This is the device that I suggested to you the other day, isn't it - to solve your remote TRV issue?
Danfoss (along with Drayton and Honeywell which I mentioned) are reputable brands. I've not used used this device but have 2 Danfoss controller units running my system. They are a well made British brand.
Yes Buildersmate, this is the one.
I want someone who has actually used one, to reply, because it is quite expensive - about �42 delivered.
many thanks.
you may find an answer difficult to come by because the units haven't really taken off and i have heard the honeywell versions have been proving problematic
