Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material.

Don’t show me this message again. By pressing ‘print’ eanfoss you will print only current page. In other words, you cannot see a status code, if there is an active alarm. Therefore, the control gives the valve the command “open valve” in situations where the reference value is far lower than the actual value. However, there can also be situations in refrigeration plants where humidity is required. This procedure can be avoided by looking at the service menu; here it xanfoss be seen immediately in case of doubt, double check with the thermometer whether the value is realistic.

P control involves standard regulation according to the deviation example: Page 13 If the actual application has a requirement re- fkc max. S according to entered setpoint.

Danfoss reserves the right to alter its products without notice. Of course, it is also the case here that the dew point for dehumidification must always be undershot. Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page If connection sizes larger than 54 mm are required for the suction line, it is recommended that you implement a solution with a main valve.


It is always easy to readjust a system like this through the eliminated condensate quantity at the evaporator.

The controller now compares its temperature set point with the actual value and decides whether the stepper motor valve should be opened further or closed. Digital controller for refrigeration and defrost, 1 relay pages. It is possible to equip the control with a LON module and record the appropriate data using a master unit and to intervene in the control system remotely using a modem connection.

Even with a temperature difference of just 1 K, the control forces a small opening to prevent the control from overshooting the set point. This point can be directly influenced with an electronic suction throttle system: A valve that is almost closed creates a high outlet temperature.

The first option is the fastest possible refrigeration. Page 12 Cut out NTC resistor in actuator. In the case of this setting, a very clear undershooting of the outlet temperature of the evaporator is to be expected to facilitate fast refrigeration and ensure the reference temperature is quickly achieved. The controller can be completely programmed using these two buttons combined with a three-digit display where all important data is displayed.

To print the manual completely, please, download it. This can be easily achieved with electronic suction throttle regulation or media temperature control.

Precise media temperature control. Defrosting The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact.


Different transient processes in the start-up phase Special attention must be paid to the start-up phase of regulation.

The individual status codes have the following meanings: Controller for operation of evaporator on water chiller danfose pages. Controller for control of industrial evaporator 16 pages.

All parameter values that begin with “u” display actual plant values which are important for all types of troubleshooting and for evaluating the state of the plant. A completely open valve ensures maximum refrigeration and therefore the lowest possible outlet temperature in the actual load situation.

The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant. For safety, a maximum defrost duration can also be set in the refrigeration controller, which ends the defrosting process in the case of a defective defrost kec or a similar fault.

The controller is operated using two push buttons. This also applies to products already on order provided that such alternations can be made without subsequential changes being necessary in specifications already agreed.

Here it is important to eliminate even the smallest temperature changes so that the measuring results are not affected. This system does not inlude any inner control loop. The advantage of this is very gentle cooling of unpackaged goods, in which any unnecessary dehumidification is avoided.
