Automatic setback function

Setback function provides the possibility to lower the room
temperature. The setback function can for instance be activated
during the night because the temperature demands during night and
day are not the same.

The setback function is configured through field settings. Refer to

"4.15. Field settings" on page 19

 for a detailed description how to set

one or more field settings.

[2-00] Status: defines whether the setback function is turned ON
(1) or OFF (0)

[2-01] Start time: time at which setback is started

[2-02] Stop time: time at which setback is stopped

[5-02] Leaving water setback temperature (temperature drop)

Emergency operation

[8-02] Emergency operation

During emergency mode, heating is only done by the heater kit,
not by the heat pump.

Activation of emergency mode is done by changing field setting
[8-02]=1.

Activating the emergency mode will stop the heat pump
operation. The pump of the indoor unit will be started, but
heating itself is done by the heater kit. If there are no error
conditions in leaving or returning water thermistors, the heater
kit can start to follow emergency operation.

4.5.

Space cooling operation ( )

Space cooling operation can be controlled in two different ways:

based on room temperature,

based on leaving water temperature.

The purpose of each operation and how the configuration is done, is
explained below.

Room temperature control

In this mode, cooling will be activated as required by the room
temperature set point. The set point can be set manually or through
the schedule timer.

 for setup of the schedule timer function.

3

Use the 

 and 

 buttons to select the leaving

water temperature which you want to be used to cool down your
system (for detailed information see 

"Leaving water temperature

control" on page 6

).

Leaving water temperature control

In this mode, cooling will be activated as required by the water
temperature set point. The set point can be set manually or through
the schedule timer.

Selecting space cooling operation

1

Use the 

 button to switch ON/OFF space cooling ( ).

Icon 

 appears on the display as well as the corresponding

NOTE

When using room temperature control, space cooling
operation based on room temperature will have priority
over leaving water control.

Note that it is possible that the leaving water
temperature becomes lower than the set point if the
unit is controlled by room temperature.

NOTE

When an external room thermostat is installed,
the thermo ON/OFF is determined by the external
room thermostat. The remote controller is than
operated in the leaving control mode and is not
functioning as a room thermostat.

The remote controller ON/OFF status always has
priority over the external room thermostat!

Setback operation and weather dependent
setpoint are not available in cooling operation.
