The key question is what is the dead band? Any controller that can keep the temperature within a 2C range would be fine. I'd try & track down more information, but if your main need is heating in the cool season and it's dead band is around 2C, it would work fine.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
