3. Product Overview
3.1. Zamel RWS-211 J/N Wireless Switch
The RWS-211 J/N is a 1-channel wireless power switch designed for surface mounting. It allows remote control of lighting, ventilation, heating, irrigation, and other receivers. It features a robust IP56 enclosure, making it suitable for various environments.
This image illustrates the versatility of the RWS-211 J/N wireless switch, demonstrating its use in controlling outdoor gates, air conditioning units, and garden lights. The remote control is shown interacting with the switch to manage these devices wirelessly.
3.2. Zamel P-257/2 2-Channel Remote Control
The P-257/2 is a compact, battery-operated 2-button radio transmitter. It is used to control receivers within the EXTA FREE system, including the RWS-211 J/N. Each button can control a separate channel or function.
This image displays the P-257/2 remote control, highlighting its two distinct buttons for controlling different functions or devices. It is a key component for wirelessly interacting with the RWS-211 J/N switch.
4. Setup
4.1. Mounting the RWS-211 J/N Switch
The RWS-211 J/N is designed for surface mounting. Choose a suitable location, considering the desired range and environmental conditions. Ensure the antenna is positioned for optimal signal reception.
4.2. Wiring the RWS-211 J/N Switch
Before wiring, ensure the main power supply is OFF.
- Open the RWS-211 J/N enclosure.
- Connect the 230V AC power supply to the terminals marked 'L' (Live) and 'N' (Neutral).
- Connect the device to be controlled (e.g., lamp, motor) to the output terminals. The RWS-211 J/N provides a potential-free NO (Normally Open) contact.
- Ensure all connections are secure and properly insulated.
- Close the enclosure, ensuring the IP56 rating is maintained.
This diagram illustrates the electrical connections for the RWS-211 J/N switch. It shows how to connect the 230V AC power supply (L and N) and the controlled load (represented by a lamp) to the switch's output terminals. The remote control is also depicted, indicating its role in wirelessly activating the switch.
4.3. Pairing the Remote Control (Learning Mode)
To enable the RWS-211 J/N to respond to the P-257/2 remote control, they must be paired:
- Apply power to the RWS-211 J/N switch.
- Locate the 'PROGRAMMING' button or jumper inside the RWS-211 J/N enclosure.
- Press and hold the 'PROGRAMMING' button for approximately 2 seconds until the LED indicator on the switch starts flashing. This indicates the switch is in learning mode.
- Within 10 seconds, press any button on the P-257/2 remote control that you wish to pair. The LED on the RWS-211 J/N will flash rapidly and then turn off, confirming successful pairing.
- Repeat for any other remote controls you wish to pair (up to 32 transmitters).
5. Operating Instructions
5.1. Using the P-257/2 Remote Control
Once paired, simply press the assigned button on the P-257/2 remote control to activate or deactivate the connected device via the RWS-211 J/N switch. The remote's red LED indicates transmission and battery status.
5.2. Operating Modes of RWS-211 J/N
The RWS-211 J/N supports two operating modes: bistable and timed. These modes can typically be selected via a switch or jumper inside the enclosure (refer to internal diagram if available).
- Bistable Mode: Each press of the remote button toggles the output state (ON/OFF).
- Timed Mode: The output remains ON for a set duration (1 to 120 seconds) after a remote button press, then automatically turns OFF. The time setting is independent for each channel.
6. Maintenance
6.1. P-257/2 Remote Control Battery Replacement
The P-257/2 remote control is powered by a CR2032 battery, with an estimated life of 3 years depending on usage. When the red LED on the remote appears dim or fails to light during transmission, replace the battery:
- Carefully open the remote control casing.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery, ensuring correct polarity.
- Close the remote control casing securely.
6.2. Cleaning
The RWS-211 J/N switch has an IP56 rating, meaning it is protected against dust ingress and powerful water jets. Clean the exterior with a damp cloth. Do not use abrasive cleaners or solvents. Ensure the enclosure remains sealed after cleaning.
7. Troubleshooting
7.1. Device Not Responding to Remote
- Check if the RWS-211 J/N switch has power.
- Verify that the P-257/2 remote control battery is not depleted (check the red LED indicator).
- Ensure the remote control is paired with the switch. If unsure, repeat the pairing process (Section 4.3).
- Check for obstructions between the remote and the switch.
7.2. Short Operating Range
The specified range of up to 350m (RWS-211 J/N) and 300m (P-257/2) is for open air. Obstacles can significantly reduce the effective range. Consider the following material impacts:
This image illustrates how different building materials can affect the wireless signal range. For example, wood/gypsum causes 5-20% loss, glass 10-20%, brick 10-40%, concrete 40-80%, and metal 50-100%. If experiencing short range, consider the materials between the remote and the switch. The range can be extended using an intermediate transmitter (RTN-01).
