Frequently Asked Questions - GW14798 Gewiss

How to install the GW14798 receiver?

The receiver must be installed by qualified personnel in a standard flush-mounting box on a Chorus support. It connects to the KNX/EIB bus via the supplied terminal (red wire to +, black to -). Maintain a distance of at least 4 mm between bus cables and electrical cables.

How to pair an RF remote control with the receiver?

Set the rear rotary selector to position 1 (or the desired channel). The front LED lights up red. Press the button on the remote control you want to pair. The LED turns off and then on again after 5 seconds to memorize another transmitter. Repeat for each channel, then return the selector to position 0.

How many RF transmitters can be paired per channel?

Up to 4 different RF transmitters per EIB channel, i.e., 32 transmitters total for 8 channels. If the LED blinks red during learning, it means the channel memory is full.

How to delete all RF pairings?

Set the rotary selector to position 9. The LED blinks yellow for 10 seconds, then remains steady yellow: all pairings are deleted. To cancel, turn the selector before the blinking ends.

What functions can be configured on each channel?

Available functions are: on/off switching, dimming control, blind/curtain control, scenes, priority control, command sequence (channels 1-4), 8/16 bit value (channels 5-8), and sensor alarms.

How to test an EIB channel operation?

Set the rotary selector to the desired channel position (1 to 8) and press the front button. The receiver sends a command on the bus (e.g., On for switching). This allows checking wiring and identifying channels.

What to do if the receiver stops responding?

Check the KNX/EIB bus power. After a power outage, the device becomes operational again about 60 seconds after restoration. If the problem persists, check connections and ETS configuration.

Can this receiver be used with wired switches?

Not directly. The receiver only works with RF transmitters from the Chorus range (remote controls, control units, RF input modules, detectors). For wired switches, an RF input module (e.g., GW14813) is required.

What is the maximum radio range?

Typical range is about 30 meters indoors, but may vary depending on obstacles (walls, metal). Install the receiver in a central position away from electromagnetic interference sources.

How to configure the receiver with ETS software?

The receiver must be programmed with ETS (Engineering Tool Software) to assign a physical address and configure communication objects for each channel. Refer to the Gewiss technical manual for parameterization details.

Summary

The EIB 8 channel RF Receiver - flush-mounted, allows the Chorus system RF command and control devices to communicate with a KNX/EIB system, which hence allows the Building Automation EIB system to be extended using RF command devices.

The EIB System receiver is an 8 channel input interface function to all effects. Up to 4 different RF command sources (transmitters) can be connected to each channel which manages a total of 32 channels of the RF remote controls (GW 20 963), RF push-button panels (e.g. GW 14 803), IR with twilight switch RF movement detector (e.g. GW 14 811), 2 RF channel input modules (e.g. GW 14 813), etc.

The receiver is powered by the bus line. The front button is used to test EIB channels identified by the rear rotating switch position (1-8). Turing the rear rotating switch to a position (1-8), the radio receiver is able to learn the connections with the RF command devices. The configuration status is indicated by the front LED.

The receiver is able to send the bus, for each channel, the battery conditions of the last RF source that transmitted so that they can be replaced before they are fully depleted.

The device is fitted inside a standard flush-mounted box, mounted on Chorus supports in the space of two modules.

This device must be configured using the ETS software. Each channel can perform one of the following functions, by choice:

Functions

ON/OFF SWITCHING

This switches the KNX/EIB actuator output.

Two buttons on the RF remote control, a button on the RF push-button panel, a RF timed-thermostat (e.g. GW 14 841) or a RF bidirectional (e.g. GW 14 851), a 2 RF channel input module or an IR with twilight switch RF movement detector can be used for this command.

DIMMING MANAGEMENT

This allows you to manage the lighting fixtures connected to a KNX/EIB dimmer. Each individual dimmer channel can be controlled using one button on the RF push-button panel, two buttons on the RF remote control or a 2 RF channel input module.

• long pressure (>0.5s) : regulation of the light intensity;
• short pressure (≤ 0.5s) : total On or Off option.

AWNING AND SHUTTER MANAGEMENT

This activates motorised awnings or shutters connected to a KNX/EIB actuator motor command.

Each individual awning or shutter function can be controlled using one button on the RF push-button panel, two buttons on the RF remote control or a 2 RF channel input module.

• long pressure (>0.5s) : shutter movement;
• short pressure (≤ 0.5s) : stop, if the shutter is moving; regulation of the laths if the shutter is at a standstill and only if the actuator is set to "blinds" mode.

SCENE MANAGEMENT

This allows you to manage a scene. The scene can be controlled with a button on the RF push-button panel or RF remote control or with an 2 RF channel input module, with the possibility of sending two different values for each channel.

• short pressure (≤ 3s) : activation of the scene;
• long pressure (>3s) : scene saving.

SEND PRIORITY CONTROLS

Using the buttons on the RF push-button panel or RF remote control or a 2 RF channel input module, it is possible to override the status (fixed ON or OFF, regulated at choice) of a KNX/EIB device. This function can be used, for instance to keep lights ON, ignoring other switch-off commands.

SEQUENCE COMMANDS

This permits up to 4 commands to be sent simultaneously with 1bit/1byte format for actuations, to send values, etc. Each command is linked to two different values with the same format which are sent according to the RF command received.

