  • Page 5: System Schematic

    1. System Schematic With innovation technology, Midea combine Air to Air and Air to Water in the same multi system, providing an all-in-one solution for demands of space cooling, space heating and domestic hot water. Scenario 1:Use of multi-split air conditioners Indoor unit: cooling (dehumidifying), heating, fresh air, hydraulic module: domestic hot water, space heating There is a mode conflict among cooling (dehumidifying), heating and the space heating.
  • Page 6 Scenario 2:Only used for space heating The outlet water temperature of the hydraulic module is set by using the user controller, and the outlet water temperature is set in accordance with different loads (floor heating or heating radiator) or room temperature. When the outlet water temperature reaches the set temperature, the hot water generator will shut down.
  • Page 7 Scenario 3: Space heating and domestic hot water The domestic hot water is supplied by the domestic hot water storage tank connected to the hot water generator, the hot water tank is connected by electric 3-way valve and feedwater line, the main control feed tank has reserved temperature sensor and immersion electric heater interfaces (achieving disinfection and EA heating functions), there is no water tank by default in the system, and they needs to be started by dialing on the main board.
  • Page 8 Scenario 4: Space heating, space cooling (reserved) and domestic hot water A floor heating loop and a fan coil unit are used for space heating, and a fan coil unit is used for space cooling. The domestic hot water is supplied by the water tank connected to the hydraulic module. The start and stop of air conditioning and heating and domestic hot water are controlled by the outlet water temperature of the hydraulic module and the water tank temperature respectively.
  • Page 9 Scenario 5: Space heating and domestic hot water + return water function A return water function is provided for the domestic hot water. The start and stop of the return water pump are controlled by the return water temperature, so there is no waiting for the use of hot water. The main board has return water pump and return water temperature sensor interfaces, which are started by dialing on the main board (the return water pump and the mixing water pump share an interface, the mixing water pump is defaulted in the system).
  • Page 10 Scenario 6: Only used for space heating (suitable for multiple terminals, water temperature adjustment) During heating, the user can connect multiple terminals simultaneously, e.g. floor heating system and heating radiators (or fan coils). However, as the water temperature required for the heating radiator is higher than that required for the floor heating, a mixing water valve and a mixing water pump are provided for the floor heating to adjust the water temperature of the floor heating.
  • Page 11 Scenario 7: Space heating (with auxiliary heating source) and domestic hot water 1. EA heater for pipeline: A pipeline electric heater is installed on the space heating mains, with its start and stop controlled by the main temperature senor, and the main board has reserved auxiliary heating source and heating water main temperature sensor interfaces.
  • Page 12 Scenario 8: Space heating (with auxiliary heating source) and domestic hot water 2. Other auxiliary heating sources: An auxiliary heating source is installed on the space heating mains, with its start and stop controlled by the main temperature senor, and the main board has reserved auxiliary heating source and heating water main temperature sensor interfaces.
  • Page 13 Scenario 9: External signal interface The hydraulic module has a reserved external on/off signal interface. When it is on, the hydraulic module will operate according to the wired controller setting; when it is off, the hydraulic module will shut down. 1 Outdoor unit 6 wired controller 2 Hydraulic module...
