Good room thermostat, it has a differential of 0.2 but not 0.2 up and down. At 0.2 below it turns on and off when it reaches the set temperature. I raised it to 0.3 and maybe I will even go to 0.4 because the burning cycles are quite short and I don't know how much it saves with a pellet burner. As for the accuracy of the temperature, it has it but there is a delay in perceiving it. Overall, a good product.

It is a very good thermostat. I have two others, very accurate in temperature and with a temperature differential setting of 0.2. You have the temperature you want in your space with precision.
