V3.1 - GRMS Room Compact Wireless - MC-230-01 + EnOcean

General description

V3.1 - GRMS Room Compact Wireless - MC-230-01 + EnOcean is a compact GRMS room variant based on the MC-230-01 controller with integrated RS485 communication and EnOcean wireless sensor option.

This variant is intended for rooms where reduced cabling is required, especially for retrofit or renovation projects where window sensor wiring is difficult or not preferred.

Typical use

This variant is suitable for rooms requiring:

compact controller configuration
integrated RS485 / Modbus communication
direct IEX connection
EnOcean wireless sensor integration
reduced cabling for window contact or selected room sensors
simplified retrofit installation
Ethernet / Linker connection to S-RMS

Main components

Group	Component code	Description
Room controller	MC-230-01	Main room controller with integrated Ethernet, RS485, IEX-2 terminals and EnOcean gateway.
Power supply	230 VAC / MC-230-01 supply	Controller supply. Only one supply option is used according to project configuration.
IEX connection	MC-230-01 IEX-2 terminals	Direct IEX device connection without CAD-BC module.
RS485 / Modbus	MC-230-01 RS485	Integrated RS485 communication for Modbus fan-coil, recuperator or compatible HVAC equipment.
EnOcean window sensor	SWO-2-1-00	EnOcean wireless invisible battery-free opening sensor for HVAC interlock without additional cabling to the window.
Corridor access panel	CR-D1-V2-PX-BK	Corridor-side access panel for room access, door status and lock control.
Door lock	EL-B / EL-N	Electric door strike, selected according to door type and installation requirements.
Room touch panel assembly	TGP-4D-01-IQ + TGP-S	In-room 4 inch touch HMI panel with TGP-S adapter/interface board for connecting the ES-W2 room temperature sensor.
Room temperature sensor	ES-W2-WH / ES-W2-BK	Room temperature sensor connected through TGP-S and used for HVAC regulation.
Room PIR sensor	IR-R-IW-WH / IR-R-OW-WH	Presence / motion sensor for occupancy and energy-saving logic.
HVAC outputs	MC-230-01 outputs / RS485	HVAC control through local outputs or RS485 communication, depending on equipment.
Network	Ethernet / Linker	Connection to S-RMS.

Connected room functions

Function	Connected elements
Access control	CR-D1-V2-PX-BK, EL-B / EL-N and door status.
Guest interface	TGP-4D-01-IQ room touch panel with TGP-S adapter and room commands.
Room temperature	ES-W2-WH / ES-W2-BK connected through TGP-S.
HVAC	RS485 / Modbus HVAC device or local HVAC outputs, depending on equipment.
Wireless sensing	SWO-2-1-00 EnOcean wireless opening sensor for HVAC interlock.
Room sensing	ES-W2 room temperature sensor and PIR sensor.
Energy saving	Presence detection, window status, managed power supply and HVAC interlock logic.
Central system	Ethernet connection to Linker and S-RMS.

Variant difference

Compared to V3 - GRMS Room Compact Modbus - MC-230-01, this variant adds SWO-2-1-00 EnOcean wireless opening sensor integration, typically for a wireless window contact.

Notes

V3.1 is recommended for retrofit rooms where wiring to the window is difficult.
TGP-S is part of the room touch panel assembly and is used as the interface board for connecting the ES-W2 room temperature sensor.
EnOcean device compatibility and radio coverage must be checked per project.
Final HVAC and sensor configuration depends on the selected equipment and room layout.
