it is very good for its price. it has 7 restarts in 24 hours. option for five-day operation (Mon-Fri) and weekend separately.. differential from 0.3 to 0.5 that is if you set point 20c and differential 0.3 then you have start 19.7 and stop 20.3. it also has other useful settings that I am too lazy to write. it is so good that it forced me to evaluate a product for the first time. give it a little time to understand the settings (it has Greek) and you will not be disappointed.
