Due to variety of LED lamp designs, maximum
number of LED lamps is further dependent on
power factor result when connected to dimmer.
Maximum permitted number of drivers is 250W
divided by driver nameplate power rating.

Main Features:
• Can operate under two-wire connection with no neutral lead or three-wire connection with neutral lead
• Advanced microprocessor control
• Implemented algorithm of smart light source detection
• Soft start function
• Innovative minimum dimming level and startup brightness setting functions
• The Bypass is an extension unit
As a dimmer it operates under the following loads:
• Conventional incandescent and HV halogen light sources
• ELV halogen lamps and dimmable LED bulbs (with electronic transformers)
• 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 3VA using the Bypass (depending on the
type of load)
Trailing edge or leading edge dimming mode can be preset by factory setting to control following types of loads:
• "Trailing edge" for resistive loads
• "Trailing edge" for capacitive loads
• "Leading edge" for inductive loads
Note: factory default version is trailing edge.
• DO NOT install with power applied to device.
• DO NOT expose the device to moisture.

Operation

Pair/delete the pairing with RF+Bluetooth remote
1. Do wiring according to connection diagram.
2. Pair LED controller with RF+Bluetooth remote: please refer to the instruction of the remote that you would
like to pair with.
3. Delete the pairing:
(1) Wire up the LED controller correctly, power on.
(2) Press and hold down the “ Reset” button on the controller for over 3 seconds (or reset power of the device
8 times continuously if the button is not accessible to factory reset the device) until the connected light flashes,
which means well deleted.
Note: factory resetting will restore all configured parameters of the device on the APP to factory default setting.
Pair with smart APP
1. Do wiring according to connection diagram.
2. Download EasyThings APP from IOS APP Store or Android Google Play to your smart phone or tablet by
searching “EasyThings”. (As shown in Figure 1)
3. Enable Bluetooth on your smart phone or tablet. (As shown in Figure 2)

4. ap add button “ on t APP to add device, then choose “Discover devices” to discover
device, then short press the “Reset” button on the dimmer twice (or reset power of the dimmer twice
continuously) to set the device into pairing to APP mode. (As shown in Figure 3 & Figure 4 & Figure 5)
Run Easythings APP, t ” he
Note: multiple dimmers can be discovered by the APP at the same time.
5. Once the device/devices are discovered, tick the device/devices and tap “Save” button, the
will be added successfully. (as shown in Figure 6)

Set Minimum Brightness
Step 1: adjust the brightness of connected
load to a desired level between 1%-50%.
Step 2: press and hold down “Min. set” key for 3 seconds
until connected load blinks to set the brightness adjusted
in step 1 as minimum brightness, then the load can not be
dimmed below this level.
Minimum Brightness Setting
Delete Minimum Brightness
Step 1: adjust the brightness of connected
load to 100%.
Step 2: press and hold down “Min. set” key for 3 seconds
until connected load blinks to delete the previously set
minimum brightness.
Startup Brightness Setting
Set Startup Brightness
Step 1: adjust the brightness of connected load
to a desired level between 1%-50%.
Step 2: double click “Min. set” key to set the brightness adjusted in
step 1 as startup brightness, then the load will first go to startup
brightness when turned on every time, then drop down to the
brightness before last time turned off.
Note: startup brightness setting function is to avoid the phenomenon that some dimmable LED drivers can not be turned
on after turned off at a very low brightness level. Once setting a startup brightness, if the startup brightness is higher than
the brightness before turned off, the driver will first go to the startup brightness after turned on then drop down to the
level before turned off. If the startup brightness is lower than the brightness before tured off, the driver will directly go to
the brightness before turned off.

The Bypass is a device designed to work with the knob smart dimmer. It should be used in case of connecting LED bulbs
or energy saving compact fluorescent lamps. The Bypass prevents flickering of the LED lights and glowing of the turned
off compact fluorescent lamps. In the case of 2-wire connection, the Bypass allows to reduce minimum power of load
required by the dimmer for correct operation. The Bypass provides powering of the dimmer in case of controlling the low
loads of minimum power down to 3W (for cosφ>0.5).
