I have searched the forums here and found the wireless timer/thermostat I have, the Vaillant vrt340f (typo corrected), described as 'diabolical'. I could not agree more. I build and program computers and I have never come across a device so infuriatingly hard to use.
My heating comes on in the middle of the night. When the weather is boiling the rads are on, when it's freezing they are off. The only function that is easy to understand and program is the holiday setting. The rest of it is a nightmare.
I want to replace it. It is controlling a Vaillant 837e combi. Apparently I can take out the rf receiver unit from the boiler and replace it with a clunky 24 hr mechanical timer from Vaillant. Nothing in between.
I just had a very good plumber here who did a great job replacing a Saniflo but when I showed him the boiler problem he just scratched his head. His trip to his supplier came up with the advice about the mechanical timer, and that's it.
Before I installed the Vaillant combi I used to have a Drayton 7 day 24/7 timer, that was simple to operate and use, practically foolproof. There must be some way I can use something similar with this Vaillant!
All help and suggestions gratefully received.
