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

12.1. DIP switch settings overview

DIP switch SS2 is located on the control box PCB (refer to the
chapter "Indoor unit switch box" in the EBHQ outdoor installation
manual) and allows configuration of domestic hot water tank
installation, room thermostat connection and pump operation.
WARNING
Switch off the power supply before opening the control box
service panel and making any changes to the DIP switch
settings.

12.2. 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.
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.
The following table summarizes the required configuration and
thermostat wiring at the terminal block (X2M: 1, 2, 3, 4) in the control
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.
