V3 - GRMS Room Compact Modbus - MC-230-01 is a compact GRMS room variant based on the MC-230-01 controller.
This variant is intended for simplified room configurations where integrated RS485 communication and direct IEX connection are required. Because MC-230-01 includes RS485 and IEX-2 terminals, separate CAD-BC and CAD-232 modules are not required for this room concept.
This variant is suitable for rooms requiring:
| Group | Component code | Description |
|---|---|---|
| Room controller | MC-230-01 | Main room controller with integrated Ethernet, RS485 and IEX-2 terminals. |
| 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. |
| 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. |
| Window contact | MOS-03-HD-WH / MOS-04-VS-WH / MOS-04-VS-BK | Wired magnetic opening sensor for window status and HVAC interlock, if wired version is used. |
| 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. |
| 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. |
| Room sensing | ES-W2 room temperature sensor, PIR sensor and window status. |
| Energy saving | Presence detection, managed power supply and HVAC interlock logic. |
| Central system | Ethernet connection to Linker and S-RMS. |
Compared to MC-24-H1 based variants, V3 uses MC-230-01 with integrated RS485 and direct IEX-2 terminals.
This reduces the need for separate CAD communication modules.
