Application 4
Space heating provided through floor heating loops. For floor heating
applications in combination with radiators the water temperature
delivered by the Daikin system is too high. For this reason a
temperature reducing device (field supply) is required to lower the
water temperature (the hot water will be mixed with cold water to
lower the temperature). The control of this field supplied feature is not
done by the heat pump system. The operation and configuration of
the field water circuit is the responsibility of the installer. Daikin only
offers the possibility to have multiple set points on request.
Pattern A
The domestic hot water tank is installed in parallel with the mixing
station(s). This allows operating the unit in space heating and
domestic water heating simultaneously. The balancing of the water
distribution is in this case the responsibility of the installer.
Pattern B
The domestic hot water tank is installed in a separate circuit (with a
3-way valve) of the temperature reducing device(s). This
configuration does not allow simultaneous domestic hot water and
space heating operation.
Refer to the chapter "Multiple set point control" on page 27 for more
information about the configuration of your system.
