The connection modules for wired and wireless thermostats (Schlüter-BEKOTEC-THERM-EAR and Schlüter-BEKOTEC-THERM-EAR-WL) can be connected to the Schlüter-BEKOTEC-THERM-EBC "Control" base module and supplied with energy. A mixed installation of both connection modules is also feasible. The respective modules supply the wired room sensors with 5 V DC safety extra-low voltage (SELV). The connected actuators are supplied with 230 V AC. For special convenience, the LEDs clearly indicate the operating status and voltage supply.
