5.2 Setting up the space heating
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 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 requirements are clear, Daikin recommends
to follow the setup guidelines below.
NOTICE
If an external room thermostat is used, the external room
thermostat will control the room frost protection. However,
the room frost protection is only possible if the leaving
water temperature control on the unit's user interface is
turned ON.
INFORMATION
In case an external room thermostat is used and room frost
protection needs to be guaranteed in all conditions, then
you have to set Emergency [9.5] to Automatic.

A Main leaving water temperature zone
B One single room
a User interface used as room thermostat
▪ The room temperature of the main room is controlled by the user
interface used as a room thermostat (optional equipment
EKRUDAS).
Configuration
Setting Value
Unit temperature control:
▪ #: [2.9]
▪ Code: [C-07]
2 (Room thermostat): Unit
operation is decided based on
the ambient temperature of the
user interface.
Number of water temperature
zones:
▪ #: [4.4]
▪ Code: [7-02]
0 (Single zone): Main
Benefits
▪ 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…c

Benefits
▪ Wireless. The Daikin external room thermostat is available in a
wireless version.
▪ Efficiency. Although the external room thermostat only sends ON/
OFF signals, it is specifically designed for the heat pump system.
