5/ 5

Pros: Easy over-ride of temperature., Easy to fit, wiring to wallplate, then body of programmer clips on. Very clear display and easy to program.

Cons: No over-ride of time periods. , There appear to be many special facilities with the explanations aimed more at professionals than amateurs (but of course one need not use them since the basics are fine)

Very pleased. Allows heat setting at 6 different periods per day. All days of the week the same. I choose that for simplicity of programming because we do not have differing daily patterns. Other version allow weekends or individual days to be set.

4/ 5

Pros: Good, tight temperature control. Huge improvement over old one which seemed to have a 2 Deg lag/slop.

Cons: Instructions could be clearer. Having fully fitted it, I realised it was not completely straight on the wall and therefore needed to remove the cover again. The part of the instruction that shows you where to insert the screwdriver to lift the cover

Used to replace an old Honeywell room stat. Easy replacement.

Pros: Easy to Fit , Simple to setup

This was purchased to replace an old HONEYWELL T6360B1028 stat which was inaccurate, on my oil fired heating system. The instructions were clear and concise the product is neat and un obtrusive, the features such as frost free are great.
