I've recently installed a drayton wiser thermostat to replace an old danfoss wireless system, so far so good. I've also got two smart TRVs in the kit, but the supplied locking collar doesn't fit my radiators.
The drayton manual says that their collars are for M30x1.5 valve bodies, but the collar just slips over the threads on my radiators, which are marked "DN15", which I understand means 1/2". Photos of the valve body markings here and here.
Is it possible to get the drayton TRVs to fit these bodies, and if so what bits do I need?
Thanks.
