“Easy to fit, though instructions are awful.
1 Warning - Fit the adaptor to the radiator valve first; do not fit the adaptor to the head then to the radiator valve ! - loose one star
2 links up quickly with the hub - add one star
3 works very well as a thermostat head - add one star
4 programming to come on and off and change its temperature it is a black art
I have not mastered & there are no instructions on how to do it - loose one star
5 sure it is possible to programme just haven't cracked it yet! - add a star in good faith”
