Klima 825502 Intelligent Control Digital Underfloor Heating Thermostat is rated 3.8 out of 5 by 8.
Rated 2 out of 5 by from Very complex This has lots of features but my plumbing and electrical installer and I found it crazily complex to understand and set up. In an otherwise cold house, you set your comfort temp, say 21 degrees and set it to come on 0500 to 0800 every day. It was actually on much more than those hours because it tries to keep roughly warm even out of the active operation window and will be on until it gets within 5.5 degrees of what your desired temp should be. Sounds ok as a principle but SAY SO IN THE MANUAL.This did not seem to be in the instructions (says my builder - the writing is too small for me). Klima helpline did help but seemed less keen to feed back to heir marketing or product people how unclear the set up and operation is. Anyway, I will try this and now understand why it is still on outside of my chosen operating hours. Builder reckons many other controllers are far simpler than this one. Also there is an energy consumption setting that shows a % value. This means % of time it is on, compared with 24/7. Again, really unhelpful until you know that this is what it means. In my view, lots of features but needlessly complicated and confusing to set up. Proof of the pudding is in the eating - in this case heating! Time will tell.

Rated 4 out of 5 by from Replacement Replaced an older faulty thermostat, similar model but failed after seven years. This model has more features. Only installed yesterday so time will tell. The older version worked well over the years

Rated 4 out of 5 by from Better than the old model Bought this to replace a faulty 7 year old Klima thermostat. Easy to fit with clear instructions. There was a choice of 2 fascias and surrounds. What I like the most is the new user interface (display) - it's much clearer what's happening when, and is easier to programme. The time and temperature presets seem to be fine, so that saves a bit of time when you're setting everything up. Can't comment on the reliability as it's only been installed for 1 week, but so far so good.

Rated 3 out of 5 by from Klima 825502 No problem with price -ease of installation and probably reliability. But setup is a pain-the instructions suggest that the on screen menu means you will "flow" through setup. Its not that easy-I think an instructional video should be put on YouTube.

Rated 4 out of 5 by from Thermostat Looks good fits normal back box. Other thermostats tend to be quite big these days. Lots of features look forward to using it when the floor is dry. One small point, no value for testing sensor.
