Our house has a fairly large cellar which is about 60% under the street level. So moisture is always an issue. Electrical floor heating has been installed in two segments. I have installed two Heltun heating thermostats. They have an air temperature sensor, a humidity sensor and a floor temperture sensor. Using these values I compute the dew point in Fibaro Home Center 2. When required, also known as risk of mold, the heating is switched on.
