Re: Motorised radiator valves

["Karam Karam" <kzkaram@xxxxxxxxxxx>]

Jon,

We supply some Sauter actuators with an M30 fitting, but its also
important to work out if the actuator stroke and fit to the existing
valve pin is suited.

See http://www.idratek.com/HWMisc.htm#RVA001
for more details

You'll also need temperature sensors in each of the rooms/zones that
you wish to control heating in if you want to have independent set
point profiles for these rooms/zones. Alternatively you can just
implement some simplistic strategies such as shut down radiator at
certain times.
