30 QUIET MODE BUTTON s
This button enables or disables quiet mode.
2.3. Setting up the controller
After initial installation, the user can set the clock and day of the
week.
The controller is equipped with a schedule timer that enables the user
to schedule operations. Setting the clock and day of the week is
required to be able to use the schedule timer.
2.3.1. Setting the clock
1 Hold down the pr button for 5 seconds.
The clock read-out and the day of week indicator start flashing.
2 Use the pi and pj buttons to adjust the clock.
Each time the pi or pj button is pressed, the time will
increase/decrease by 1 minute. Keeping the pi or pj
button pressed will increase/decrease the time by 10 minutes.
3 Use the bi or bj button to adjust the day of the week.
Each time the bi or bj button is pressed the next or
previous day is displayed.
4 Press the < button once to confirm the current set time and day
of the week.
If no button is pressed for 5 minutes, while the clock and day of
the week read-out are still flashing, the clock and day of the
week will return to their previous setting and the clock setting
function will no longer be active.
2.3.2. Setting the schedule timer
To set the schedule timer, refer to chapter2.6. "Programming and
consulting the schedule timer" on page 5.
2.4. Description of the operation modes
2.4.1. Heating operation (hh
hh
)
In this mode, heating will be activated as required by the temperature
set point. The set point can be set manually (refer to "2.5.1. Manual
operation" on page 3), weather dependent (refer to "2.5.3. Weather
dependent operation (heat pump models only)" on page 4) or
according to the defrost demand from the outdoor unit.
Defrost (dd
dd
)
In heating operation, freezing of the outdoor heat exchanger may
occur due to low outdoor temperature. If this risk occurs, the system
goes into defrost operation. It reverses the cycle and takes heat from
the indoor system to prevent freezing of the outdoor system. After a
maximum of 10 minutes of defrost operation, the system returns to
heating operation.
2.4.2. Cooling operation (cc
cc
)
In this mode, cooling will be activated as required by the temperature
set point.
2.4.3. Quiet mode operation (ss
ss
)
Quiet mode operation means that the outdoor unit works at reduced
capacity so that the noise produced by the outdoor unit drops. This
implies that the indoor heating and cooling capacity will also drop.
Beware of this when a certain level of heating is required indoors.
2.5. Controller operations
2.5.1. Manual operation
In manual operation, the user manually controls the temperature
settings of the installation. The last setting remains active until the
user changes it or until the schedule timer does.
As the controller can be used for a wide variety of installations, it is
possible to select a function which is not available on your
installation. In that case the message n will appear.
NOTE
Buttons that are not described above are not used in
this configuration. Pressing these buttons (w,
wbj and wbi) has no influence on the
operation. When these buttons are pressed,
n will be displayed.
NOTE
The clock needs to be set manually. Adjust the setting
when switching from summertime to wintertime and
vice versa.
NOTE
Defrosting stops:
■ when switching between cooling and heating,
■ at a low outdoor temperature and a low
temperature of the incoming water,
■ when the desired defrost temperature is reached,
i.e. defrost stop temperature (contact your local
Daikin dealer).
Heating operation restarts automatically when the
water temperature is above the defrost stop
temperature.
NOTE
Heating operation is not possible if the installation is a
"cooling only" installation.
NOTE
■ The cooling temperature set point can only be set
manually (refer to "2.5.1. Manual operation" on
page 3).
■ Switching between heating and cooling operation
can only be done by pressing the = button
(provided the unit is not a "cooling only" unit).
