Controller for temperature control - EKC 201 and EKC 301
The controller is a simple thermostat regulator in which some refrigeration-technical functions have been integrated so that it can replace a link-up of a group of thermostats and timers. The controller has been specially designed for refrigeration applications, but may of course also be used for other forms of regulation where this is expedient.
Application
The controller is a simple thermostat regulator in which some refrigeration-technical functions have been integrated so that it can replace a link-up of a group of thermostats and timers. The controller has been specially designed for refrigeration applications, but may of course also be used for other forms of regulation where this is expedient.
The controller comes in several versions with a growing number of functions - from the simple one with just one relay to more advanced versions with three relays. All versions are furthermore available with an alarm function. The number of relays will then be increased by one.
The relays are used for controlling: - compressor
* fan
* defrost
* alarm
One of the connections to the controller is a digital input. This input will register the position of a connected switch and depending on the functions you want to use, it will work, as follows:
* activate a door alarm if the door remains open for longer than allowed
* start a defrost
* or transmit the signal to the data communication
Advantages
* One electronic controller is able to replace several tradi-tional controllers and defrost clocks
* Can be supplied for panel as well as DIN-rail mounting
* Temperatures, times, operating conditions, parameter codes and alarm and fault codes can be
read from the display
* Three LEDs indicate the actual condition of the system:
* refrigeration
* defrost
* fan running
* Easy to re-establish factory setting
* In the event of error function, the actual parameter code can be displayed
* All alarms are indicated bya the three LEDs fashing at once
* Easy to install data communication at a later date
