Indoor unit for air to water heat pump system
4PW62576-1 – 10.2010
Installation manual
23
Connect the terminals on top of the front part of the digital
controller and the terminals inside the unit (P1 to 16, P2 to 16a).
4 Reattach the upper part of the digital controller.
First begin fitting from the clips at the
bottom.
8. START-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.
8.1. DIP switch settings overview
DIP switch SS2 is located on the switch box PCB (see "5.3. Switch
box main components" on page 11) and allows configuration of
domestic hot water tank installation, room thermostat connection and
pump operation.
8.2. Room thermostat installation configuration
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):
• space heating or cooling on/off (y)
• heating/cooling changeover (=)
• heating and cooling schedule timers (pr)
NOTICE
■ When wiring, run the wiring away from the power
supply wiring in order to avoid receiving electric
noise (external noise).
■ Peel the shield for the part that
has to pass through the inside of
the digital controller case ( l ).
CAUTION
Be careful not to pinch the wiring when attaching.
CAUTION
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
See "2. General safety precautions" on page 2.
WARNING
Switch off the power supply before opening the switch box
service panel and making any changes to the DIP switch
settings.

operation mode of the
heat pump when there is a
simultaneous demand for
more space heating/
cooling and domestic
water heating.
(a) Only applicable in case DIP switch 2 = ON.

Priority to highest
demand side
(b)
(b) Heating/cooling or domestic water heating mode can be restricted by schedule
timer and/or field settings (4, 5, 8).
■ 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.
INFORMATION
■ 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.
