I have a Danfoss TP5, Screwfix I think. Works perfectly over the last year,
and what a blessing it is.

I pondered for 2 years on changing mine, as the old mechanical unit was 5
wires, and the new electronic 3 wires, and I couldnt find out how to wire
it. I got a mate to do it that is knowledgable in these things, and it took
about 5 minutes to change.
