EHBH/X16Daikin Altherma - Low Temperature Split4P313776-1 – 2012.05Installer reference guide85 Application guidelinesQ To deviate from your daily needs, you can temporarilyoverrule the preset values and schedules, use the holidaymode…Under floor heating or radiators – Wireless roomthermostatSetupQ The under floor heating or radiators are directly connected to theindoor unit.Q The room temperature is controlled by the wireless externalroom thermostat (optional equipment EKRTR1).ConfigurationBenefitsQ Wireless. The Daikin external room thermostat is available in awireless version.Q Efficiency. Although the external room thermostat only sendsON/OFF signals, it is specifically designed for the heat pumpsystem.Q Comfort. In case of under floor heating, the wireless externalroom thermostat prevents condensation on the floor duringcooling operation by measuring the room humidity.Heat pump convectorsSetupQ The heat pump convectors are directly connected to the indoorunit.Q The desired room temperature is set via the remote controller ofthe heat pump convectors.Q The space heating/cooling demand signal is sent to one digitalinput on the indoor unit (X2M/1 and X2M/4).Q The space operation mode is sent to the heat pump convectorsby one digital output on the indoor unit (X2M/33 and X2M/34).ConfigurationBenefitsQ Cooling. The heat pump convector offers, besides heatingcapacity, also excellent cooling capacity.Q Efficiency. Optimal energy efficiency because of the interlinkfunction.Q Stylish.Combination: Under floor heating + Heat pumpconvectorsQ Space heating is provided by:Q The under floor heatingQ The heat pump convectorsQ Space cooling is provided by the heat pump convectors only.The under floor heating is shut off by the shut-off valve.A Main leaving water temperature zoneB One single rooma Receiver for wireless external room thermostatb Wireless external room thermostatSetting ValueUnit temperature control:Q #: [A.2.1.7]Q Code: [C-07]1 (Ext RT control): Unit operationis decided by the externalthermostat.Number of water temperaturezones:Q #: [A.2.1.8]Q Code: [7-02]0 (1 LWT zone): MainExternal room thermostat for themain zone:Q #: [A.2.2.4]Q Code: [C-05]Configure according to the setup:Q 1 (Thermo ON/OFF): Whenthe used external roomthermostat or heat pumpconvector can only send athermo ON/OFF condition.No separation betweenheating or cooling demand.Q 2 (C/H request): When theused external roomthermostat can send aseparate heating/coolingthermo ON/OFF condition.BAbaA Main leaving water temperature zoneB One single rooma Remote controller of the heat pump convectorsINFORMATIONWhen using multiple heat pump convectors, make sureeach one receives the infrared signal from the remotecontroller of the heat pump convectors.Setting ValueUnit temperature control:Q #: [A.2.1.7]Q Code: [C-07]1 (Ext RT control): Unit operationis decided by the externalthermostat.Number of water temperaturezones:Q #: [A.2.1.8]Q Code: [7-02]0 (1 LWT zone): MainExternal room thermostat for themain zone:Q #: [A.2.2.4]Q Code: [C-05]1 (Thermo ON/OFF): When theused external room thermostat orheat pump convector can onlysend a thermo ON/OFFcondition.
