I changed old one with new controller but it can not work.
Controller is for cooling chamber (cold room).
Situation is next:
-on the left side 3 leds blink all the time
-I checked parameters ...it's OK
-if I understand I must hold top button few second to see alarm message
-massage is A42 ....but I don't have that alarm message in list ....so I don't know meanings

Make sure parameters o02 and o37 are set to "off" to begin with (these are the digital input functions), then once you have it running if you need to use the digital inputs then program them in and test them one by one.

I changed parameter r12 from 0 to 1.After that alarm A45 was disappeared and also LED,but I have new problem.
Now regulator can not start compresor.
I think that is necessary to change some more parameters.
Question is which one???

I replace this danfoss regulator and put new LAE.
Working very good.

A45 is an alarm
A45: Standby position (stopped refrigeration via r12 or DI input
