SUPPORTED LOADS
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 LED Adaptor (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 LED Adaptor (depending on the type of load)
Applied load and Dimmer-Control itself may be damaged if the applied load is inconsistent with the technical specifications!
When connecting Dimmer-Control act in accordance with the following rules:
- Do not connect loads greater or less than those recommended,
- Do not connect different types of light sources simultaneously,
- Do not connect the power supply without a load,
- Do not connect more than one transformer with Dimmer-Control output,
- When using magnetic transformer load it with 50% of its nominal power at minimum,
- Minimize number of electronic transformers in a circuit, noises caused by them in electrical grids may affect Dimmer’s operation.
Caution. Dimmer-Control supports only compact fluorescent tube lamps and fluorescent tube lamps with electronic ballast. Do not connect other types of fluorescent lamps!
Dimmer-Control 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)
Note. Some types of the LED bulbs and compact fluorescent lamps are designed to work in leading edge operating mode.

4 LED ADAPTOR
LED Adaptor is a device designed to work with Dimmer-Control. It should be
used in case of connecting LED bulbs or energy saving compact fluorescent
lamps. LED Adaptor prevents flickering of the LED lights and glowing of the
turned off compact fluorescent lamps.
In the case of 2-wire connection, LED Adaptor allows to reduce minimum power
of load required by Dimmer-Control for correct operation. The LED Adaptor
provides powering of Dimmer-Control in case of controlling the low loads of
minimum power down to 5VA (for cosφ>0.5).
- Dimmer-Control was designed to work only with the LED Adaptor. Connecting other devices may cause damage to Dimmer-Control.
- In the case of 2-wire connection do not connect load below minimal power without the LED Adaptor.
- LED Adaptor works only with Dimmer-Control in trailing edge mode. Do not connect the LED Adaptor to the Dimmer operating in leading edge mode.
- LED Adaptor is sensitive to the frequent changes of the state of Dimmer-Control (alternate switching on and off).Significant changes in brightness should not be performed more than once per second.
Device installation:
- Switch off the mains voltage (disable the fuse).
- Connect the LED Adaptor in accordance with Wiring Diagram 3.
- Follow Dimmer-Control installation.
- Force the calibration procedure with LED Adaptor using RED menu position or through setting parameter 13 to 2.

ADDING THE DEVICE
- For toggle switches in default configuration perform six position changes.
- In case of problems related to unknown configuration or type of external switch use the B-button to add/remove.
- While adding Dimmer-Control to the network with connected toggle switch, ensure that all switch contact is open (off). Otherwise it will prevent adding/removing the device to/from the network.
- Removing Dimmer-Control from the Z-Wave network restores all the default parameters of the device, but does not reset power metering data.
- Adding/removing is not possible during the calibration procedure.
- Adding in security mode must be performed up to 2 meters from the controller.
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 manually:
- Place Dimmer-Control within the direct range of your Z-Wave controller.
- Identify switch no. 1 (turns the light on) or the B-button (located on the device’s housing).
- Set the main controller in (security/non-security) add mode (see the controller’s manual).
- Quickly, three times press switch no. 1 or the B-button.
- Wait for the adding process to end.
- Successful adding will be confirmed by the Z-Wave controller’s message.
7 REMOVING THE DEVICE
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:
- Place Dimmer-Control within the direct range of your Z-Wave controller.
- Identify switch no. 1 (turns the light on) or the B-button (located on the device’s housing).
- Set the main controller in remove mode (see the controller’s manual).
- Quickly, three times press switch no. 1 or the B-button.
- Wait for the removing process to end.
- Successful removing will be confirmed by the Z-Wave controller’s message.
- Dimmer-Control will start the calibration process.
Notes:
- Removing the device restores all the default parameters of the device, but does not reset power metering data.
- In case of problems with removing using the S1 switch, use B-button instead (located on the housing).
- If parameter 40 enables scenes for triple S1 click, disable it or use B-button instead to remove the device.
- If parameter 24 is set to 1, use S2 switch instead to remove the device.
OPERATING THE DEVICE
Controlling Dimmer-Control using a switch:
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-Control will be activated always at previously set brightness level,
-
Brightening/dimming the light: hold switch no. 1 down. When the switch is held down, Dimmer-Control will always reach the extreme value of 1% or 99%,
-
Turning the light ON completely: fast double-click switch no. 1. The Dimmer-Control 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-Control will be activated always at previously set brightness level,
-
Turning the light ON completely: toggle twice switch no. 1. The Dimmer-Control will set the load at 99%.
Controlling Dimmer-Control using a command: A LL ON/ALL OFF in non-secure
mode:
The Dimmer-Control 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
(see chapter 15 – Advanced parameters). In this way the user may determine to
which commands the device should respond.
Note. Resetting the device is not the recommended way of removing the device from the Z-Wave network. Use reset procedure only if the primary controller is missing or inoperable.
Resetting Dimmer-Control:
- Disconnect the power supply.
- Remove Dimmer-Control from the wall switch box.
- Connect the power supply.
- Locate the B-button on the housing.
- Press and hold the B-button to enter the menu mode.
- Wait for the visual LED indicator to turn yellow.
- Quickly release and click the B-button again.
- After few seconds the device will be restarted, which is signalled with the red LED indicator colour.
- The device enters the calibration mode.
Controlling Dimmer-Control using the B-button:
Dimmer-Control 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)
MENU mode & visual indications:
Dimmer-Control 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 LED Adaptor
- 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 Dimmer-Control to factory defaults
Release the B-button to choose the desired function and confirm your choice with the B-button click.
CALIBRATION
- Some types of LED and CF lamps are designed to operate in leading edge mode (with conventional dimmers). Information about proper operation mode of the bulb should be included in its manual. In this case you have to manually force the desired operating mode using parameter 30.
- During the calibration procedure, radio connection is disabled and Dimmer-Control does not respond to any commands. It may cause temporary problems with communication in the Z-Wave network. After completing the calibration, communication with the module will be restored.
Dimmer-Control 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 small
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 LED Adaptor)
- by selecting the appropriate MENU option using the B-button (see “Operating the device” on page 12).
By default, calibration is performed without LED Adaptor. In case of
connecting the LED Adaptor, it is required to force the appropriate calibra-
tion procedure using B-button menu or through parameter 13. The device saves
the last calibration enforcement mode (with or without LED Adaptor).
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 Dimmer-Control.
- BLINKING RED – Calibration procedure failed. Possible reasons: installation failure or damaged load (causing activation of the overcurrent protection).
POWER AND ENERGY CONSUMPTION
Dimmer-Control allows for the active power and energy consumption monitoring.
Data is sent to the main Z-Wave controller, e.g. Home Cen-ter. 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.
Caution. Dimmer-Control in the 3-wire connection has the power and energy measurement function. In case of the 2-wire connection this function is available only for load of cosφ ≥ 0.99. In other cases power is estimated and can differ from actual power consumed by the device.
Caution. Dimmer-Control stores periodically (every 5 minutes) the consumption data in the device memory. Disconnecting the module from the power supply will not erase the energy consumption data.
Resetting consumption memory:
Dimmer-Control allows to erase stored consumption data in three ways:
- By resetting the device.
- Using functionality of a Z-Wave controller (see the controller’s manual).
- Manually clearing the data using the following procedure:
- Make sure that the device is connected to the power supply.
- Press and hold the B-button for a few seconds, until LED indicator glows GREEN.
- Release the B-button.
- Press the B-button briefly.
- Energy consumption memory has been erased.

