NOTICE
▪ Make sure the auxiliary boiler and its integration in the
system complies with applicable legislation.
▪ Daikin is NOT responsible for incorrect or unsafe
situations in the auxiliary boiler system.
▪ Make sure the return water to the heat pump does NOT exceed
55°C. To do so:
▪ Set the desired water temperature via the auxiliary boiler
controller to maximum 55°C.
▪ Install an aquastat valve in the return water flow of the
heat pump.
▪ Set the aquastat valve to close above 55°C and to open below
55°C.
▪ Install non-return valves.
▪ Make sure to only have one expansion vessel in the water circuit.
An expansion vessel is already pre-mounted in the outdoor unit.
▪ Install control box EKCB07CAV3 and option box EK2CB07CAV3.
▪ Connect X8M/3 and X8M/4 (changeover to external heat source)
on option box EK2CB07CAV3 to the auxiliary boiler thermostat.
▪ To setup the heat emitters, see
cooling system" on page 12.
Configuration
Via the user interface (quick wizard):
▪ Set the use of a bivalent system as external heat source.
▪ Set the bivalent temperature and hysteresis.

NOTICE
▪ Make sure the bivalent hysteresis has enough
differential to prevent frequent changeover between
outdoor unit and auxiliary boiler.
▪ Because the outdoor temperature is measured by the
outdoor unit air thermistor, install the outdoor unit in the
shadow so that it is NOT influenced or turned ON/OFF
by direct sunlight.
▪ Frequent changeover may cause corrosion of the
auxiliary boiler. Contact the manufacturer of the
auxiliary boiler for more information.
Changeover to external heat source decided by an auxiliary
contact
▪ Only possible in external room thermostat control AND one
leaving water temperature zone (see
heating/cooling system" on page 12).
▪ The auxiliary contact can be:
▪ An outdoor temperature thermostat
▪ An electricity tariff contact
▪ A manually operated contact
▪ ...

NOTICE
▪ Make sure the auxiliary contact has enough differential
or time delay to prevent frequent changeover between
outdoor unit and auxiliary boiler.
▪ If the auxiliary contact is an outdoor temperature
thermostat, install the thermostat in the shadow so that
it is NOT influenced or turned ON/OFF by direct
sunlight.
▪ Frequent changeover may cause corrosion of the
auxiliary boiler. Contact the manufacturer of the
auxiliary boiler for more information.
