Backup heater (option)
▪ The under floor heating or radiators are directly connected to the
outdoor unit – or to the backup heater, if there is one.
▪ The room temperature is controlled by the user interface, that is
connected to control box EKCB07CAV3. Possible installations:
▪ Control box EKCB07CAV3 is installed in the room and the user
interface is used as room thermostat.
▪ Control box EKCB07CAV3 is installed indoors, close to the
outdoor unit + user interface installed in the room and used as
room thermostat.
Configuration

Unit temperature control:
▪ #: [A.2.1.7]
▪ Code: [C-07]
Number of water temperature
zones:
▪ #: [A.2.1.8]
▪ Code: [7-02]
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...

5 Application guidelines
▪ The room temperature is controlled by the wireless external room
thermostat (optional equipment EKRTR1).

External room thermostat for the
main zone:
▪ #: [A.2.2.E.5]
▪ Code: [C-05]
Benefits
▪ Wireless. The Daikin external room thermostat is available in a
wireless version.
▪ Efficiency. Although the external room thermostat only sends ON/
OFF signals, it is specifically designed for the heat pump system.
▪ Comfort. In case of under floor heating, the wireless external
room thermostat prevents condensation on the floor during cooling
operation by measuring the room humidity.

Remote controller of the fan coil units
▪ Space cooling or heating is provided by the fan coil units.
▪ The desired room temperature is set via the remote controller of
the fan coil units.
▪ A space heating/cooling demand signal is sent to one digital input
on control box EKCB07CAV3 (X2M/1 and X2M/2) (if this signal is
available on the fan coil units and compatible with the control box).
▪ The space operation mode can be sent to the fan coil units by one
digital output on control box EKCB07CAV3 (X8M/6 and X8M/7) (if
this signal is compatible with the fan coil units).
▪ The main user interface (connected to control box EKCB07CAV3)
decides the space operation mode. Mind that the space operation
mode of the additional user interfaces (used as room thermostat)
must be set to match that of the main user interface.
INFORMATION
When using multiple fan coil units, make sure each one
receives the infrared signal from the remote controller of
the fan coil units.
Value
1 (Ext RT control): Unit operation
is decided by the external
thermostat.
0 (1 LWT zone): Main
1 (Thermo ON/OFF): When the
