EC3 Recommended Sensor Positions for Cold Room Applications ECN Pxx coil out temperature sensor 1 Position directly after the evaporator on the common suction line as shown below Insure proper thermal contact by using a metallic pipe clamp or temperature resistant plastic straps Do not use standard plastic tie wraps as used for electrical wiring as they may become loose over time which could result in faulty temperature measurements and poor superheat control performance It is recommended to insulate the coil out temperature sensor with ARMAFLEX or equivalent The recommended position of the pipe sensors is between 9 and 3 o clock as shown in the picture EC3_ColdDat cdr PT4 07M suction pressure transmitter 4 Position on the common suction line close to coil out temperature sensor 1 ECN Sxx air temperature sensor 2 Should be mounted on spacers in the middle of the air duct so that there is airflow around and positioned on the inlet of the evaporator as high as possible close to the ceiling ECN Fxx fin temperature sensor 3 Position on the evaporator asymmetric closer to the expansion valve Setup and Parameter Modification Using the Keypad of the ECD 001 For convenience an infrared receiver for the optional IR remote control unit is build in enabling quick and easy modification of the system parameters when a computer interface is not available Alternatively the parameters can be accessed via the 4 button key
