It may however also be used as product sensor or condenser sensor. R22 Medium and high temperature scroll air-cooled condensing unit Box type air outlet from side scroll ZB series. R22 Medium and high temperature scroll air-cooled condensing unit Open air outlet from side scroll ZB series.
Here you define which: Digital input Can be used for the following functions: RA Box type air outlet from side Medium and high temperature scroll air-cooled condensing unit scroll ZB series.
Reversed function where the relay cuts out when refrigeration is demanded this wiring produces the result that there will be refrigeration if the supply voltage to the controller fails. OFF-time in minutes Time delay for couplings of two compressors Settings indicate the time that has to elapse from the first relay cuts in and until the next relay has to cut in.
Here are the messages that may appear: Thermostatic Expansion Valves flow direction: The contact will cut in when refrigeration step 2 has to be cut in Defrost. A controller only contains this part of the functions. Notify me about a product availability. The contact will cut in when the controller demands refrigeration Relay 2 Alarm.
Activation can take place via r39 or input DI Alarm The controller can give alarm in different situations. Push briefly 1s the upper button. When the time has expired the function will start a defrost.
When there is an alarm all the light-emitting diodes LED will flash on the controller front panel Alarm delay short alarm delay If one of the two limit values is exceeded, a timer function will commence. Danfss special moulding technique unites the hard front plastic, the softer buttons and the seal, so that they become an integral part of the front panel.
A measurement of the defrost temperature can be obtained directly through the use of an S5 sensor. None, no sensor is adnfoss 1: A pulse signal starts the defrost Refrigeration control with two compressors The two compressors must be of the same size. The possible functions are described in menu o This function can only be used in 1: However the view of —d- will be discontinued if: Defrost During defrost a —d- is shown in the display.
The limit value will also be raised in connection danross reference displacement r Copying to copying key incorrect. Instead of the compressor a solenoid valve may of course be connected in the liquid line. All the mounted sensors must be of the same type. No stress and worry Thanks to the integration with cheap returns you can 012 without stress and be sure that the return process will be hassle free.
HVAC Danfoss Electronic Temperature Controller type Danfoss EKC 102A 084B8500 for Freezer
The display shows the actual room temperature, but by activating the keys the display changes To the set or the actual temperature of the defrost sensor. When the input is open it signals that the door is open.
If the Compressor in operation is unable to lower the temperature to the cutout point, the other compressor will be cut in again. Either with r12 or a DI-input S The compressors used must be of a type that is capable of starting up against a high pressure.
When the compressor is operating it must run for at least x minutes. When copying has started the display returns to o When the compressor is stopped, it must remain stopped for at least x minutes. There is no temperature monitoring during case cleaning. Natural defrost at stop of compressor. Showing of a negative figure spells problems.
HVAC Danfoss Electronic Temperature Controller type Danfoss EKC A B for Freezer
Operating status The controller goes through some regulating situations where it is just waiting for the next point of the regulation. But you can also use a sensor with another signal accuracy. Signal from DI input A Contact details entered above are not used to send newsletters or other advertisements. This view will continue up till 15 min. The display shows the actual room temperature, but by activating the keys the display changes Dantoss the set or the actual temperature of the defrost sensor.
The relay is cut out during normal operation and cuts in in alarm situations and when the controller is dead de-energised Refrigeration 2.
