This single-channel dimmer is designed for smooth control of electrical load (non reactive load). It has 3 input channels for connecting buttons and reed switches. MOSFET type.

CAUTION! All work related to the installation, connection, setting up, service and support must be carried out by qualified personnel with sufficient skills and experience in working with electrical equipment. To avoid the risk of fire, electric shock, damage to the system and/or personal injury, the system installation and assembly must be performed in accordance with the instructions listed below:

  • all connectivity work must be carried out with the power turned OFF;
  • use appropriate tools and personal protection against electric shock;
  • do not use damaged cables, wires and connectors;
  • avoid folding the cables and wires;
  • do not apply excessive force to the wires by kinking or pressing them too hard: the inner conductors of the cables and wires may get stripped or damaged;
  • do not use the power socket with poor contacts to connect;
  • do not exceed the load limit parameters specified in the manual;
  • the supply conductors wire section is subject to the specifications for current density limit, insulation type and wire material. Light section can result in cable overheating and fire.

When the power is on, NEVER:

  • connect/disconnect the connectors;
  • open modules and sensors.

HW settings

Name Type, range SUBID Default Description
def integer 0-250 1 100 The default brightness level in case of a power reset (1..250). Example: def=250
min integer 0-100 1 0 Minimum dimming level, example: min=10
max integer 0-100 1 100 Maximum dimming level, example max=95
start integer 0-100 1 0 The Start function is used for lamps that lack the minimal voltage to get turned on. If the set value is lower than the start value, the lamp is turned on at the start value and them the light is dimmed down to the set level. Example: start=60
force integer 0-100 1 10 Time duration of the starting value (measured in milliseconds). Example: force=20
runtime integer 0-60000 1 1000 Runtime is the speed of changing the brightness from ‘min’ to ‘max’ (measured in milliseconds). Example: runtime=1000
protect integer 0;1 1 0 Overload Protect. 0(off); 1 (on), example: protect=0
offset float(+/- 0…39) 30 0 sensor values offset;

For example, offset is -3.8 :

mode string 98 disabled Frequency of pulse-width modulation in Hz for item with direct current.
  • dc100 – 100Hz
  • dc200 – 200Hz
  • dc400 – 400Hz
  • dc800 – 800Hz

Example: mode='dc400'

dm char 98 'g' Each char is responsible for the type of a particular channel
  • 'g' – use like halogen dimmer-lamp
  • 's' – Soft Switch, lamp, when on/off power is supplied/deenergised smoothly (500msec)
  • 'k' – Switch, lamp, when on/off power is supplied/deenergised immediately
  • 'l' – LED Function, dimmable LED lamps
  • '-' – Channel disabled
  • '+' – Regular channel

Example: dm='s'

in char[3] 98 'BBB' Each char is responsible for the type of a particular channel
  • 'B'-Button, a bell type;
  • 'C'-Inverted button, inversebutton of a bell type (for normally-closed);
  • 'D'-Backlit button, illuminated button;
  • 'E'-Inverted backlit button, inverse illuminated button;
  • 'S'-Switch, fixed switch;
  • 'K'-Contact, reed contact;
  • 'H'-Inverted contact, inversereed contact;
  • '-'-none, nothing is connected.

And you can also connect one temperature sensor:


Example: in='BCB'
