Blue Diamond series

 Main features:

2 modifications: Bi-thermal pipe-in-pipe copper heat exchanger or with separate plate DHW heat exchanger

Air draught (open combustion chamber) and forced exhaust models

Till 24kw heating output, till 14.2L/min hot water (DHW) with T=25℃

Integrated 24-hour/week timer allows to set period of times with normal or lower heating temperature within each day of week with the benefits of comfort and low gas consumption

Automatic electronic ignition and ionization flame control

Indication of temperatures, working modes, power level and error codes on the color multifunctional LED-display

Integrated pump, expansion tank, heating safety valve, manometer, automatic air exhaust device

Frost protection: burner and pump will be switch on automatically by danger of freezing. It is allowed to use antifreeze liquid instead of water in the heating system

Steady ignition and work by low inlet gas pressure from 3mbar, full output by inlet gas pressure from 13 mbar and higher

Automatic switch-off by: flame blackout, overheating over 90 ℃, too low pressure in the heating system(<0.5bar), too low DHW flow(<2.5L/min), combustion products exhaust failure, failure in electronic.

Protected service menu for internal functions and working parameters adjusting

PCB is insensitive to the electric polarity and fluctuations of voltage AC 160-242 Volt.

High reliability with integrated switch-mode power supply(SMPS)

Universal main PCB fully compatible with other models of ROC boilers.

Supports smooth control with Open Therm room thermostat from any producer

Supports outdoor temperature driven mode

Flue/air duct φ60/100  1m length included

Supports connection of air ductφ80mm

Supports connection of air ductφ130mm
