Looking to upgrade with s type control pack to control hot water and rads separately and would like to know the difference between the available control packs for vented and un-vented. i understand the difference between vented and unvented system but what is the difference between the components in the control packs.
1 x programmer
2 x 2 port motorised valve
1 x electronic dial room thermostat
1 x wiring centre
1 x cylinder thermostat ( not included in some unvented packs)
why do some unvented packs not have a cylinder thermostat included?
are the motorised valve the same in vented and unvented systems?
