Daikin Altherma – Low temperature split
4P449978-1B – 2018.07
▪ A bypass valve must be installed to make water recirculation
possible when all shut-off valves are closed. To guarantee reliable
operation, provide a minimum water flow as described in table "To
check the water volume and flow rate" in
"6.4 Preparing water
piping" on page 25 .
▪ The user interface connected to the indoor unit decides the space
operation mode. Mind that the operation mode on each room
thermostat must be set to match the indoor unit.
▪ The room thermostats are connected to the shut-off valves, but do
NOT have to be connected to the indoor unit. The indoor unit will
supply leaving water all the time, with the possibility to program a
leaving water schedule.
Configuration
Setting Value
Unit temperature control:
▪ #: [A.2.1.7]
▪ Code: [C-07]
0 (LWT control): Unit operation is
decided based on the leaving
water temperature.
Number of water temperature
zones:
▪ #: [A.2.1.8]
▪ Code: [7-02]
0 (1 LWT zone): Main
Benefits
Compared with under floor heating or radiators for one room:
▪ Comfort. You can set the desired room temperature, including
schedules, for each room via the room thermostats.

▪ The desired room temperature is set via the remote controller of
the heat pump convectors.
▪ The user interface connected to the indoor unit decides the space
operation mode.
▪ The heating demand signals of each heat pump convector are
connected in parallel to the digital input on the indoor unit (X2M/1
and X2M/4). The indoor unit will only supply leaving water
temperature when there is an actual demand.
INFORMATION
To increase comfort and performance, Daikin recommends
to install the valve kit option EKVKHPC on each heat pump
convector.

▪ For each room with heat pump convectors: The heat pump
convectors are directly connected to the indoor unit.
▪ For each room with under floor heating: A shut-off valve (field
supply) is installed before the under floor heating. It prevents hot
water supply when the room has no heating demand.
▪ For each room with heat pump convectors: The desired room
temperature is set via the remote controller of the heat pump
convectors.
▪ For each room with under floor heating: The desired room
temperature is set via the external room thermostat (wired or
wireless).
▪ The user interface connected to the indoor unit decides the space
operation mode. Mind that the operation mode on each external
room thermostat and remote controller of the heat pump
convectors must be set to match the indoor unit.
