Rated 5 out of 5 by Bmweeny1 from Watch out for the bug Bought this a couple of weeks ago and initially looked OK, but then noticed that the heating was coming on outside the program times..??? So reset the device - and re-programmed - no change. It turns out there's a bug with Friday Period 1 As soon as I set the Friday P1 temperature, the thermostat defaulted to the standard program and over-rode the custom timer. I then thought of a work around - shorten the faulty period.!! (set Friday Period 1 to 00:00/00:01 and 14 deg, then set period 2 to what period 1 should be.) ...and it all works now.. Yes, I should really take it back, - I might get a better unit, but it might be worse...?

Rated 2 out of 5 by BCM454 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 caldy 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 cnwcnw 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.

Retro Fit

I am planning on retro fitting this to existing floor heating with out temp sensor, can this be used on room temp only with out fitting the floor sensor supplied

Asked by: Frodo111

It is possible , But we would recommend for the floor sensor to be replaced and to be used instead of the air sensor.
