Daikin Altherma - Low Temperature Split
4P313775-1C – 2012.11
▪ 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
Configuration
Setting Value
Unit temperature control:
▪ #: [A.2.1.7]
▪ Code: [C-07]
2 (RT control): Unit operation is
decided based on the ambient
temperature of the user interface.
Number of water temperature
zones:
▪ #: [A.2.1.8]
▪ Code: [7-02]
0 (1 LWT zone): Main
Benefits
▪ Cost effective. You do NOT need an additional external room
thermostat.
▪ Highest comfort and efficiency . The smart room thermostat
functionality can decrease or increase the desired leaving water
temperature based on the actual room temperature (modulation).
This results in:
▪ Stable room temperature matching the desired temperature
(higher comfort)
▪ Less ON/OFF cycles (more quiet, higher comfort and higher
efficiency)
▪ Lowest possible leaving water temperature (higher efficiency)
▪ Easy . You can easily set the desired room temperature via the
user interface:
▪ For your daily needs, you can use preset values and schedules.
▪ To deviate from your daily needs, you can temporarily overrule
the preset values and schedules, use the holiday mode…

b Wireless external room thermostat
▪ The under floor heating or radiators are directly connected to the
indoor unit.
▪ The room temperature is controlled by the wireless external room
thermostat (optional equipment EKRTR1).
Configuration
Setting Value
Unit temperature control:
▪ #: [A.2.1.7]
▪ Code: [C-07]
1 (Ext RT control): Unit operation
is decided by the external
thermostat.
Number of water temperature
zones:
▪ #: [A.2.1.8]
▪ Code: [7-02]
0 (1 LWT zone): Main
External room thermostat for the
main zone:
▪ #: [A.2.2.4]
▪ Code: [C-05]
Configure according to the setup:
▪ 1 (Thermo ON/OFF): When
the used external room
thermostat or heat pump
convector can only send a
thermo ON/OFF condition. No
separation between heating or
cooling demand.
▪ 2 (C/H request): When the
used external room thermostat
can send a separate heating/
cooling
thermo ON/OFF
condition.
