V2 - GRMS Room Direct HVAC - MC-24-H1 is a simplified GRMS room variant based on the MC-24-H1 controller.
In this configuration, part of the MC-24-H1 relay outputs is used directly for HVAC functions, such as hot valve, cold valve and fan speeds. This reduces the need for a separate fan-coil module in suitable applications.
This variant is suitable for rooms where:
| Group | Component code | Description |
|---|---|---|
| Room controller | MC-24-H1 | Main hotel room controller for room automation, direct HVAC outputs and Ethernet communication. |
| Power supply | HDR-30-24 | 24 VDC power supply for controller and bus devices. |
| Bus interface | CAD-BC | Bus coupler used to connect MC-24-H1 to IEX bus devices. |
| 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. |
| HVAC outputs | MC-24-H1 direct outputs | Direct control of hot valve, cold valve and fan speeds. |
| Lighting | Reduced lighting configuration | Basic lighting, typically limited compared to V1. |
| Blinds | B0 | One motorized blind group where required. |
| 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 | Direct MC-24-H1 outputs for hot valve, cold valve and fan speeds. |
| Lighting | Basic lighting circuits, depending on final configuration. |
| Blinds | One blind group, if required. |
| Energy saving | PIR sensor, window contact, managed power supply and master off function. |
| Central system | Ethernet connection to Linker and S-RMS. |
Compared to V1 - GRMS Room Base - MC-24-H1, this variant uses MC-24-H1 controller outputs directly for HVAC control and does not rely on a separate FC-1-IQ fan-coil module.
