PROTON BUFFER CONTROLLER 445.00 for 5th Class and EcoDesign Loading Furnace Boiler

BASIC DESCRIPTION:

The PROTON BUFFER temperature controller is designed to control the operation of C.O. boilers CLASS V equipped with a forced draft blower or exhaust fan; it stabilizes its temperature by smoothly regulating the fan speed, performs boiler purges (to remove excess gases produced during combustion), and protects the C.O. system from water overheating. An advantage of this controller is that, in addition to managing the central heating pump operation, it also controls the pump charging the heat buffer.

FUNCTIONS:

• smooth regulation of the exhaust fan speed
• control of the C.O. circulation pump
• control of the buffer charging pump
• support for REMOTE CONTROL or room thermostat
• anti-freeze system below 5°C
• anti-stagnation system for the C.O. pump
• possibility to set maximum and minimum blower speeds (works with different types of blowers)
• gradual blower start-up from minimum to maximum speed
• operating modes: summer, winter, buffer priority, no buffer
• fuel shortage control
• clear LED display
• easy-to-use menu
