Domestic Hot Water Control: Advanced - Daikin Altherma EDLQ011-016CW1 Installer's Reference Manual

▪ When the leaving water temperature home page is ON and the
operation mode is "heating", then the unit will supply leaving water
to the heat emitters to heat up the room according to normal logic.
▪ When the leaving water temperature home page is ON and the
operation mode is "cooling", then there is no protection.
Shut-off valve
The shut-off valve is in the main leaving water temperature zone,
and is connected to the heating/cooling output.
NOTICE
The output of the shut‑off valve is NOT configurable. Do
NOT change the value of setting [F‑0B]. Only connect NO
(normal open) shut‑off valves.
Operation range
Depending on the average outdoor temperature, the operation of the
unit in space heating or space cooling is prohibited.
Space heating OFF temp: When the averaged outdoor temperature
rises above this value, space heating is turned OFF to avoid
overheating.
# Code
[A.3.3.1] [4-02] 14°C~35°C (default: 35°C)
The same setting is also used in
automatic heating/cooling changeover.
Space cooling On temp:
EBLQ011+014+016CAV3 and EBLQ011+014+016CAW1. When the
averaged outdoor temperature drops below this value, space cooling
is turned OFF.
# Code
[A.3.3.2] [F-01] 10°C~35°C (default: 20°C)
The same setting is also used in
automatic heating/cooling changeover.
Automatic heating/cooling changeover
ONLY applicable for
EBLQ011+014+016CAW1. The end-user sets the desired operation
mode on the user interface: Heating, Cooling or Automatic (see also
operation manual/user reference guide). When Automatic is
selected, the changing of the operation mode is based on:
▪ Monthly allowance for heating and/or cooling: the end-user
indicates on a monthly base which operation is allowed ([7.5]: both
heating/cooling or heating ONLY or cooling ONLY). If the allowed
operation mode changes to cooling ONLY, the operation mode
changes to cooling. If the allowed operation mode changes to
heating ONLY, the operation mode changes to heating.
▪ Averaged outdoor temperature: the operation mode will be
changed in order to ALWAYS be within range determined by the
space heating OFF temperature for heating and the space cooling
On temperature for cooling. If the outdoor temperature drops, the
operation mode switches to heating and vice versa. Note that the
outdoor temperature will
"8 Configuration" on page 50).
When the outdoor temperature is between the space cooling On and
the space heating OFF temperature, the operation mode remains
unchanged unless the system is configured in room thermostat
control with one leaving water temperature zone and quick heat
emitters. In that case, the operation mode will change based on:
▪ Measured indoor temperature: besides the heating and the
cooling desired room temperature, the installer sets a hysteresis
value (e.g. when in heating, this value is related to the desired
cooling temperature) and an offset value (e.g. when in heating,
this value is related to the desired heating temperature). Example:
the desired room temperature in heating is 22°C and in cooling
24°C, with a hysteresis value of 1°C and an offset of 4°C.
Changeover from heating to cooling will occur when the room

temperature rises above the maximum of the desired cooling
temperature added by the hysteresis value (thus 25°C) and the
desired heating temperature added by the offset value (thus
26°C). Oppositely, changeover from cooling to heating will occur
when the room temperature drops below the minimum of the
desired heating temperature subtracted by the hysteresis value
(thus 21°C) and the desired cooling temperature subtracted by the
offset value (thus 20°C).

Domestic hot water control: advanced

Preset tank temperatures
Only applicable when domestic hot water preparation is scheduled
or scheduled + reheat.
You can define preset tank temperatures:
▪ storage economic
▪ storage comfort
▪ reheat
▪ reheat hysteresis
Preset values make it easy to use the same value in the schedule. If
you later want to change the value, you only have to do it in 1 place
(see also operation manual and/or user reference guide).
Storage comfort
When programming the schedule, you can make use of the tank
temperatures set as preset values. The tank will then heat up until
these setpoint temperatures have been reached. Additionally, a
8 Configuration
Description
Space heating OFF temp. If the outdoor
temperature rises above this value, the
operation mode will change to cooling:
Range: 14°C~35°C (default: 35°C)
Space cooling On temp. If the outdoor
temperature drops below this value, the
operation mode will change to heating:
Range: 10°C~35°C (default: 20°C)
Hysteresis: Ensures that changeover is
ONLY done when necessary. Example:
The space operation mode ONLY
changes from cooling to heating when
the room temperature drops below the
desired heating temperature subtracted
by the hysteresis.
Range: 1°C~10°C, step 0.5°C (default:
1°C)
Offset: Ensures that the active desired
room temperature can be reached.
Example: if heating to cooling
changeover would occur below the
desired room temperature in heating, this
desired room temperature could never
be reached.
Range: 1°C~10°C, step 0.5°C (default:
3°C)
