Who wants to have it very noble, can integrate the device instead of the supplied cover frame in a control panel; in the manual several most suitable switch series are given. It looks really professional standard.
Knowledge one should remember that the device is intended primarily as a central control for multiple HM-CC-RT-DN wireless radiator thermostats. A direct control of actuators (HM-CC-VD) is not provided, since the wall thermostat not manipulated variable "valve position" outputs. Nevertheless, you also get the latter combo up and running, if you linked the wall thermostat in FHEM with a virtual channel, which then actuates the valve and all via a software controller at the head office ("PID20") governs.
