Property me about a year ago, a system acquired the now 5 radiator thermostats, door contacts 8, 10 intermediate connector and some flush switch covers. Unfortunately, the system is not developed. There is no back and forth on important actuators and sensors and is attracting new customers in the first place. There is no sensor for the outside temperature, integration of weather stations or cell phone features is not possible and for switching from central heating, gas boiler, etc. there is no actuator. Unless you sawed an adapter plug and tinkering what. Thanks. Super System. Can only strongly advise against it !!!
