1, the function switch is arranged in the water level, when the detected temperature down to 5 degrees, hanging furnace will start automatically, the heating water temperature and heating to automatically shut down 42 degrees.

2, will be able to switch in the winter mode, temperature knob settings to the lowest position, maintaining low temperature operation to ensure that the boiler will not be frozen. ZELLEN gas hanging stove has the duty to antifreeze function, function settings file in hot water, when the water temperature is 5 ℃ start automatically. The factory does not advocate this approach, the reason is not safe. If the room heat preservation is not good, when the wall hanging furnace measured up to 5 ℃, the distal end of the radiator may have to minus temperature (Re Min resistance can only measure the furnace temperature), although this method is the provincial gas, but also the most prone to problems. Indoor air leakage remote heating is frozen, resulting in pipeline is frozen, circulation, and the development of wall mounted boiler was frozen, such cases have occurred, so before the indoor air leakage problem is not solved, the antifreeze is not safe. Low temperature operation of antifreeze, is to use the minimum temperature heating method, ensure boiler radiator is not cold, relatively safe, but the cost of gas. The user can according to their own home insulation condition and to eliminate the hidden trouble of leakage, choose antifreeze method.
