EKHBRD011~Y1

Indoor unit for air to water heat pump system and options

4PW60971-1

Other operation modes

Start up operation (

d

)

During start up, the 

d

  icon displays, indicating that the heat

pump is starting up and is not working in a steady state condition.

Defrost operation (

d

)

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. It reverses the cycle and takes heat from the indoor
system to prevent freezing of the outdoor system. After a maximum
of 12 minutes of defrost operation, the system returns to space
heating operation.

Quiet mode operation (

s

)

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 

s

 button to activate quiet mode operation.

The 

s

 icon displays.

If the controller is set to permission level 2 or 3 (refer to "Field
settings" in the installation manual), the 

s

  button is not

operable.

2

Press the 

s

 button again to deactivate quiet mode operation.

The 

s

 icon disappears.

There are 3 different levels of quiet mode operation. The desired
quiet mode is set through a

eld setting. Refer to the chapter "Field

settings" on page 15 for a detailed description how to set one or more

fi

eld settings.

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.
