The manufacturer provides the following warranty terms: 5 years for the tightness of the heat exchanger, 2 years for other components and efficient operation of the boiler.

ADDITIONAL INFORMATION

  • 5 class according to 303-5:2012 standard
  • Ecodesign certificate
  • Fuel tank located above the heat exchanger
  • Automatic boiler operation
  • The ability to prepare hot water
  • Simple operation and maintenance
  • Horizontal flame exchanger

MAIN COMPONENTS OF THE SET

  • APC K Slim Controller
  • ADAPTIVE CONTROL
  • PID function
  • levelling feet
  • Igniter
  • Pellet burner with automatic cleaning function

FUNCTIONS OF THE APC K SLIM CONTROLLER

  • Highly efficient and effective pellet burner with automatic cleaning function.
  • Reliable operation due to modulation of air blowing with "ADAPTIVE CONTROL" system.
  • Low operating costs, high boiler efficiency, thanks to the boiler exchanger (body) with a horizontal multi-pass flame tube design using economizers.
  • The special design of the heat exchanger allows easy and convenient cleaning of the ducts, making the boiler an appliance that is easy to maintain on a daily basis.
  • The use of the advanced APC K SLIM controller provides simple and intuitive operation of the furnace and self-control of the controller.

FUNCTIONS OF THE APC K SLIM CONTROLLER

  • Innovative ADAPTIVE CONTROL using turbine flow meter for optimal selection of fan and feeder parameters
  • Controlling the igniter
  • Operation based on PID control algorithm - calculation of blowing power based on boiler and flue gas temperature measured at the boiler outlet
  • External feeder control
  • Internal feeder control
  • Blower fan control
  • Controlling the cleaning grate
  • Control of the central heating pump - central heating.
  • Control of the domestic hot water pump - DHW.
  • Smooth control of the mixing valve
  • Controlling an auxiliary pump with the possibility of selecting the type of device (central heating pump, DHW pump, circulating pump, floor pump, overflow pump, boiler cleaning)
  • Buffer handling
  • Preview of the amount of fuel in the tank based on user calibration
  • Software update via USB
  • Built-in valve control module
  • Valve weather control
  • Weekly control
  • Cooperation with room regulators with traditional (two-state) communication, e.g. ST-292v3 and equipped with RS communication, e.g. SPK Lux - cooperates only with regulators from DEFRO distribution. Room regulators are a separate purchase
  • Possibility to connect ST-65 GSM module - allows to control some control functions with a cell phone (only and exclusively from DEFRO distribution) - option at extra charge
  • Possibility to connect ST-505 Ethernet module or WIFI RS module - allows you to control functions, view parameters via the Internet (only from DEFRO distribution) - option at extra charge
  • Possibility to connect two additional valve control modules (only from DEFRO distribution) - option at extra charge
  • Possibility to connect an additional extractor fan control module (from DEFRO distribution only) - option at extra charge
  • Photoresist (flame sensor that controls flame quality)
  • It has thermal boiler temperature protection - STB sensor
  • Has thermal burner protection
  • Temperature sensor for central heating, DHW, valve, return, auxiliary, flue gas and outdoor temperature
