5 Application guidelines
5.1 Overview: Application guidelines
The purpose of the application guidelines is to give a glance of the
possibilities of the Daikin heat pump system.
NOTICE
▪ The illustrations in the application guidelines are meant
for reference only, and are NOT to be used as detailed
hydraulic diagrams. The detailed hydraulic
dimensioning and balancing are NOT shown, and are
the responsibility of the installer.
▪ For more information about the configuration settings to
optimize heat pump operation, see "8 Configuration" on
page 42.
This chapter contains applications guidelines for:
▪ Setting up the space heating/cooling system
▪ Setting up an auxiliary heat source for space heating
▪ Setting up the domestic hot water tank
▪ Setting up the energy metering
▪ Setting up the power consumption
▪ Setting up an external temperature sensor
5.2 Setting up the space heating/cooling
system
The Daikin heat pump system supplies leaving water to heat
emitters in one or more rooms.
Because the system offers a wide flexibility to control the
temperature in each room, you need to answer the following
questions first:
▪ How many rooms are heated (or cooled) by the Daikin heat pump
system?
▪ Which heat emitter types are used in each room and what is their
design leaving water temperature?
Once the space heating/cooling requirements are clear, Daikin
recommends to follow the setup guidelines below.
5.2.1 Single room
Under floor heating or radiators – Wired room
thermostat
Setup
A Main leaving water temperature zone
B One single room
a User interface used as room thermostat
▪ The under floor heating or radiators are directly connected to the
indoor unit.
▪ The room temperature is controlled by the user interface, which is
used as room thermostat. Possible installations:
▪ User interface (standard equipment) installed in the room and
used as room thermostat
▪ User interface (standard equipment) installed at the indoor unit
and used for control close to the indoor unit + user interface
(optional equipment EKRUCAL) installed in the room and used
as room thermostat
