TART UP AND CONFIGURATION
The unit should be configured by the installer to match the installation
environment (outdoor climate, installed options, etc.) and user
expertise.
It is important that all information in this chapter is read
sequentially by the installer and that the system is
configured as applicable.

DIP switch settings overview

DIP switch SS2 is located on the switch box PCB (see "Switch box
main components (door 2)" on page 13) and allows configuration of
domestic hot water tank installation, room thermostat connection and
pump operation.
WARNING
Switch off the power supply before opening the switch box
service panel and making any changes to the DIP switch
settings.

4 This setting decides the
operation mode when
there is a simultaneous
demand for more space
heating/cooling and
domestic water heating.
(a) only applicable in case DIP switch 2 = ON
(b) Heating/cooling or domestic water heating mode can be restricted by schedule
timer and/or field settings (4, 5, 8).
Room thermostat installation configuration
When no room thermostat is connected to
the unit, toggle switch SS2-3 should be set to
OFF.
When a room thermostat is connected to the
unit, toggle switch SS2-3 should be set to ON.
On the room thermostat, set the hysteresis appropriately to
prevent the pump from repeatedly turning on and off (i.e.
chattering), and thereby impacting the lifetime of the pump.
NOTE When a room thermostat is connected to the unit,
the heating and cooling schedule timers are never
available. Other schedule timers are not affected.
For more information on the schedule timers, refer
to the operation manual.
When a room thermostat is connected to the unit,
and the = button or y button is pressed, the
centralised control indicator e will flash to
indicate that the room thermostat has priority and
controls on/off
operation.

operation and changeover
The following table summarizes the required configuration and
thermostat wiring at the terminal block in the switch box. Pump
operation is listed in the third column. The three last columns indicate
whether the following functionality is available on the user interface
(UI) or handled by the thermostat (T):
• space heating or cooling on/off (y)
• heating/cooling changeover (=)
• heating and cooling schedule timers (pr)

(a) The pump will stop when space heating/cooling is turned off or when the water
reaches the desired water temperature as set on the user interface. With space
heating/cooling turned on, the pump will then run every 5 minutes during 3
minutes to check the water temperature.
Pump operation configuration
NOTE
To set the pump speed, refer to "Setting the pump
speed" on page 25.
Without room thermostat: DIP switch SS2-3=OFF
When no thermostat is connected to the unit, pump operation will be
determined by the leaving water temperature.
To force continuous pump operation when no room thermostat is
4 connected do the following:
- set toggle switch SS2-3 to ON,
- short-circuit the terminal numbers 1-2-4 on the terminal block
in the switch box.
4
With room thermostat: DIP switch SS2-3=ON
When a thermostat is connected to the unit, the pump will operate
continuously whenever there is heating or cooling demand requested
by the thermostat.
Dual set point
When dual set point is enabled, the pump operation will be
determined depending on the status of the DIP switch SS2-3 and set
point selection contacts. Refer to the pump operation configurations
when the thermostat is connected or not as described above.
When dual set point is enabled, the "forced continuous
pump operation" is not possible. When SS2-3 is ON while
SP1 and SP2 are both closed, the pump operation will be
the same operation as "with room thermostat" and the
second set point will be the applicable set point. Refer to
"Dual set point control" on page 30.
