"Excellent product. Gives so much more flexibility then my old Tempus 3. Easy to fit as the wiring on the new back plate was a one for one swap with the old one - other than the earth terminal, which was much easier to wire in on the new plate as it has been fitted in a different position. Somewhat expensive compared to the standard range of programmers. Very simple to setup as the weekday/weekend pre-sets suited me fine. The text display is easy to read and there are no more daylight saving adjustments either! I would suggest leaving the backlight setting at timed, rather than on all the time - looks like daylight in the kitchen when going in after dark with the lights off...!"
