After powering on, the system begins with running the cooling / hot water mode to produce free hot water. If the cold water of the air conditioner is observed to reach the pre-set value, but the domestic hot water does not match up to its set temperature, the system will switch to a single hot water mode. Similarly, when the temperature of the domestic hot water matches its set value, but the cold water of the air conditioner has not yet attained the status its requires, the unit will transition to a single-system cold water mode. If both the air conditioner cold water and the domestic hot water reach their set temperatures, the compressor will stop and enter standby mode.
Winter Heating Hot Water Mode 1 (with priority on hot water): Upon start-up, the unit engages immediately and begins generating hot water. Once the temperature reaches the pre-set value, the unit will switch itself to the heating mode for additional warmth. Once the hot water drops beneath the designated temperature, the unit will then switch back to producing hot water until both the air conditioning and the hot water reach their individual set points, and the compressor shuts off, entering standby mode.
Winter Heating Hot Water Mode 1 (with priority on heating): Upon start-up, this mode of winter heating will firstly engage single heating mode. Once the temperature is reached, the unit will automatically switch to hot water mode. When the temperature falls below the set level again, it will seamlessly transition to heating mode. Once the hot water and air conditioning have both passed the predetermined benchmark, the compressor will stop running and enter a standby state.
This hot water mode is designed to function with ease; once the hot water reaches the desired temperature, the compressor stops and moves into standby mode. The unit itself will automatically kick back in as soon as the water temperature starts to fall below the pre-set level and begin working to generate more hot water.
This unit only runs on a heating mode - when the temperature rises to the desired threshold, the compressor will shut off, switching to standby mode. Should the temperature dip below the threshold again, the unit will automatically restart, heating back up.
This unit only operates on the cooling mode; as soon as it reaches the desired temperature, the compressor shuts off and goes into a standby. But if the temperature rises above the preset level, the unit will start up again and keep it at the predefined coolness. In the summer, when you don't need hot water, the refrigeration mode is a great option as it prevents the unit from constantly turning on and off.
