Hello, welcome to the forum.
Yes, unfortunately W100 does not allow you to use it as a thermostat in conjunction with the T2 relay. This function is supported only in W500, W600 and TVR E1. At the moment I have started a course of lessons dedicated to the heating system. The first lesson is creating a smart schedule based on automation. The following lessons will be dedicated to your question. Automation 2.0, lesson 10, room climate control. Creating a smart heating schedule for radiator thermostats (E1, W500, W600)
