**SystemeComf Modular System From System Electric For Comfort Control Presented**

The Russian company Systeme Electric presented the SystemeComf system, which provides comprehensive comfort management in premises.

This innovative solution is easy to use and has a modular architecture, including controllers with a color touch screen and gesture support, various expansion modules and air quality sensors. The system is optimized for controlling temperature, ventilation, lighting and light protection (blinds, curtains) in administrative buildings, hotels and shopping centers. The Modbus RTU protocol allows integration of SystemeComf into a building automation system.

The SystemeComf digital system provides the ability to conveniently control all comfort functions using a single device. Thus, on the color touch screen of the RCFC(P) wall controller with a 4.1” diagonal, gesture support and scene call buttons, users independently select the temperature, fan speed, turn on/off lamps and adjust their brightness, open/close curtains and blinds. When the user approaches the controller, the built-in proximity sensor is triggered and the screen backlight turns on. Pre-configured scenarios that are activated by pressing a button or automatically, for example, by a signal from a presence sensor, allow for maximum simplification of comfort control .

The modular architecture of the system allows comfort control to be implemented using only the necessary peripheral devices. Up to 16 lighting groups for each room and up to 4 curtain/blind groups, as well as conventional key or card switches, can be connected to the expansion modules installed in the control cabinet. Four configurable scenes regulate comfort parameters and are switched on/off automatically or manually. When connected to the building automation system via the Modbus protocol, the controllers transmit current operating values ​​for centralized monitoring, control and energy saving.

Lighting groups are controlled using RCFLM4(D4) expansion modules, which receive commands from the comfort control system controller. The front panel of these modules is equipped with feedback switches for manually switching lighting groups on/off, if necessary. RCFDI8 discrete input modules are available for comfortable lighting control using standard key switches.

The RCFCM2 expansion modules allow manipulation of the sun protection devices. They receive the commands "open", "close" and "stop" transmitted by the user via the controller interface. The devices then send the received commands to the curtains or blinds integrated into the SystemeComf comfort control system with an electric drive activated by a "dry contact" signal.

Indoor air quality control is implemented using RCFSRHQT(L) room sensors used in conjunction with comfort controllers. The sensors record temperature, relative humidity, CO2 concentration level, suspended solid particles up to 2.5 µm in size (dust, soot) and volatile organic compounds (aromatic hydrocarbons, aldehydes, alcohols).
