Danfoss EKC Temperature Controller EKC 202 controllers can be used for a wide range of different refrigeration applications – from control of air temperatures and defrost to more advanced applications, including control of light and fans. Compact hardware design: Integration of 230 V a.c. voltage supply, four relays and built-in ”super cap” real time clock without compromising with the dimensions. A selection of supplementary modules makes it possible to extend the functionality with e.g. RS 485 network card and battery back-up. The controller contains a temperature control where the signal can be received from one or two temperature sensors. The thermostat sensors are either placed in the cold air flow after the evaporator, in the warm air flow just before the evaporator, or both. A setting will determine how great an influence the two signals are to have on the control. A measurement of the defrost temperature can be obtained directly through the use of an S5 sensor or indirectly through the use of the S4 measurement. Four relays will cut the required functions in and out – the application determines which. The options are the following: • Refrigeration (compressor or relay) • Fan • Defrost • Rail heat • Alarm • Light Features:
Several applications in the same unit
The controller has integrated refrigeration-technical functions, so that it can replace a whole collection of thermostats and timers
