Re: Real HA - central heating control by the radiator

Hi Kevin,

If you go for a bulk buy, I'd be interested in 6-7 of the proportional

Ian: I think proportional will give you much greater scope for decent
control schemes, although at a cost, obviously. I suspect On/Off is
going to create more boiler cycling.

Cheers,

Dave
