EHBH04+08 + ERLQ004~008Daikin Altherma - Low Temperature Split4P313774-1 – 2012.05Installer reference guide105 Application guidelinesConfigurationBenefitsQ 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.SetupQ The heat pump convectors are directly connected to the indoorunit.Q A shut-off valve (field supply) is installed before the under floorheating to prevent condensation on the floor during coolingoperation.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 by one digital output (X2M/33and X2M/34) on the indoor unit to:Q The heat pump convectorsQ The shut-off valveSetting 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.A 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.BAaSetting 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.
