Have the product for about 3 months in use for heating conservatory. I am short - just fully satisfied !!! WHY? 1. The temperature setting is very easy even for a layman. 2. The device works so far performed flawlessly. 3. Once set values are retained even after disconnection (power failure etc.) !!! get 4. possibility (not used by me) - control of a refrigeration unit. Conclusion: Buy recommendation without "if" and "but" - Super product !!! (I have never been a product as "effusive" recommended.)
