Daikin Altherma low temperature monobloc
4P522034-1 – 2018.01
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 main user interface (connected to control box EKCB07CAV3)
decides the space operation mode.
▪ The heating demand signals of each heat pump convector are
connected in parallel to the digital input on control box
EKCB07CAV3 (X2M/1 and X2M/2). The outdoor 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.

e Remote controller of the heatpump convectors
▪ For each room with heat pump convectors: The heat pump
convectors are directly connected to the outdoor unit – or to the
backup heater, if there is one.
▪ For each room with underfloor heating: Two shut-off valves (field
supply) are installed before the underfloor heating:
▪ A shut-off valve to prevent hot water supply when the room has
no heating demand
▪ A shut-off valve to prevent condensation on the floor during
cooling operation of the rooms with heatpump convectors.
▪ 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 main user interface (connected to control box EKCB07CAV3)
decides the space operation mode. Mind that the operation mode
of each external room thermostat and heat pump convector
remote controller must be set to match that of the main user
interface.
