<<100%
Correct ...
however I definitely subscribe to the "If someone rips it's guts out then
it has
to still work" camp and so I would be using these to switch an electric
radiator
valve directly without necessarily using HV to monitor and control
temperature at all ... I'm very conscious of leaving something that the
next
owner can use easily and I don't want to present them with HV and a
programming
manual! I use HV to add functionality to an existing subsystem but the
subsystem
itself must be able to work on its
own.>>
And rightly
so. I
was proposing that Mark could use the sensors and HV to provide
ADDITIONAL
control - retain the existing setup so that it still works - just perhaps
turn
the thermostats down to 10C as a failsafe. That way, if HV packs up,
(a)
the house wouldn't freeze and (b) you could manually whizz the 'stats up to
<insert your chosen temp> and everything would be
A-OK.
The electric valve
idea
is sound - as long as you remember that if ALL valves are OFF that your
boiler/pump can cope - bypass loop or a radiator controlled by lockshield
valves
which DS hasn't shut down ;)
