# Periphery page The **Periphery** tab is used to configure external RF devices and to control the FCU (Fan Coil Unit). *** ### **Relays Application** The RFTC-3 device allows configuration of five internal relays for various functions: * **Relays 1–3**: Control fan speeds: * **Low** – Low fan speed * **Medium** – Medium fan speed * **High** – High fan speed * **Relay 4**: Heating control * **Relay 5**: Cooling control #### **Flexible Configuration** * The relay settings are highly customizable. Users can configure the relays according to their specific needs. * If 0–10V control is used, no additional configuration is required. ![](https://t10544682.p.clickup-attachments.com/t10544682/badafda6-a94e-4b27-8631-dbb53fdfab60/image.png) *** ### **0–10V Application** The device also supports **0–10V outputs** for smooth control of compatible equipment, such as: * Fan coil units * Valves This provides more precise regulation of temperature and airflow. **Two Output Options** * For **0–10V fan coil** control * For **separate heating and cooling valve actuators** #### **Terminals** Use terminals **9, 10, and 11** to connect devices. Detailed wiring diagrams are provided in the documentation. ![](https://t10544682.p.clickup-attachments.com/t10544682/5d3cf8fc-77ab-4d2b-9d9f-872c227adbf8/image.png) ![](https://t10544682.p.clickup-attachments.com/t10544682/1ff4d2b8-bf2e-4f9b-ab77-9b1b0b12bd9e/image.png) #### **External Input** **NTC Sensor:** If this option is selected, a temperature sensor (NTC type) can be connected to terminals **12 and 13**. This sensor provides precise temperature measurement, which can be used to regulate additional device functions. **NTC Sensor Terminal Connections**: * **Terminal 12**: NTC sensor input * **Terminal 13**: NTC sensor input > For detailed wiring instructions, refer to the diagrams in the manual. ![](https://t10544682.p.clickup-attachments.com/t10544682/b529491d-f8e8-48dd-970b-3d8f7148adc3/image.png) ![](https://t10544682.p.clickup-attachments.com/t10544682/65401b2f-3af3-429b-9427-8fef2dd4bb8c/image.png) *** ### **2x Logical Input** The RFTC-3 device offers the option to connect **two binary (logical) inputs**. These can be assigned various functions such as: * Switch ON * Switch OFF * ON/OFF toggle * Short press * Long press #### **Possible Applications**: These inputs can be used to connect or integrate with various devices and functions, including: * **Door or window contacts** – to detect opening or closing * **Motion detectors** – to detect presence and trigger actions * **Card readers** – for user identification * **Mode Switching Options**: * **Standby** – Energy-saving mode * **Comfort** – Standard comfort mode * **OFF** – Device switched off * **Status Buttons**: * **DND (Do Not Disturb)** – Signals privacy request * **MUR (Make Up Room)** – Signals housekeeping request * **Butler** – Calls hotel service > Wiring diagrams are available in the manual for proper connection. ![](https://t10544682.p.clickup-attachments.com/t10544682/2086dccb-125a-4eb1-bd20-4b3e3284180a/image.png) ![](https://t10544682.p.clickup-attachments.com/t10544682/2c94888e-6eda-440f-8318-7bc5d2d4b048/image.png) ## **RF Inputs and Outputs** The RFTC-3 allows the integration of RF addresses for connected RF devices. These addresses enable linking and control of the following RF components: ### **Supported RF Devices** * **Window and door contacts** * **Motion sensors** * **Indoor and outdoor glass controllers** * **External temperature sensor** * **External relay for controlling FCU or heating (RFSAxx)** Additionally, the RFTC-3 can be linked with **external RF relays** that can replace internal relays for controlling heating and fan outputs. *** ### **Maximum Number of Supported RF Devices** * **RFGS 30B**: Maximum 2 pcs * **RFSW 62**: Maximum 8 pcs * **RFMD**: Maximum 4 pcs * **RFWD**: * **Door contact**: 1 pc * **Window contact**: 3 pcs ![](https://t10544682.p.clickup-attachments.com/t10544682/c04222ad-37a0-4e2b-b404-21052180b3dd/image.png) ![](https://t10544682.p.clickup-attachments.com/t10544682/f571a5db-5eac-4c3a-b245-9fe2d93c3665/image.png) *** ## **Behavior and Interaction of RF Elements** The logic created by linked RF components functions as follows: * **Door Contact** * When the door opens, the **Comfort** mode is activated for a pre-defined time. * After this time expires, the system switches to **Standby** mode (the duration is set in the **Options** section). * If motion is detected during this time by the motion sensor, **Comfort** mode remains active—indicating someone is in the room. * **Comfort** mode stays active until the next door opening event. * **Window Detector** When triggered, it turns off heating or temporarily switches from **Comfort** to **Standby** mode. * **Glass Controllers (RFSW and RFGS)** * Can be paired for controlling various functions. * Hotel service buttons like **DND**, **MUR**, and **Butler** are interconnected so that their states synchronize across devices. ### **Configuration and Customization** * These behaviors can be customized in the **Options** section. * You can define timers, switching rules, and behavior based on RF input triggers. ### Wiring/Connection examples --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