This function can only be set for channels 1 through 4.

8/16 BIT VALUE

This permits a command to be sent with 8/16 bit format to send, for example, a setpoint, etc. Each command is linked to two different values with the same format which are sent according to the RF command received.

This function can only be set for channels 5 through 8.

ALARMS

This function can be used to send the bus sensor commands which have a potential-free contact in output, connected to the 2 RF channel input module. Therefore, shutters can be automatically lowered in the event of rain or awnings closed in the event of wind.

Commands sent to the KNX/EIB bus

According to the type of RF device used, on the action performed on it and the function set on the receiver KNX/EIB channel, the receiver will send the KNX/EIB bus a precise command, as seen in the charts below.

KNX/EIB channel test

After the 8 channel EIB RF receiver - flush-mounted is set using ETS software, the front button can be used to test EIB channel operations.

Turn the rotating switch to a value between 1 and 8 on the receiver and press the front button. A command will be sent to the bus that identifies the linked EIB channel as shown in the following charts. This function may be useful in testing correct device operations and to find the EIB channels to be linked to RF commands during their configuration. When the rotating switch is on 0, the front button does not run any function.

Rotating switch position 1 2		3 4 5	6 7 8
Concerned communications object		n. 0 n.	6 n.1	2 n. 18	n. 24	n. 30 n.	36 n.	42
RF-EIB channel configuration	switching	Send "ON" to the concerned communications object
	priority control	Send "override on" to the concerned communications object
	dimmer	Send "ON" to the concerned communications object
	shutters	Send "move shutters down" to the concerned communications object
	sensor alarms1	Send "ON/OFF" to the concerned communications object
	scene	Send "run scene A" to the concerned communications object
	command sequence/8/16 bit values	Send "value 1" to the concerned communications object

(1) The ON or OFF value depends on how the sensor alarm status was set (direct or reverse) in the ETS configuration.

WARNING: the installation of the device must be exclusively done by qualified personnel, following the regulations in force and the guidelines for KNX/EIB installations.

Warnings for KNX/EIB installations

1. The length of the bus line between the 8 channel EIB RF Receiver and the power supply unit must not exceed 350 metres.
2. The length of the bus line between the 8 channel EIB RF Receiver and the most distant KNX/EIB device must not exceed 700 metres.
3. If possible do not create ring circuits so as to prevent undesirable signals and overloads.
4. Keep a distance of at least 4mm between the individually insulated cables of the bus line and those of the electric line (figure C).
5. Do not damage the electrical continuity conductor of the shielding (figure D).

WARNING: the unused bus signal cables and the electric continuity cable must never touch powered elements or the grounding cable!

Good wireless connection recommendations

• Install the receiver in a "central" position in relation to the various RF devices it must receive commands from.
• Install the receiver as far as possible from all sources of electromagnetic disturbances, such as electrical motors, electricity meters, electrical appliances.
• Do not install the receiver near or behind metal surfaces.
• Do not install the receiver inside metal electrical panels or junction boxes mounted inside reinforced concrete walls.

Electrical connections

Figure B shows the electrical connections diagram.

1. Connect the bus cable's red wire to the terminal's red connector (+) and the black wire to the black connector (-). Up to 4 bus lines (wires of the same colour in the same connector) can be connected to the terminal (figure E).
2. Insulate the screen, the electrical continuity conductor and the remaining white and yellow wires of the bus cable (should a bus cable with 4 conductors be used), which are not needed (figure D).
3. Insert the bus connector into the special feet of the device. The fastener guides determine the direction it should be inserted. Insulate the bus terminal using the relative cover, which must be screwed onto the device. The cover guarantees that the power cables and the bus cables are separated by at least 4mm (figure F).

RF channel learning process

To memorise the combinations between the RF transmitter devices and the receiver, please proceed as follows:

1. Turn the rear rotating switch on the receiver to position 1: the front LED will come ON (red) to indicate that the receiver is ready to receive a learning RF message to be memorised.
2. Follow the instructions for the device that must be combined to generate the required command message.

The LED will go OFF to indicated that the RF message has been learnt.

1. After 5 seconds the LED will come back ON and it is possible to memorise another RF message, repeating the procedure 2 above. If the LED flashes (red), this means that the memory is full (4 transmitters memorised on each channel) and it is therefore necessary to use another channel.
2. If necessary, turn the rotating switch to the next position (2, 3 ... 8) and repeat procedure 2 to memorise the other transmitters.

WARNING: do not turn the rotating switch to position 9.

1. After memorising all the required transmitters, turn the rotating switch to position 0 for standard functions In this position the receiver LED flashes green briefly each time it receives a message from any of the learnt RF devices.

Cancelling learnt RF channels

To cancel the combinations memorised on the various RF channels, turn the rotating switch to position 9: the front LED will flash for 10 seconds (yellow) and then remain ON (yellow) to indicate that all the channel combinations have been cancelled.

To interrupt the cancellation procedure, turn the selector switch to another position before the LED stops flashing.

WARNING: it is not possible to perform selective cancellations: the cancellation operation requires new learning of all the required RF transmitters.

Completing installation

Insert the device in a Chorus support, making sure the EIB channel test front button is to the left.

Complete the installation with other Chorus devices or hole covers and fix it to the relative container (flush-mounted box, wall-mounted box etc).

Apply the finish plate.
