The units can be combined with Daikin fan coil units, floor heating
applications, low temperature radiators, Daikin domestic water
heating applications and solar kit for domestic hot water applications.
Heating/cooling units and heating only units
The unit range consists of two main versions: a heating/cooling

the outdoor unit. The backup heater models are available for a
heating capacity of 6 and 9 kW, and – depending on the heating
capacity – for three different power supply specifications.