- 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.
Note. Power measurement in the 2-wire connection does not include mains voltage fluctuations within +/- 10%.
ASSOCIATIONS
Association (linking devices) – direct control of other devices within the
Z-Wave system network using the wall switch connect-ed to Dimmer-Control.
The association enables Dimmer-Control to control directly a device included
in Z-Wave network e.g. other Dimmer, Relay Switch, Roller Shut-ter or scene
(may be controlled only through a Z-Wave controller).
- Association ensures direct transfer of control commands between devices, is performed without participation of the main controller and requires associated device to be in the direct range.
- The Dimmer-Control supports the operation of multichannel devices.
The Dimmer-Control provides the association of five groups:
1st Association Group “Lifeline” reports state of the device. Main Z-Wave Plus
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.
Dimmer-Control in 2nd to 5th group allows to control 8 regular or multichannel
devices per an association group, with the exception of “Life-line” that is
reserved solely for the Z-Wave controller and hence only 1 node can be
assigned.
It is not recommended to associate more than 10 devices in general, as the
response time to control commands depends on the number of associated devices.
In extreme cases, system response may be delayed.
Z-WAVE RANGE TEST
The device has a built in Z-Wave network main controller’s range tester.
Note. To make Z-Wave range test possible, the device must be added to the
Z-Wave controller. Testing may stress the network, so it is recommended to
perform the test only in special cases.
Note. Communication mode of the device may switch between direct and one
using routing, especially if the device is on the limit of the direct range.
Follow the below instructions to test the main controller’s range:
- Press and hold the B-button until the visual indicator glows violet.
- Release the B-button.
- Press the B-button again, briefly.
- Visual indicator will indicate the Z-Wave network’s range (range signalling modes described below).
- To exit Z-Wave range test, press the B-button briefly.
Z-Wave range tester signalling modes:
Visual indicator pulsing green – the device 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 – the device communicates with the main
controller directly.
Visual indicator pulsing yellow – the device tries to establish a routed
communication with the main controller through other modules (re-peaters).
Visual indicator glowing yellow – the device 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 – the device does communicate at the maximum
distance of the Z-Wave network. If connection proves suc-cessful it will be
confirmed with a yellow glow. It’s not recommended to use the device at the
range limit.
Visual indicator glowing red – the device is not able to connect to the main
controller directly or through another Z-Wave network device
(repeater).
ERROR MODES
This chapter describes error messages of Dimmer-Control.
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).
- Pressing any of the connected switches or changing state of the device using the controller will exit error mode.
- If parameter 35 is set to 3 or 4, the load will be calibrated again after turning on the load or an occurrence of LOAD ERROR, SURGE or OVERCURRENT error.
Error messages:
-
OVERTEMPERATURE ERROR
Dimmer-Control 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-Control is equipped with functionality of detecting the burnt out bulb. In case of such situation, Dimmer-Control sends the notifi-cation 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-Control 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 Dimmer-Control.
Damaged load should be immediately replaced. After connecting the new load, Dimmer-Control 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 con-necting 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 (pa-rameter 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 Dimmer-Control will return to normal operation after reen-abling.
After three unsuccessful automatic tries of turning on the load, Dimmer- Control 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 Dimmer-Control 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
- After three unsuccessful automatic tries of turning on the load, Dimmer- Control 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 Dimmer- Control. In this case Dimmer-Control 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 proce-dure.
This error may also appear as a result of enabling Dimmer-Control 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.
ADDITIONAL FUNCTIONALITY
Software update
Dimmer-Control 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
Operating alarm data frames
A smart home hub allows user to set response of devices to alarm situations
(response to data-frames ALARMREPORT and SENSOR ALARM_REPORT). Dimmer-
Control 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 chapter 15 – Advanced parameters):- 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)
