6. Learn to deal with host malfunction
Air source heat pump (ASHP) mainframe will inevitably fail in operation. At this time, users need not panic and can not move the function keys on the control panel or disturb the mainframe at will. Not only is this useless, but it can also make the failure worse.
When the main engine fails, you can check whether the power is off, whether the manual power switch is not on, whether the fuse is fused, whether the protection device is started, whether the timing function is set.
7. Understand the correct energy-saving methods
Generally speaking, most users use air source heat pump (ASHP) for heating at night when the temperature is relatively low, and they may turn off the mainframe when they do not use it during the day. This is actually dangerous, because the heat generated by the air source heat pump unit is transferred through water as a carrier. If the power is cut off in low temperature environment, the main engine will probably be frozen out. The correct method should be to set the set temperature of the unit to the lowest when the main engine is not needed, so that the unit can guarantee the anti-freezing function, which can effectively solve the problem of energy waste and anti-freezing of the unit.
In addition, the anti-freezing of pipelines is a problem after a long passive blackout. This situation is likely to occur in rural areas. If the blackout lasts a long time, users should take certain measures to prevent the main engine from freezing, open the loops and valves, and drain the water in the pipeline clean. In this way, even if the power is cut off, the pipeline and main engine can be avoided frozen because of the low temperature.
