CHARACTERISTICS OF DEFRO CALORI BOILER

• 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
