Energy saving tips
▪ If the DHW consumption differs from day to day, you can program
a weekly schedule with different desired DHW tank temperatures
for each day.
▪ The lower the desired DHW tank temperature, the more cost
effective. By selecting a larger DHW tank, you can lower the
desired DHW tank temperature.
▪ The heat pump itself can produce domestic hot water of maximum
55°C (50°C if outdoor temperature is low). The electrical
resistance integrated in the heat pump can increase this
temperature. However, this consumes more energy. Daikin
recommends to set the desired DHW tank temperature below
55°C to avoid using the electrical resistance.
▪ The higher the outdoor temperature, the better the performance of
the heat pump.
▪ If energy prices are the same during the day and the night,
Daikin recommends to heat up the DHW tank during the day.
▪ If energy prices are lower during the night, Daikin recommends
to heat up the DHW tank during the night.
▪ When the heat pump produces domestic hot water, it cannot heat
up a space. In case you need domestic hot water and space
heating at the same, Daikin recommends to produce the domestic
hot water during the night when there is lower space heating
demand.
5.4.3 Setup and configuration – DHW tank
▪ For large DHW consumptions, you can heat up the DHW tank
several times during the day.
▪ To heat up the DHW tank to the desired DHW tank temperature,
you can use the following energy sources:
▪ Thermodynamic cycle of the heat pump
▪ Electrical booster heater
▪ For more information about:
▪ Optimizing the energy consumption for producing domestic hot
water, see "8 Configuration" on
▪ Connecting the electrical wiring of the domestic hot water tank
to control box EKCB07CAV3, see the installation manual of the
domestic hot water tank.
▪ Connecting the water piping of the domestic hot water tank to
the outdoor unit, see the installation manual of the domestic hot
water tank.

▪ The DHW pump is field-supplied and its installation is the
responsibility of the installer.
▪ The temperature of the DHW tank can be set to a maximum of
75°C (if [E-07]=0) or 80°C (if [E-07]=5). If the applicable legislation
requires a higher temperature for disinfection, you can connect a
DHW pump and heater element as shown above.
▪ If applicable legislation requires disinfection of the water piping
until the tapping point, you can connect a DHW pump and heater
element (if needed) as shown above.
▪ For more information about the recirculation connection, see
"7.8.8 To connect the domestic hot water pump" on
the installation manual of the domestic hot water tank.
Configuration
The outdoor unit can control DHW pump operation. For more
information, see "8 Configuration" on
