89 Choose from the Daikin "Three Pluses" the functionality that best fits your customer’s needs. The indoor units come in 3 possible versions: heating only, reversible and bizone, giving you the opportunity to tailor your Daikin heating system. Reversible model If cooling is needed, all three indoor units have dedicated reversible models. Reversible means that the system can invert its way of working and provide cooling instead of heating. The cooling function requires a underfloor piping system or fan coil units. Bizone model Only the DHW stainless steel tank model has a dedicated bizone model: you can choose two independent zones with different emitters that need a different temperature level in different rooms (for example: underfloor heating system in the living room and radiators in the bedrooms upstairs).

Daikin Altherma HPC (heat pump convectors) are hydronic emitters that can provide cooling or heating. They can be combined and are a perfect fit with underfloor systems. Your underfloor piping system is designed to receive midtemperature water to heat your home, but when the summer comes, the pipes can also receive colder water to refresh your environment.

In others, cooling can be disabled via installer settings.
