BOSS Therm BUT2 / BOSS TPSRF31 Wireless Thermostat

[RayPooley]

See the title. That's the combination.

Tried everything to get this brand new installation to work to a schedule. It just seems to come on when it feels like it. 3 o'clock in the morning even.

Installed 6 months ago by a subcontractor of a building company as part of a larger refurb project.

So you know the story. Builder unable to contact plumber who appears to have gone bye bye.

It is straight forward enough when you look at the docs and the timer and tstat are accepting and remembering what you program into them.

Just not sticking to it.

New batteries in the tstat because I know they can be problematic.

Tried switching off the wifi receiver so just the timer is in control. Still doesn't work.

Is there anything peculiar about this kit? Is it crap? Does it have a bum reputation?

Should we get rid of it?

Any advise appreciated

Cheers

There cheap and I find the range isn’t that good and sometimes they do funny things eg wireless room stat isn’t calling but boiler fires due to demand from receiver

So ... get rid or is there a fix? What could cause the receiver to demand heat from the boiler in the middle of the night at 3.00 am? Is that a fault that can be fixed?

Replace

combi boiler or cylinder?

Not combi. Oil boiler and cylinder.

I have just read in the wireless docs that the receiver can be affected by neighbouring units. Now that's possibility. Change the RF address in the receiver. Any thoughts?

Don't like the look of that aluminium tape on boiler flue what's that hiding?

 

[ShaunCorbs]

You can try changing the channel / rf

The boiler and flue is original equipment. So that was there before the plumber did the upgrade. No idea to be honest. My guess would be sealing the flue where it joins the boiler. Whether that means the joint is dodgy or not I don't know but I would hope the plumber might have investigated that on the job. He left it alone so I would suggest it's not an issue.

Yep. Just reading how to do that. It's on the list.

Not a frost stat causing it to come on by any chance?

Looks like you're local to me, Leighton Watkinson is knock around here.

I don't think anyone has tried frost mode but I will check it out.

Just a quick update for those who may have the same issue. I changed the RF address and that sorted it out. The tstat and the receiver were both set to the factory default so whoever fitted them didn't bother changing it. I can only assume whoever installed next door's took the same approach. So that's your solution should you find yourself in this situation. Well, it's the first thing to try anyway.
