Installation manual3 EKHBRD011~016ADV1+Y1Indoor unit for air to water heat pump system4P402191-1A – 2015.04The remote controller gives immediate feedback to the indoorunit and by doing so it matches in a smart way the unitperformance to the demanded space heating requirements. Inthis way there is no frequent start/stop of the unit or there are notoo big temperature fluctuations in the to be heated rooms. Thisremote controller has also a smart logic functionality whichcontrols the combined space heating and domestic hot waterdemand (e.g. if room temperature drops more than 3°C duringdomestic hot water operation, the unit will automatically switchback to space heating). There is no remote controller near theunit. During service maintenance an additional remote controllercan be connected by a service person. Application 2Space heating and domestic hot water heating with one remotecontroller installed with the unit, and another remote controllerinstalled in the living room.The remote controller gives immediate feedback to the indoorunit and by doing so it matches in a smart way the unitperformance to the demanded space heating requirements.

Thisremote controller has also a smart logic functionality whichcontrols the combined space heating and domestic hot waterdemand (e.g. if room temperature drops more than 3°C duringdomestic hot water operation, the unit will automatically switchback to space heating). The main remote controller (C1) isinstalled in the living room and can access all settings (master).The second remote controller (C2) can not access schedule andfield settings (slave).Refer to the chapter "Electrical wiring work" on page 15 aboutconnecting the master and slave remote controller. Application 3Space heating and domestic hot water heating with a singleremote controller installed with the unit, and the external roomthermostat installed in the living room.There is only a room thermostat on/off control. There is no smartlogic functionality for space heating. When there is simultaneousdemand of space heating and domestic hot water, the domestichot water operation is performed according to the minimum andmaximum timer operation.1 Outdoor unit 10 Collector (field supply)2 Indoor unit 11 Radiator (field supply)3 Refrigerant heatexchanger12 Electronic expansionvalve4 Water heat exchanger 13 By-pass valve (fieldsupply)5 Compressor6 Pump C1 Remote controller(master)7 Shut-off valve8 Motorized 3-way valve(optional)C2 Optional remotecontroller (slave)9 Domestic hot watertank (optional)A Installation placeB Living room10 13C1A BC2743 1212 21865M119Master SlaveOperation ON/OFF Operable OperableDomestic water heating operation ON/OFF Operable OperableSetting the leaving water temperature Operable OperableSetting the room temperature Operable OperableQuiet mode ON/OFF Operable OperableWeather dependent set point operationON/OFFOperable OperableSetting the clock Operable OperableProgramming the schedule timer Operable —Schedule timer operation ON/OFF Operable —Field settings Operable —Error code display Operable OperableTest operation Operable OperableRoom thermostat functionality Operable —Optionally the Daikin room thermostat EKRTR orEKRTW can be connected to the Daikin system.Daikin can not guarantee neither good operation norreliability of the system if another thermostat is used.For those reasons Daikin can not give warranty of thesystem in such case.1 Outdoor unit 10 Collector (field supply)2 Indoor unit 11 Radiator (field supply)3 Refrigerant heatexchanger12 Electronic expansionvalve4 Water heat exchanger 13 By-pass valve (fieldsupply)5 Compressor6 Pump C1 Remote controller7 Shut-off valve T Room thermostat8 Motorized 3-way valve(optional)A Installation placeB Living room9 Domestic hot watertank (optional)C1743 1212 21865M11910 13TA B
