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 9) and allows configuration of
domestic hot water tank installation, room thermostat connection and
pump operation.
Switch off the power supply before opening the switch box
service panel and making any changes to the DIP switch
settings.

domestic water heating.

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 and change over
operation.

(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.

NOTE
To set the pump speed, refer to "Setting the pump
speed" on page 20.
Without room thermostat
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
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.
With room thermostat
When a thermostat is connected to the unit, the pump will operate
continuously whenever there is heating or cooling demand requested
by the thermostat.
