When the temperature of the indoor thermostat 2051 is greater than the heating set temperature, the terminal pump 203 stops. In heating mode: SV5 electric two-way valve 204 is in the open state. The working principle of heating floor heating mode is: heat pump heating - switching through the first level of SV1 electric three-way valve 101 - switching through the second level of SV2 electric three-way valve 201 - direct heat exchange through the buffer water tank 202 - the circulation pump 108 is used as a transport for continuous circulation. The control principle of heating floor heating is turned on - when the heat pump host detects When the water temperature of the second temperature sensor 2021 in the buffer water tank 202 is less than the heating set temperature - the heating hysteresis difference, the unit runs and the circulation pump 108 is turned on. When the heat pump main unit detects that the water temperature of the second temperature sensor 2021 in the buffer water tank 202 is greater than the heating set temperature, the unit stops and the circulation pump 108 keeps running. The heating floor heating pump 208 is controlled: the start conditions are as follows: when there is a demand for heating floor heating, the floor heating pump 208 is turned on. When special antifreeze is used, the ambient temperature is greater than four degrees and the floor heating water temperature is less than two degrees, the floor heating pump 208 is turned on. When the special antifreeze is turned off, the ambient temperature is greater than four degrees or the floor heating water temperature is greater than ten degrees, the floor heating pump 208 is turned off. When the heating floor heating mode is selected; the SV3 electric three-way valve 207 is controlled, and when the floor heating temperature sensor 2111 is used When the detected temperature is less than the floor heating set temperature - the floor heating hysteresis, the SV3 electric three-way valve 207AB-A is turned on and the floor heating pump 208 is turned on. When the floor heating temperature sensor 2111 detects a temperature greater than the floor heating set temperature, the SV3 electric three-way valve 207AB-B is turned on and the floor heating pump 208 keeps running. This cycle repeats. The working principle of the swimming pool mode is as follows: heat pump heating - switching through the first level of the SV1 electric three-way valve 101 - switching through the second level of the SV2 electric three-way valve 201 - through the swimming pool heat exchanger 301 - the circulation pump 108 acts as a transport for continuous circulation. The constant temperature control principle of the swimming pool mode is as follows: when the heat pump main unit detects that the water temperature in the swimming pool heat exchanger 301 is less than the swimming pool set temperature - the swimming pool hysteresis, the unit runs and the circulation pump 108 is turned on.Off - When the heat pump unit detects that the water temperature detected by pool temperature sensor 3011 in pool heat exchanger 301 is greater than the pool's set temperature, the unit shuts down, and circulation pump 108 continues to run. Pool mode constant temperature control: The conditions for turning on pool pump 304 are: when there is a pool demand, pool pump 304 turns on. During special antifreeze mode, if the ambient temperature is less than 4 degrees and the pool water temperature is less than 2 degrees, pool pump 304 turns on. When special antifreeze mode is off, if the ambient temperature is 4 degrees or the pool water temperature is greater than 10 degrees, pool pump 304 turns off. In pool constant temperature mode, SV4 electric three-way valve 302 controls the temperature. When the pool temperature sensor 3011 detects a temperature less than the pool's set temperature minus the hysteresis, SV4 electric three-way valve 302AB-A opens, turning on pool pump 304. This cycle continues until the pool temperature exceeds the pool's set temperature, at which point SV4 electric three-way valve 302AB-B opens, and pool pump 304 continues to run.
