壁挂炉常见解答 采暖炉的维护保养（It is common to answer the maintenance of the heating furnace） 1. Increased water pressure on heating. This is normal phenomenon, water thermal expansion in a closed line, pressure will naturally rise, pipeline water capacity (room), the greater the expansion of the greater the pressure, the greater the setting of the higher the temperature, the greater the pressure of inflation, but when cooled to room temperature, the pressure should restore to 1.2-1.2 bar. 2. The pressure of cooling is lower than that of the original filling. Cb this is normal phenomenon, there is a automatically run the wind (vent valve), in the operation of the heating, and air in the radiator pipe, will be hose to the exhaust valve inside the furnace, the air is automatic discharge, so the pressure after cooling, than the original water filling pressure is reduced. The air in the pipe can be exhausted after repeated discharge and rehydration. Note that if the pressure is still decreasing when it is not running, there may be a drop leak that needs to be examined. 3. Worry about the frequent start of wall hanging furnace, affecting the life span. Dont have to worry about, whether imported or domestic all in 3 minutes time and cooling time detections in the program function, that is to say, after reach the set temperature, must meet two conditions, cb to restart: (1) time for more than 3 minutes downtime; (2) more than 5 ℃ lower water temperature, and the two conditions must meet to restart at the same time. 4. After installation of the thermostat, the button or key on the wall hanging furnace will work. The thermostat controls the room temperature, and how much water is used to heat the room temperature, or the knob on the wall furnace. For example: hanging furnace temperature knob on 9, knob of the thermostat at 20 ℃, the cb will take place at 85 ℃ hot water heating, make the room temperature up to 20 ℃ as soon as possible. If the temperature on the cb button on 0, room tempera
