Presentation

MyTek Smart Dimmers are devices designed to meet the common needs envisaged for a dimmer, but also to have further added functions compared to normal dimmers on the market, while maintaining a simple and intuitive use.

This is available in different versions: with 1,3,4 channels, as dimmer, as dimmer + DMX512 option, only as DMX512 dimmer, as dimmer + DL485 option.

Brief description of the operation of the smard dimmer, for more details and as regards the DMX part select the WIKI link below.

Many commercial dimmers reverse the sense of dimming each time the button is pressed, and this can be inconvenient
because the user may have changed or not remember the last command given some time before, so he will have to press and observe the direction of variation and eventually release and press the key again to correct.

With the MyTek Smart Dimmer, the direction of variation (increase / decrease) can be similar to that described above, i.e. reverse the direction of variation with each press, or directly controlled by the user in the desired direction through the way in which the button is pressed.

With the Smart Dimmer, when the button is pressed, the direction is predefined increasing and leaving and pressing again immediately reverses the direction each time, so you know in advance what sense of variation you get.

If you want to go up and then go up again without inversion, just wait a second after the first press to reset the button in the up direction and press again.

If, on the other hand, you want to give a descent command, a short pressure is enough followed immediately by a prolonged pressure during which you descend.

However, it is possible to set the dimmer so as not to automatically switch to the default direction and behave like the other dimmers that remember the last direction.

By keeping the button pressed, you can cycle between a minimum and a maximum or between off and a maximum, with programmable pause at the ends, or select the option to stop at maximum or minimum without cycling.

If desired, it is also possible to have separate up and down commands.

All the brightness variations controlled by LEDs already turned on are usually stored and overwrite the previous memory, but there are cases in which this storage is not desirable, as in the cases of temporary switching on for immediate needs.
Use cases of temporary ignitions:
- you enter a room where you want maximum light immediately (two short and close presses are given)
- you enter a room where someone sleeps and you want sufficient minimum light (you keep the button pressed and release at the desired level)
- you want to immediately bring the level to 50% because it is believed that this level is suitable for the needs of the moment (a short press followed immediately by a prolonged one)

The levels memorized by the button for all the channels are saved as well as all the dimmer parameters set and will not be lost if there is no power supply, instead the on / off status of the various channels is not memorized if there is no power supply.

The commands for temporary ignitions that lead to 50% or maximum work if completed before the end of the automatic ignition ramp, so if this ramp is too fast these commands will not be usable.

To immediately memorize the maximum level starting from off, it can be turned on with the two short and close presses, then when the ramp is complete, a longer pressure is given as to increase.
To immediately memorize the minimum level, starting from off, press and hold to start from zero, release and press again to go down and leave at minimum.

Smart Dimmers come with a standard default setting, but have several configurable parameters that allow you to satisfy even unusual applications for a dimmer.

If you make an error while setting the parameters, you can use the procedure for recovering the default setting.

Settable features

- Push button operation with intuitive basic operation
- Soft or immediate on and off
- Temporary switch-ons without altering the brightness levels in memory
- Possibility to set a separate maximum ON time for each channel
- Possibility to set a separate maximum OFF time for each channel
- Possibility of synchronizing 2/3/4 dimmers of the same unit by connecting the inputs together
- Possibility of synchronizing 2/3/4 dimmers of the same unit with general command to maintain the RGB or RGBW color tone
- Possibility of parallel inputs and outputs (2 + 1 if 3-channel dimmer, or 2 + 2 if 4-channel dimmer), to have double output current
- Possibility to set the maximum ON time for RGB / RGBW or staircase lights with possible shutdowns at settable times
   A) with 50% attenuation for the first 1,2,3 steps and then OFF or leaving low light, or
   B) switching off one channel at a time even leaving 1 or 2 channels on at the end
- possibility of blocking changes in brightness and / or blocking memory changes with a button (useful for condominium stair lights)
- Settable state of the outputs when the supply voltage is restored
- Optional second button for separate UP / DOWN commands
- Stand alone version and home automation version controlled from Domoticz or via DMX512 bus
- Division into same intensity zones to increase fault tolerance for large rooms
- Timed stair light controls with different modes for home and condominium

Examples of possible dimmer applications:

- immediate on / off (parameters 2, 3)
- switching on / off with SOFT ramp (parameters 2, 3)
- switch-ons with maximum time (parameter 5)
- periodic switching on and off to simulate the presence of people in the house (parameters 5, 18, 19)
- flashing with buttons pressed (parameters 2, 3, 6)
- flashing lights or light effects (parameters 2, 3, 5, 18, 19)
- flashing which indicates that the electricity was lost and then returned (parameters 1, 2, 3, 5, 18, 19)
- slowing down controls for elderly people (parameters 4, 6, 7, 8)
- building staircase lights command with fixed memory (parameter 12)
- staircase lights command with switch-off warning (general command with max on times set on the various channels)
    - shutdown notice with shutdown of one channel at a time
    - switch-off notice given by brightness reduction
    - incomplete shutdown that leaves a minimum intensity or a channel on
- staircase lights control with or without switch-off by button, or with time reset, or with time sum at each press
- very slow starts like in the cinema (parameters 2, 3, 4)
- brightness variation in a few steps (parameters 14, 15, 16)
- colored luminous signs or chromotherapy for wellness centers that alternate colors
- more light effects deriving from different control units with outputs in parallel and switched on / off as desired
- more light effects deriving from parallel outputs and activation / deactivation of the effect from buttons or via power supply management
- dimmer control from DL485 network and through Domoticz home automation software
- parallel dimmer inputs to obtain synchronized channels with a single button
- parallel inputs and outputs two by two for driving double currents
- RGB / RGBW color management with single buttons and master button (parameter 13)
- command added to manage UP / DOWN even with two separate buttons
  NB: for the 4-channel RGBW model this function is available only for the
  first 3 channels because there are only 6 input terminals, the fourth channel
  it will no longer be usable or it can be used as a fixed intensity light
  upon energy return with possible maximum ignition time or as a flashing output
- soft start and stop with switch or with clean contact of presence sensor
