Dimmer 2

Remotely controlled light dimming module FIBARO Dimmer 2 is designed to work with various types of light sources. It may be connected to two-wire or three-wire configuration so it can operate with or without neutral lead. FIBARO Dimmer 2 can switch or dim connected light source either through radio waves or through the wall switch connected directly to it.

New FIBARO Dimmer 2 is equipped with an algorithm of smart light source detection which makes configuration easier and ensures high compatibility of the device. It may be used as a switch with non-dimmable light sources.

FIBARO Dimmer 2 uses different operating modes to control following types of loads:

• „Trailing edge” for resistive loads (R)
• „Trailing edge” for resistive-capacitive loads (RC)
• „Leading edge” for resistive-inductive loads (RL)

As a dimmer it operates under the following loads:

• 230V operated conventional incandescent and halogen light sources
• 12V operated ELV halogen lamps and dimmable LED bulbs (with electronic transformers)
• 12V operated MLV halogen lamps (with ferromagnetic transformers)
• dimmable LED bulbs
• dimmable compact fluorescent CFL tube lamps
• supported dimmable light sources (power factor > 0.5) with minimal power of 5VA using FIBARO Bypass 2 (depending on the type of load)

Without dimming function it may work with:

• compact fluorescent CFL tube lamps with electronic ballast
• fluorescent tube lamps with electronic ballast
• LED bulbs (power factor > 0.7)
• supported light sources (power factor > 0.5) with minimal power of 5VA using FIBARO Bypass 2 (depending on the type of load)

Installation of the FIBARO Dimmer 2:

1. Switch off the mains voltage (disable the fuse)
2. Open the wall switch box
3. Connect with one of the diagrams below.
4. After verifying correctness of connection switch on the mains voltage
5. Wait around 30s for the calibration process to end, light may blink during the process
6. After successful calibration the device will be turned off by default
7. Add the device to the Z-Wave network
8. Turn off the mains voltage, then arrange the device and its antenna in a wall switch box
9. Close the wall switch box and turn on the mains voltage

• Locate the antenna as far from metal elements as possible (connecting wires, bracket rings, etc.) in order to prevent interferences.
• Metal surfaces in the direct vicinity of the antenna (e.g. flush mounted metal boxes, metal door frames) may impair signal reception!
• Do not cut or shorten the antenna – its length is perfectly matched to the band in which the system operates.

Adding (Inclusion) – Z-Wave device learning mode, allowing to add the device to existing Z-Wave network.

To add the device to the Z-Wave network:

Removing (Exclusion) – Z-Wave device learning mode, allowing to remove the device from existing Z-Wave network.

To remove the device from the Z-Wave network:

FIBARO Dimmer 2 has a built-in Z-Wave network main controller’s range tester.

To test the main controller’s range:

1. Press and hold the B-button until the visual indicator glows violet
2. Release the B-button
3. Press the B-button again, briefly
4. Visual indicator will indicate the Z-Wave network’s range (range signalling modes described below)
5. To exit Z-Wave range test, press the B-button briefly

Z-Wave range tester signalling modes:

• Visual indicator pulsing green – Dimmer 2 attempts to establish a direct communication with the main controller. If a direct communication attempt fails, the device will try to establish a routed communication, through other modules, which will be signalled by visual indicator pulsing yellow.
• Visual indicator glowing green – Dimmer 2 communicates with the main controller directly.
• Visual indicator pulsing yellow – Dimmer 2 tries to establish a routed communication with the main controller through other modules (repeaters).
• Visual indicator glowing yellow – Dimmer 2 communicates with the main controller through the other modules. After 2 seconds the device will retry to establish a direct communication with the main controller, which will be signalled with visual indicator pulsing green.
• Visual indicator pulsing violet – Dimmer 2 does communicate at the maximum distance of the Z-Wave network. If connection proves successful it will be confirmed with a yellow glow. It’s not recommended to use the device at the range limit.
• Visual indicator glowing red – Dimmer 2 is not able to connect to the main controller directly or through another Z-Wave network device (repeater).

