These types are OK for just setting a temperature
in a
particular zone or room - once it's reached they switch. What they
don't
allow is the ability to have 15C overnight, 20C in the morning, 18C during
the
day and say 21C in the evening (unless you want to keep pressing buttons at
the
appropriate time). Of course, you'd need some way of controlling the
radiator flow in each room to do that.
<<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.>>
