ecoMAX 860P

ecoMAX 800P plum regulator pelletowy

ecoMAX 860P is a device made in advanced technology. It controls the combustion process in solid fuel boilers with an igniter. By default, it supports the central heating and hot water heating circuits as well as the mixer circuit. The controller is available in a complete enclosure and in a version with a removable panel enabling installation on the front of the boiler. This latest generation microprocessor controller means for the user:

  • intuitive and simple use
  • many interesting functions
  • unique design
  • TOUCH & PLAY control system
  • attractive display presenting information in the form of readable icons
  • comfort with the support of the ecoSTER remote control
  • comfortable on-line operation of the boiler via the Internet

It has a modular structure, ensuring BUS extension. The controller controls: boiler (burner) operation, supports basic central heating and hot water functions, mixer pump and mixer.
Additional modules enable cooperation with the buffer and mixer systems. In addition, cooperation with the Lambda probe module (ecoLAMBDA) is possible. The controller uses a smart Menu system. The system makes unconnected elements inactive (invisible). This solution allows easy and comfortable use.
