Honeywell FR124-3/4AM-R draught regulator

Honeywell FR124 draft regulator controls the combustion process by changing the air supply to the boiler. The built-in thermostat measures the temperature in the boiler and, according to the set temperature, controls the air supply to the solid fuel boiler via a lever with a chain, opening or closing the air damper. The regulator is compatible with most solid fuel boilers (BURNiT, Wirbel, Viadrus, Buderus, KChM, ZOTA, Atmos, Don, etc.). It achieves significant fuel savings.
