F. Learn to deal with the host fault
When the air source heat pump host is running, it is inevitable that there will be faults. At this time, the user should not panic and can not move the function keys on the control panel or the host randomly. Because it's not only useless, it can also make the fault worse.
In case of operation failure of the main engine, check whether the power is cut off, whether the manual power switch is not opened, whether the fuse is blown, whether the protection device is started, and whether the timing function is set.
G. Understand correct energy saving methods
Generally speaking, most users use air source heat pump for heating when the temperature is relatively low at night, and may turn off the host when not in use during the day. This is actually very dangerous, because the heat generated by the air source heat pump unit is transferred through water as the carrier. If the power is cut off when it is used in a low temperature environment, the main engine is likely to be frozen. The correct way is to set the set temperature of the unit to the minimum when the main engine is not needed to work, so that the unit can ensure the antifreeze function, which can effectively solve the problem of energy waste and unit antifreeze.
In addition, after a long time of passive power failure, pipeline anti freezing is a problem. This situation is likely to occur in rural areas. If the power is cut off for a long time, users should take certain measures to prevent the main engine from freezing, open the Union and valve, and drain the water in the pipeline. In this way, even if the power is cut off, it can also avoid freezing the pipeline and the host due to low temperature.
