LZT/SW6 REFRIGERANT CIRCUIT LAYOUT
The LZT/SW6 version is suitable to produce cold water, hot water for heating and domestic use. The unit is supplied with an
additional heat exchanger used as condenser for the domestic hot water that, is produced independently from the operation mode of
the unit. The activation of the additional heat exchanger is done automatically by the microprocessor control when the domestic hot
water temperature measured by the sensor is lower than the required set point.

The LZT/SW6 unit, allows the production of cold and hot water, independently from the operation mode of
the unit (heating or cooling).
During winter operation, if domestic hot water is required, it is temporarily stopped the water flow into the
heating system. During summer operation the domestic hot water can be produced at the same time of
the cold water flow.
Domestic hot water is available even when the cooling system is in stand-by or the set point has been
reached.
The unit microprocessor gives always priority to the domestic hot water.
