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

8.2. Room thermostat installation configuration
■
When no room thermostat is connected to
the indoor unit, toggle switch SS2-3 should be
set to OFF.
■
When the room thermostat is connected to
the indoor unit, toggle switch SS2-3 should be
set to ON.
■
On the room thermostat, confirm the correct settings (6®02=yes,
6®05=9, 6®06=5) to prevent the pump from repeatedly turning on
and off (i.e. chattering), and thereby impacting the lifetime of
the pump.

When the room thermostat is connected to the indoor
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 the room thermostat is connected to the indoor
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.
The following table summarizes the required configuration and
thermostat wiring at the terminal block (X2M: 1, 2, 3, 4) 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):

(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.

Without room thermostat: DIP switch SS2-3=OFF
When no thermostat is connected to the indoor 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 DIP switch: SS2-3=ON
When the thermostat is connected to the indoor 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.
