The following information is valid when installing the optional
domestic hot water tank.

Simultaneous operation of compressor, backup heater and booster
heater is NOT possible. Refer to the following warnings mentioned in
the operation manual:

- Emergency backup heater operation always has priority over
compressor or booster heater operation.

- Balance between space heating/cooling demand and
domestic hot water demand.

To optimize the comfort balance between space heating/cooling and
domestic hot water, the schedule timers must be used.

The following shows step-by-step a possible space heating/cooling
and domestic hot water pattern. To ensure domestic hot water
production, the schedule timers must be used to disable space
heating/cooling. When space heating/cooling is disabled the
heatpump will switch automatically to domestic water heating. In this
case it is not required to program the domestic hot water or booster
heater schedule timer.

In this example, the domestic hot water tank will be heated between

2:00

and

4:00

.

If using a room thermostat, domestic water heating by
compressor or by booster heater is
as the room thermostat demands cooling or heating.

In this case de-activate the room thermostat demand by its
schedule timer.

Refer to the manual of the room thermostat for a detailed
explanation how to de-activate space heating/cooling by
schedule timer, or refer to the separate addendum for an
example of the Daikin room thermostat schedule timer
programming.

water heating and booster heater are not stopped,
than this disinfection can not start.
