2.4 Placing the temperature sensors2.4.1 Placing the temperature sensorsIt is important that the sensors are mounted in the correct positionin your system.The temperature sensor mentioned below are sensors used for theECL Comfort 210 / 296 / 310 series which not all will be neededfor your application!Outdoor temperature sensor (ESMT)Theoutdoorsensorshouldbemountedonthatsideofthebuildingwhere it is less likely to be exposed to direct sunshine. It should notbe placed close to doors, windows or air outlets.Flow temperature sensor (ESMU, ESM-11 or ESMC)Place the sensor max. 15 cm from the mixing point. In systemswith heat exchanger, Danfoss recommends that the ESMU-type tobe inserted into the exchanger flow outlet.Make sure that the surface of the pipe is clean and even wherethe sensor is mounted.Return temperature sensor (ESMU, ESM-11 or ESMC)The return temperature sensor should always be placed so that itmeasures a representative return temperature.Room temperature sensor(ESM-10, ECA 30 / 31 Remote Control Unit)Place the room sensor in the room where the temperature is to becontrolled. Do not place it on outside walls or close to radiators,windows or doors.Boiler temperature sensor (ESMU, ESM-11 or ESMC)Place the sensor according to the boiler manufacturer’sspecification.Air duct temperature sensor (ESMB-12 or ESMU types)Place the sensor so that it measures a representative temperature.DHW temperature sensor (ESMU or ESMB-12)PlacetheDHWtemperaturesensoraccordingtothemanufacturer’sspecification.Slab temperature sensor (ESMB-12)Place the sensor in a protection tube in the slab.ESM-11: Do not move the sensor after it has been fastened in order toavoid damage to the sensor element.ESM-11, ESMC and ESMB-12: Use heat conducting paste for quickmeasurement of the temperature.ESMU and ESMB-12: Using a sensor pocket to protect the sensor will,however, result in a slower temperature measurement.VI.GU.F6.02 © Danfoss | 2017.10 | 21Operating Guide ECL Comfort 310, application A377
