Room Controller RC/A 4.2 Mounting in False Floors For easy underfloor installation, the RC/A 4.2 fits into the common floor boxes and outlets. STO/G – Slide 4

Room Controller Three New Module Types STO/G – Slide 5

Room Controller SA/M 2. 16. 1 Switch Actuator Mod Room Controller SA/M 2.16.1 Switch Actuator Mod., 2-fold, 16 A, floating contact For switching of big loads up to 16 A (e.g. socket outlets) Switching power is equivalent to Switch Actuator SA/S x.16.1 The device provides floating contacts. The voltage has thus to be applied directly to the module Note: Output terminals are not pluggable. Non-pluggable terminals STO/G – Slide 6

Room Controller SD/M 2.6.2 Switch/Dim Actuator Module, 2-fold, 6 AX Substitudes Switch/Dim Actuator Module SD/M 2.6.1 Higher relay switching capacity (see Switch Actuator Module SA/M 2.6.1) Max. continuous current: 6 A STO/G – Slide 7

Room Controller LR/M 1.6.2 Light Controller Module, 1-fold, 6 AX Substitudes Light Controller Module LR/M 1.6.1 Higher relay switching capacity (see Switch Actuator Module SA/M 2.6.1) Max. continuous current: 6 A Note: Fits only for Light Sensor LF/U 2.1 Light Controller functionality is according to LR/S x.16.1 LF/U 2.1 STO/G – Slide 8
