Installer reference guide7 EHBH/X16Daikin Altherma - Low Temperature Split4P313776-1 – 2012.055 Application guidelines4.2.3 Possible combinations of indoor unit and domestic hot water tank5 Application guidelines5.1 Overview: Application guidelinesThe purpose of the application guidelines is to give a glance of thepossibilities of the Daikin heat pump system.This chapter contains applications guidelines for:Q Setting up the space heating/cooling systemQ Setting up an auxiliary heat source for space heatingQ Setting up the domestic hot water tankQ Setting up the energy meteringQ Setting up the power consumptionQ Setting up an external temperature sensor5.2 Setting up the space heating/cooling systemThe Daikin heat pump system supplies leaving water to heat emittersin one or more rooms.Because the system offers a wide flexibility to control the temperaturein each room, you need to answer the following questions first:Q How many rooms are heated (or cooled) by the Daikinheat pump system?Q Which heat emitter types are used in each room and what istheir design leaving water temperature?Once the space heating/cooling requirements are clear, Daikinrecommends to follow the setup guidelines below.5.2.1 Single roomUnder floor heating or radiators – Wired roomthermostatSetupQ The under floor heating or radiators are directly connected to theindoor unit.Q The room temperature is controlled by the user interface, whichis used as room thermostat. Possible installations:Q User interface (standard equipment) installed in the roomand used as room thermostatQ User interface (standard equipment) installed at the indoorunit and used for control close to the indoor unit + userinterface (optional equipment EKRUCAL) installed in theroom and used as room thermostatConfigurationBenefitsQ Cost effective. You do NOT need an additional external roomthermostat.Q Highest comfort and efficiency. The smart room thermostatfunctionality can decrease or increase the desired leaving watertemperature based on the actual room temperature(modulation). This results in:Q Stable room temperature matching the desired temperature(higher comfort)Q Less ON/OFF cycles (more quiet, higher comfort andhigher efficiency)Q Lowest possible leaving water temperature (higherefficiency)Q Easy. You can easily set the desired room temperature via theuser interface:Q For your daily needs, you can use preset values andschedules.Indoor unitDomestic hot water tankEKHWS EKHWSU EKHWE EKHWETEHBH16CA3V O O O OEHBX16CA3V O O O OEHBH16CA9W O O O OEHBX16CA9W O O O ONOTICEQ The illustrations in the application guidelines aremeant for reference only, and are NOT to be used asdetailed hydraulic diagrams.
