Daikin Altherma – Low temperature split

# Code Description
[A.3.2.1.3] [3-09] Minimum temp (cooling)
15°C~25°C (default: 15°C)
Room temperature step
ONLY applicable in room thermostat control and when the
temperature is displayed in °C.
# Code Description
[A.3.2.4] N/A Room temp. step
▪ 1°C (default). The desired room
temperature on the user interface is
settable per 1°C.
▪ 0.5°C. The desired room temperature
on the user interface is settable per
0.5°C. The actual room temperature is
displayed with an accuracy of 0.1°C.
Room temperature hysteresis
ONLY applicable in case of room thermostat control. The hysteresis
band around the desired room temperature is settable. It is
recommended NOT to change the room temperature hysteresis as it
is set for an optimal use of the system.

# Code Description
N/A [9-0C] 1°C~6°C (default: 1°C)
Room temperature offset
ONLY applicable in case of room thermostat control. You can
calibrate the (external) room temperature sensor. It is possible to
give an offset to the room thermistor value measured by the user
interface or by the external room sensor. The settings can be used
to compensate for situations where the user interface or external
room sensor CANNOT be installed on the ideal installation location
(see installation manual and/or installer reference guide).
# Code Description
Room temp. offset: Offset on the actual room temperature
measured on the user interface sensor.
[A.3.2.2] [2-0A] –5°C~5°C, step 0.5°C (default: 0°C)
Ext. room sensor offset: ONLY applicable if the external room
sensor option is installed and configured (see [C-08])
[A.3.2.3] [2-09] –5°C~5°C, step 0.5°C (default: 0°C)
Room frost protection
ONLY applicable in case of room thermostat control. When the
actual room temperature would drop below the room frost
temperature, the unit will supply leaving water (in heating operation
mode) to the heat emitters to heat up the room again.
NOTICE
Even if the room thermostat control is OFF on the user
interface, room frost protection remains active.
NOTICE
If Emergency is set to Manual ([A.5.1.2]=0), and the unit is
triggered to start emergency operation, the user interface
will ask confirmation before starting. Room frost protection
is active even if the user does NOT confirm emergency
operation.
INFORMATION
If an U4 error occurs, room frost protection is NOT
guaranteed.
INFORMATION
If an U5 error occurs:
▪ when 1 user interface is connected, room frost
protection is NOT guaranteed,
▪ when 2 user interfaces are connected and the second
user interface used for room temperature control is
disconnected (due to miswiring, damage of the cable),
then room frost protection is NOT guaranteed.
# Code Description
N/A [2-06] Room frost protection
▪ 0: disabled (default)
▪ 1: enabled
N/A [2-05] Room antifrost temperature
4°C~16°C (default: 12°C)
Shut-off valve
The following is only applicable in case of 2 leaving water
temperature zones. In case of 1 leaving water temperature zone,
connect the shut-off valve to the heating/cooling output.
The shut-off valve, which is in the main leaving water temperature
zone, output is configurable.
INFORMATION
During defrost operation, the shut-off valve is ALWAYS
opened.
Thermo On/OFF: the valve closes, depending on [F-0B] when there
is no heating demand from the main zone. Enable this setting to:
▪ avoid leaving water supply to the heat emitters in the main LWT
zone (through the mixing valve station) when there is request from
the additional LWT zone.
▪ activate the On/OFF pump of the mixing valve station ONLY when
there is demand. See "5 Application guidelines" on page 11 .
# Code Description
[A.3.1.1.6.1] [F-0B] The shut-off valve:
▪ 0 (No)(default): is NOT influenced by
heating or cooling demand.
▪ 1 (Yes): closes when there is NO
heating or cooling demand.
INFORMATION
The setting [F‑0B] is only valid when there is a thermostat
or external room thermostat request setting (NOT in case
of leaving water temperature setting).
Cooling: ONLY applicable for EHBX and EHVX. The shut-off valve
closes, depending on [F-0C] when the unit is running in cooling
operation mode. Enable this setting to avoid cold leaving water
through the heat emitter and the forming of condensation (e.g. under
floor heating loops or radiators).
