====== V2 - GRMS Room Direct HVAC - MC-24-H1 ====== ===== General description ===== **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. ===== Typical use ===== This variant is suitable for rooms where: * a reduced number of lighting circuits is required * HVAC can be controlled directly through controller outputs * a separate FC-1-IQ fan-coil module is not required * the room still requires standard access, panel, sensors and energy-saving functions * Ethernet / Linker connection to S-RMS is required ===== Main components ===== ^ 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. | ===== 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 | 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. | ===== Variant difference ===== 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. ===== Notes ===== * V2 is intended for simplified rooms with direct HVAC control. * 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. * It is suitable only when the HVAC equipment can be controlled through discrete signals. * Final output assignment must be checked against the actual HVAC device.
