PELLET CONTROLLER (NEW)
PWC - 2500

Biomass electronic controller PWC 2500 was designed to cover the needs of control and management of pellet burners, biomass stoves and wood stoves.

It is a safe and reliable product that was designed using the latest electronic components and integrated circuits, and was especially focusedf or use in very difficult working environments.

The software was designed tobe flexible for all kinds of burners and stoves, and it is continuously improvedfor even better, more economic and user-friendly use.

Technical Specifications

Controller PWC - 2500 for his control and installation has the following features:

  • LCD display  to display the settings and operating  data with English characters.
  • Led Indicators for direct and continuous flow of information  to inform user and technician.
  • BUTTON A1 - A2 - A3 - A4 for adjusting the desirable temperature of the water circuit, entering and leaving the MENU to configure the operating instructions and system activation-deactivation
  • Security 6A / 230VA protecting device and regional short-circuit systems.
  • Terminal for input of digital and analog sensors.
  • Terminal for output signal for controlling  of regional systems of the unit and the heating circuit.

Settings & Commands

Button A1-A2: They are used for increase or decrease of the boiler’s temperature
Button A3: For entering or exiting from the menu
(press for 3 sec)
Button A4: For the activation or deactivation of
the entire system


*After entering the menu, buttons A1 and A2 are
used for increasing and decreasing the values,
while buttons A3 and A4 are used to select which
value we want to change.
*The “User Menu” has access only on the basic settings
*The “Special Menu” has full access on all settings.
(pressButtons A3 and A4 continuouslyfor 5 sec)



USER: The “User Menu” has access only on the basic settings.