The Dimmer 2 responds to commands ALL ON/ALL OFF that may be sent by the Z-Wave controller. ALL ON/ALL OFF commands are usually implemented in the remote controllers using Z-wave protocol, and they are used to issue commands directed to the entire system.

By default, both commands ALL ON and ALL OFF are accepted. Settings may be changed by modifying the value of parameter 11. In this way the user may determine to which commands the device should respond.

FIBARO Dimmer 2 is equipped with a B-button, which allows to use the MENU mode and additionally perform the following actions:

1x click:

• alarm mode cancellation (flashing alarm)
• exit the error mode
• select the desired MENU option (if MENU mode is active)

3x click:

• send the Node Info Z-Wave command frame (adding/removing)

Holding:

• enter the MENU mode (confirmed by the LED indicator)

Momentary switch (after releasing the switch a spring automatically pushes back and disconnects the switch):

• Turning the light ON/OFF: change the position of switch no. 1. The Dimmer 2 will be activated always at previously set brightness level.
• Brightening/dimming the light: hold switch no. 1 down. When the switch is held down, the Dimmer 2 will always reach the extreme value of 1% or 99%.
• Turning the light ON completely: fast double-click switch no. 1. The Dimmer 2 will set the load at 99%.

Toggle switch (operates as a two-position switch, it has no spring that would set one position of the switch):

• Turning the light ON/OFF: toggle switch no. 1. The Dimmer 2 will be activated always at previously set brightness level.
• Turning the light ON completely: toggle twice switch no. 1. The Dimmer 2 will set the load at 99%.

FIBARO Dimmer 2 has a MENU with each position indicated by the specified LED indicator colour.

In order to enter the menu press the B-button and hold for at least 2 seconds. While the B-button is still pressed, LED indicator colour will change in the following sequence:

• BLUE – initiate the load calibration procedure
• RED – load calibration procedure with FIBARO Bypass 2
• WHITE – activate turning the load on/off using the B-button
• GREEN – reset the energy consumption data memory
• VIOLET – initiate the Z-Wave network range test
• YELLOW – reset the FIBARO Dimmer 2 to factory defaults

Release the B-button to choose the desired function and confirm your choice with the B-button click.

Dimmer 2 is equipped with an algorithm of smart light source detection. Depending on the connected type of light source, it automatically adjusts an optimal control mode (leading edge for inductive loads, trailing edge for capacitive or resistive loads). The procedure of learning the light source type is called calibration.

Calibration automatically adjusts maximum and minimum light levels (parameter 1 and 2). However, the installer is obliged to verify the proper operation of the device, according to control modes description. There is a 10% probability that calibration settings will require a manual correction. In a 2-wire connection for loads other than resistive parameter 1 settings must be adjusted manually.
Calibration procedure is performed always after removing the device from the Z-Wave network. If the device is not included, after each power on/off calibration will occur. For the included device, calibration is performed in accordance with the parameter 35 settings.

Calibration may be forced:

• by setting parameter 13 to 1 or 2 (without/with FIBARO Bypass 2)
• through triple clicking and holding the main light switch (each hold for more than 5 seconds)
• by selecting the appropriate MENU option using the B-button (see „Operating the device” on page 12)

By default, calibration is performed without FIBARO Bypass 2. In case of connecting the Bypass 2, it is required to force the appropriate calibration procedure using B-button menu or through parameter 13. The device saves the last calibration enforcement mode (with or without Bypass 2).

The result of calibration will be confirmed with the LED indicator glowing in one of the following colours:

• GREEN – Light source recognized as dimmable, dimming levels set, brightness may be controlled using the S1 switch.
• YELLOW – Light source recognized as non-dimmable, possibility to turn ON/OFF connected light with default parameters settings.
• RED – Calibration procedure failed. Possible reasons: lack of connected load or connected light source exceeds maximum power, which may be controlled by the Dimmer 2.
• BLINKING RED – Calibration procedure failed. Possible reasons: installation failure or damaged load (causing activation of the overcurrent protection).

