up the wrong tree all together.
Just on the off chance that anyone knows, have seen some of the new breed of wireless stats which don't need any wiring at all (receiver plugs strait into boiler) but as yet have not found one available for our boiler model. Anyone found one of these compatible with biasi ?
Thanks again, Mike

They all use pretty much the same wiring and backplate. Basically you just stick a live and neutral into the reciver unit and wire a pair across the common and call in the receiver to terminals 1&3 in the boiler (check your instructions, but I think the Biasi uses terminals
1&3)
Yep.
Kind of. You could turn the temp right down but if you are using a programmable stat then it has a programmer built in, so you can just turn it off as you would with a seperate programmer\stat combo.
These aren't so much a 'new breed' as such, but are generally supplied by the manufacturer for a particular boiler of there's. They're not generally a generic item.
Fraid not, but then I haven't been looking. Best people to ask would be Biasi themselves.
Don't recall what it was ( it was the prog state he had for the previous boiler). However any stat that can close a contact to indicate call for heat would do.
I use one of these:
Depends on the boiler. Some have a master control that let you chose (for example) Heating once, twice or continuous. This one did not and only had the option of timer control. So setting a single "on" period lasting 24 hours was the way to in effect make the timer redundant.
That's right. The boiler will then run whenever the prog stat says it should.
That's right, you could. In reality if you set what temperatures you want at what times of day then, the need to do anything with the stat will mostly go away. (better ones have frost free settings for holidays etc). They usually also have a nudge up and down capability to override the current programmed temp should you wish to make a temporary alteration.
Never looked, but even one that needs a mains supply to the receiver would be very easy to power by picking up the mains feed in the boiler. There is a fair amount of empty space inside Biasi boilers as well, so it ought to be easy to fit.
Ours had a switch on the boiler for HW only or Heating and HW, I used to switch it to HW only in the summer. Not entirely necessary, but I did find there would be times when a cool night would mean the heating coming on in the morning when we didn't really need it.
Its going to depend a bit on the thermal mass of the house, and how low you set the stat overnight. I find with ours set to 16 overnight the heating never kicks in for the bulk of the summer.
