Hi all,
I've been through 3 thermostats in the last year. I've tried a few different ones from screwfix. They are the cheaper ones but surely should last longer than they are.
Could there be a wiring problem causing it?
Is there a way to find out with a multimeter?
Current (broken) stat is Drayton rts1 3 wire (live, neutral, switch).
I have a honeywell st699 programmer which seems to be working okay. It did break about a year back and I got a replacement front panel.
Thanks.