After adding the Dimmer 2 to the network, it will be represented in the FIBARO Home Center controller by the following icon:

Dimming/brightening is performed by moving the slider. The current status of the Dimmer 2 is shown on the bar indicator.
Turning the device ON/OFF – ON and OFF icons are used for setting the last saved state or turning off the Dimmer 2.

Reset procedure erases memory of the device, including all information on the Z-Wave network and the main controller.

Resetting the Dimmer 2:

1. Disconnect the power supply
2. Remove the Dimmer 2 from the wall switch box
3. Connect the power supply
4. Locate the B-button on the housing
5. Press and hold the B-button to enter the menu mode
6. Wait for the visual LED indicator to turn yellow
7. Quickly release and click the B-button again
8. After few seconds the device will be restarted, which is signalled with the red LED indicator colour
9. The device enters the calibration mode

FIBARO Dimmer 2 allows for the active power and energy consumption monitoring. Data is sent to the main Z-Wave controller, e.g. Home Center. Measuring is carried out by the most advanced micro-controller technology, assuring maximum accuracy and precision.

Electric active power – power that energy receiver is changing into a work or a heat. The unit of active power is Watt [W].

Electric energy – energy consumed by a device through a time period. Consumers of electricity in households are billed by suppliers on the basis of active power used in given unit of time. Most commonly measured in kilowatt-hour [kWh]. One kilowatt-hour is equal to one kilowatt of power consumed over period of one hour, 1kWh = 1000Wh.

Resetting consumption memory:

Dimmer 2 allows to erase stored consumption data in three ways:

• By resetting the device (see „Operating the device” on page 12).
• Using functionality of a Z-Wave controller (see the controller’s manual).
• Manually clearing the data using the following procedure:

1. Make sure that the device is connected to the power supply
2. Press and hold the B-button for a few seconds, until LED indicator glows GREEN
3. Release the B-button.
4. Press the B-button briefly
5. Energy consumption memory has been erased

Table of power measurement accuracy:

* Measurements in this case are only illustrative, returned values may differ from the actual measurement. In the case of reporting incorrect values change the values of parameters 58 and 59.

The Dimmer 2 features remote software update (initiated by the main controller). Update status is signalled by the LED indicator with cyan colour:

• slow blinking – transferring data via Z-Wave and saving to the flash memory
• fast blinking – copying data from the external memory to the memory of the microcontroller

FIBARO System allows user to set response of devices to alarm situations (response to data-frames ALARM_REPORT and SENSOR_ALARM_REPORT). Dimmer 2 responds to the following types of alarms:

• General Purpose Alarm – GENERAL PURPOSE ALARM
• Smoke Alarm – ALARM CO2, ALARM CO, ALARM SMOKE
• Water Flooding Alarm – ALARM WATER
• Temperature Alarm – ALARM HEAT

Alarm data-frames are sent by devices that are system sensors (e.g., flood sensors, smoke detectors, motion detectors, etc.).

The device may respond in the following manner to received data-frames (settings are configured in configuration parameters, see „Advanced parameters” on page 22):

0 – DEACTIVATION – the device does not respond to alarm data frames
1 – DIMMER 2 ON – the device turns on after detecting an alarm
2 – DIMMER 2 OFF – the device turns off after detecting an alarm
3 – ALARM FLASHING – the device periodically changes its status to the opposite when it detects an alarm (lights on/off alternately)

Description of error messages of the Dimmer 2:

Events result from installation flaws, faulty light source operation or incorrect manual changes in advanced configuration. The device may stop responding to user’s commands and actions, leaving the light source off. Message with information about the type of error is sent by default (using Z-Wave network).

