Innovative new electronic gas and air modulation system, providing the following benefits: Accurate electronic modulation of gas and air for clean, low emission combustion. Wide modulation range of 1:6 (16%) provides a low minimum output for use in properties with small heat loads or where multiple heating zones have been used. Self-adjusting range rating function, which learns the maximum heating requirement of the system without the need for setting, ensuring the most efficient mode of operation. Assured Comfort (back-up mode) - in the unlikely event of a combustion fault, the boiler will revert to the last known operating condition to provide a degree of heat and hot water until the fault is fixed.
