Setting Up The Space Heating/Cooling System; Single Room - Daikin ERLQ004~008CAV3 Reference Manual

▪ 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
B
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

5 Application guidelines
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...

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.
