4.7. Other operation modes
Start up operation ( )
During start up, the icon displays, indicating that the heat
pump is starting up and is not working in a steady state condition.
Defrost operation ( )
In space heating operation or domestic water 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. During defrost operation, space heating or domestic hot
water operation is not possible.
Quiet mode operation ( )
Quiet mode operation means that the indoor unit works at reduced
compressor speed so that the noise produced by the indoor unit
drops. This implies that it will take longer till the required temperature
set point is reached. Beware of this when a certain level of heating is
required indoors.
Selecting quiet mode operation
1 Use the button to activate quiet mode operation.
The icon displays.
If the controller is set to permission level 2 or 3 (refer to "Field
settings" in the installation manual), the button is not
operable.
2 Press the button again to deactivate quiet mode operation.
The icon disappears.
There are 3 different levels of quiet mode operation. The desired
quiet mode is set through a field setting. Refer to "4.15. Field
settings" on page 19 for a detailed description how to set one or more
field settings.
■ [8-03] Status: defines the level of low noise operation (quiet
mode).
4.8. Simultaneous demand of space heating and
domestic water heating
The unit can not perform domestic water heating and space heating
at the same time. If both modes are requested at the same time, the
unit will heat up till the reheat maximum temperature in 1 time. During
this period, space heating is not possible.
■ If you are using the remote controller room temperature control:
When the reheat temperature is reached, the further heat up of
the domestic hot water tank will be decided by the remote
controller room thermostat in order to prevent the room
temperature to drop too much.
■ If you are using the external room thermostat:
When the reheat temperature is reached, the further heat up of
the domestic hot water tank will be decided by the external room
thermostat thermo conditions and running timers which are
programmed by your installer.
■ If you are using the remote controller leaving water temperature
control:
When the reheat temperature is reached, the further heating up
of the domestic hot water tank will be decided by the running
timers which are programmed by your installer.
4.9. Simultaneous demand of space cooling and
domestic water heating
The unit can perform simultaneous operation of cooling and domestic
water heating.
During cooling operation, the energy taken from the cooled water will
be transferred into energy to heat up the domestic water. It is a
recovery function and is controlled automatically by the system.
This heat recovery is only possible if heat recovery operation is
permitted (it is an installation related setting).
4.10. Temperature read-out mode
On the remote controller, the actual temperatures can be displayed.
1 Push and hold the button for 5 seconds.
The heating/cooling leaving water temperature is displayed
(icons and and are blinking).
2 Use the and buttons to display:
■ The entering water temperature (icons and are
blinking and the icon is flashing slowly).
■ The indoor temperature (icons and are blinking).
■ The outdoor temperature (icons and are blinking).
■ The hot water supply tank temperature (icons and are
blinking).
3 Push the button again to leave this mode. If no button is
pressed, the remote controller leaves the display mode after 10
seconds.

- Actions per day of the week can be programmed totalling 28 actions 12
- Advantage of this method is that you can simply switch off the space heating operation by pushing the button without disabling the automatic domestic hot water storage operation e g during summertime when no space heating is required 12
- By default space heating based on temperature set point method 1 is enabled so only temperature shifts are possible no on off instruction 12
- I 0 03 status defines whether on off instruction can be used in the schedule timer for space heating 12
- In schedule timer operation the installation is controlled by the schedule timer the actions programmed in the schedule timer will be executed automatically 12
- In the following tables both methods on how to interpret the schedule timer are shown 12
- Not displayed by pressing the button 12

- The desired method is set through field setting refer to 4 5 field settings on page 19 for a detailed description how to set one or more field settings 12
- The schedule timer is enabled icon displayed or disabled icon 12
- The space heating schedule timer can be programmed in 2 different ways based on the temperature set point both leaving water temperature and room temperature and based on the on off instruction 12
- When setback function is enabled the setback operation will have priority over the scheduled action in the schedule timer 12
- Actions can be programmed these actions are repeated daily 13
- Advantage of this method is that you can simply switch off the space cooling operation by pushing the button without disabling the automatic domestic hot water storage operation 13
- By default space cooling based on temperature set point method 1 is enabled so only temperature shifts are possible no on off instruction 13
- Domestic water heating 13
- Domestic water heating can be done through several standard operation modes 13
- For cooling no setback function is available 13
- I 0 04 status defines whether on off instruction can be used in the schedule timer for space cooling 13
- I automatic storage by field setting once during night and or once during the afternoon the water is heated till storage set point 13
- I based on the on off instruction 13
- I based on the temperature set point leaving water temperature and room temperature 13
- I for energy saving reasons keep hours with low electricity cost tariffs in mind when programming the schedule timer for domestic water heating 13
- I manual storage if due to special circumstances production of hot water till storage set point is needed immediately 1 time this function can be used 13
- I reheat the reheat function can be activated next to or separate from the automatic storage operation if the user wants to keep the domestic hot water tank at the minimum reheat temperature 13
- I remark that only the time when domestic water heating must start and stop can be programmed in the schedule timer when domestic water heating is enabled the water will be heated till storage set point the storage set point is set through field setting 13
- Next to the standard domestic water heating operation modes it is also possible to freely program the domestic water heating operation through the schedule timer refer to programming domestic water heating on page 16 then the mode is switched on or off at a scheduled time 4 actions can be programmed per mode these actions are repeated daily additional schedule of storage on top of the automatic day and night storage functionality 13

- The space cooling schedule timer can be programmed in 2 different ways 13
- When setback function is enabled the setback operation will have priority over the scheduled action in the schedule timer if on instruction is active if off instruction is active this will have priority over the setback function at any time the off instruction will have the highest priority 13
