Product information for the outdoor unit

Temperature control and inverter

The outdoor unit inverter drives the compressor. Outdoor fan motor and indoor fan motor at the right speed to provide enough capacity to meet the heat load of all indoor units in operation.

When the temperature in the zones approaches the setpoint demand. The inverter will slow everything down. This is normal operation.

B. temperature setpoint is reached. The inverter will run everything slowly to provide small amounts of capacity to keep rooms comfortable. Once in a while. the air leaving the indoor units will be close to or at room temperature. That is normal.

Thanks to this precise coordination of capacity and load, ductless air conditioning systems achieve high levels of efficiency.

Adapting the outdoor unit to indoor units

The allowed combinations of indoor unit capacity and outdoor unit model are shown on the right. The capacitance values can be adjusted to each of the high walls. Cassette. or Slim Duct/Concealed models.

The systems are not designed to be used with just 1 indoor unit. Do not deviate from the available combinations in these tables.

When ports are not used. Always connect the refrigerant piping to circuits located at the lowest possible connection of the outdoor units. Use pipe reducers to transition from the outdoor unit port size to the required indoor unit port size.
