first of all, thanks for all the replies by everyone - i guess the

property?

Ask away. you will probably get all the answers you need if you ignore
the occasional diversion!

i'm just asking for answers to my concerns - and i appreciate even the
ones telling me i shouldnt be doing some of these things myself - as i
do kind of agree and i apologies if i am misunderstaning/getting
confused on certain stuff.

Don't worry... You will soon find which jobs you feel comfortable taking
on yourself. You just need to learn when to ignore the "wet wing" of the
uk.d-i-y party ;-)

but if you can imagine if you have never seen something before and
wanted to learn, i would imagine starting with the most fundamental
question is an ok way to start to learn? if i was helping someone with
something in my profession, i wouldnt start off by telling them that
they are a troll (whatever that means ...)

From time to time you may see posts asking deliberately obtuse
questions with the only purpose being to start an argument or wind folks
up. Some folks don't remember what it was like to be a novice and band
the term around a bit too easily!

anyways, rant over and here's more questions:

1) i do have a chunky manual room stat - and i cant even find it on the
sunvic website anymore. and i do hear it click as i rotate it around.

Good - the mechanics sound like they are working.

2) i took the motor of the motorised valve off the other night - and
saw a tap spindle. didnt have any lable/indication to say which way to
tur nfor CH or HW etc - so i just turned it the "other" way around -
and my radiators came on!!
my boiler's timer settings was on CH and HW BOTH.

so if i turn the spidnle manualy, the CH comes on.

that means it can only be:

a) the motor is buggered for the motorised valve

if so you can buy the motor part separately from the wet bit. That saves
having to mess about with plumbing if it is just the motor that has gone
titsup.

OR
b) the wiring is not telling the boiler to do CH

correct?

Yup....

or possibly the valve is very stiff and the motor is trying to turn it
but can't. (you would know that from how hard it was to turn manually).

so if i left the spindle in the position where the CH started to work,
does that mean my HW will now NOT work?
i did not see or work out what/where this "mid-position" is though on
the brass bit - is it inside the motor part?

If it is a mid position valve then it would be as the name suggests -
about half way through the rotation between one extreme and the other.
In the mid position you will get the hot water flow from the boiler
divided between the cylinder and the rads. Did you count the number of
wires connected up to the valve electronics?