Error messages:

• OVERTEMPERATURE ERROR
  Dimmer 2 features self-temperature measurement function. In case of reaching critical temperature, the load is turned off and the gateway receives an information about exceeding maximum temperature of the module.
• LOAD ERROR
  Dimmer 2 is equipped with functionality of detecting the burnt out bulb. In case of such situation, Dimmer 2 sends the notification about load failure. Described function is not available for values of parameter 58 different than 0.
  Power variation is detected in accordance with the settings of parameters 15 and 16.
  Example:
  Parameter 15 set to 30%.
  Parameter 16 set to 5 seconds.
  Dimmer 2 will detect the change of load at the moment of power variation by 30% compared to standard power consumption (measured during the calibration) and after 5 seconds from brightness level stabilization.
  This function is available only in a control mode compliant with the mode recognized during the calibration (parameter 14 set to 1).
  Appearing of an error may be the result of not connecting the load. It may suggest burning out all of the loads connected to the Dimmer 2.
  Damaged load should be immediately replaced. After connecting the new load, FIBARO Dimmer 2 will return to normal operation.
• SURGE ERROR
  Appearing of an error may be the result of electrical surges, incorrect load control (inductive load controlled in trailing edge mode) or connecting the prohibited type of load.
• OVERCURRENT ERROR
  Appearing of an error may also be the result of rapid powering on the load. It may also occur if the soft-start functionality is disabled (parameter 34 set to 0) or as a result of the short circuit.
  If parameter 37 is set to 1, the device will automatically try to turn on again.
  If described error has been caused by the rapid powering on the load, then FIBARO Dimmer 2 will return to normal operation after reenabling.
  After three unsuccessful automatic tries of turning on the load, Dimmer 2 will stay in OVERCURRENT error mode (module turned off). In such situation, it is required to remove the failure (possible short circuit in the installation.) Otherwise, it is recommended to set the long soft-start (parameter 34 set to 2).
• OVERLOAD ERROR
  Appearing of an error is a result of connecting receivers with too much power consumption. In this case FIBARO Dimmer 2 will automatically turn off the lighting.
  It is required to reduce power consumption of connected load (e.g. by reducing the number of receivers) and turn on the light source again by the wall switch or a Z-Wave command.
• VOLTAGE DROP ERROR
  Appearing of an error in a 2-wire connection may be the result of mains voltage drop or a too high brightness level of the light source.
  If parameter 37 is set to 1, the device will automatically try to turn on again.
  Voltage drop error suggests that parameter 2 value should be reduced until disappearing of the failure. You can also recalibrate the load using parameter 13.
  After three unsuccessful automatic tries of turning on the load, Dimmer 2 will stay in VOLTAGE DROP error mode (module turned off).
• HARDWARE FAIL ERROR
  Appearing of an error may be a result of serious hardware failure of the Dimmer 2. In this case the Dimmer 2 sets the maximum brightness level and the LED visual indicator starts blinking in red. All external actions (Z-Wave commands, pressing the switches, menu settings) will be ignored.
  We recommend disconnecting the device from the power supply and contacting the customer service or to initiate the guarantee procedure.
  This error may also appear as a result of enabling the Dimmer 2 without load connected to the output in 3-wire connection. It is not a dangerous situation. We recommend disabling the fuse, connecting the load and enabling the fuse again.

Association (linking devices) – direct control of other devices within the Z-Wave system network e.g. Dimmer, Relay Switch, Wall Plug, Roller Shutter or scene (may be controlled only through a Z-Wave controller).

FIBARO Dimmer 2 allows for the associations of five groups:

1st Association Group „Lifeline” reports state of the device. Main Z-Wave+ network controller should be added to this group. The „Lifeline” group can handle only one device. It is not recommended to modify this group.
2nd Association Group „On/Off (S1)” is assigned to switch no. 1. Sends BASIC command class frame according to the state of the device.
3rd Association Group „Dimmer (S1)” is assigned to switch no. 1. Sends MULTILEVEL SWITCH command class frame. Allows sending dim/brighten command to associated devices.
4th Association Group „On/Off (S2)” is assigned to switch no. 2. Sends BASIC command class frame according to the state of the device.
5th Association Group „Dimmer (S2)” is assigned to switch no. 2. Sends MULTILEVEL SWITCH command class frame. Allows sending dim/brighten command to associated devices.
