IMPORTANT - Read this first!
Note: To simplify these diagrams, we have not shown the earth cables - but all circuits MUST have the earth cable correctly installed.
We've shown wires in red to indicate that they are new wires, but it doesn't really matter what colour you use.
To protect the module a suitable rated overcurrent protection fuse must be installed on the Live input.
We work hard to keep these wiring guides accurate and up to date and would appreciate any feedback, corrections or suggestions that you may have. Please contact us using our help page or by simply emailing feedback@vesternet.com
This guide shows how to install the Qubino Flush Dimmer Plus module into an existing light switch that has Neutral available.
Qubino Flush Dimmer Plus modules need to be installed in a 3-Wire lighting circuit. This means that unless you have Neutral available at the Wall Switch you’ll likelly install them near the light fitting in the ceiling space - at which point you will be able to use the Neutral wire.
More information about 3-Wire lighting systems is available in APNT-23: Understanding 2-wire and 3-wire Lighting Systems.
For information on how to physically install a Z-Wave module take a look at our guide here.
To know more about how Z-Wave modules work with different switch types make sure to read our guide here.
Standard Lighting Circuit (with Neutral)
Figure 1: A Standard Lighting Circuit (with Neutral)
Your existing wiring will be similar to that shown in Figure 1 but this will be changed slightly when the module is installed.
This type of lighting system uses "Toggle" (latching) switches. These latch in position - for instance when you press the switch to On, the switch physically stays in the On position. These are the standard light switches you'll find already fitted in your home.
The module can also be used with a variety of "Momentary" switch types and configurations. Momentary switches, also known as Retractive or Bell-Push, only remain in the On state while you press them, they return to the Off state when the button is released.
This doesn't mean that you have to keep holding the button to keep the light on. The module's internal controls automatically keep the light on when the button is released.
More information about how the Qubino Flush Dimmer Plus works with different switch types is available here.
We can install the module into the 3-Wire circuit in different ways shown below. We've separated out the diagrams based on the Wall Switch type used.
Qubino Flush Dimmer Plus Connections
The Qubino Flush Dimmer Plus has six terminals to connect it to the electrical wiring:

Toggle or Momentary Switches
This is probably the most common of requirements, you will install the module at the Switch position where it has access to both Permanent Live, Switched Live and Neutral.
Toggle Switches
To retain your existing standard Toggle switches, we can simple install the module as shown in Figure 2.
Figure 2: Standard Lighting Circuit (with Neutral) using the Qubino Flush Dimmer Plus with Toggle switch.
In this case we keep the standard Toggle switch connecting the Switch "L1" to the module's I1 input with the "COM" wire connected to Live. Neutral and Live are wired to N and L terminals respectively.
This gives simple On / Off control of the light from the switches but you will still be able to control the dimming level over Z-Wave if required.
Qubino Flush Dimmer Plus Parameter Setting:
The following parameters need to be set:
- 1 - 1 - enables the dimmer to work with a toggle switch (default is 0 for a momentary switch)
Momentary Switches
For full On / Off and dimming control we can replace the Toggle wall switch with similar styled Momentary switch.
Figure 3: Standard Lighting Circuit (with Neutral) using the Qubino Flush Dimmer Plus with Momentary switch.
A Momentary Switch is wired similar as the Toggle Switch - Switch "L1" to the module's I1 input with the "COM" wire connected to Live. Neutral and Live are wired to N and L terminals respectively.
Qubino Flush Dimmer Plus Parameter Setting:
The following parameters need to be set:
- 1 - 0 - keep as default to work with a momentary switch
Install in Ceiling Rose
Alternatively the module can be installed in the Ceiling Rose providing you have easy access to it and enough space to accommodate the module.
Figure 4: Standard Lighting Circuit (with Neutral) using the Fibaro Qubino Flush Dimmer Plus installed in Ceiling Rose
In this case we install the module in the Ceiling Rose connecting Switch "L1" to the module's I1 input with the "COM" wire connected to Live. Neutral and Live are wired to N and L terminals respectively.
Don't forget to configure the module for Toggle or Momentary switches!
