In theory it should be all the control that we need but the b*stard has
a mind of it's own and will insist on trying to warm the bathroom
mid-day and at any other time it fancies when we only want it to come on
for a couple of hours in the morning and in the evening.

That's how it's currently programmed but it seems determined to do it's
own thing. I've been through all the instructions and on to the company
helpline but it seems that because its "intelligent", we just have to
put up with it. This would be okay perhaps if we were using it for
total room heating but we're not, we just want to take the chill off the
floor.

Anyhow, I just want to add a simple 7 day timer into the circuit and
wonder what the least obtrusive, easiest fitted timer might be. On that
can give me two on & offs per day with different times at the weekend.
In fact, I don't really need 7 days, just a weekday/weekend option with
my two on/offs.

Any suggestions?

Is it powered from a dedicated circuit? If so a timer could be fitted in
the CU if there is space. Failing that a DIN rail timer in a small
enclosure will do what you want. An immersion timer may also be suitable.
