Carrier Xarios 200

[Stone]

HI
Thanks for adding me to your site.
Have a problem with a Carrier Xarios 200 system.
The unit only switch with a AC supply but with a 4H alarm.
Does not switch on with 12V supply, did measure 12V DC on control box.
If you can help me with the 4H alarm code and any other info.
Thank you very much

i'm pretty sure that you didn't read the code right, code should look like A01,
To run on diesel mode unit most have 12+ from ignition on pin 4(not sure of pin number, but you can check on the wire) on the micro.
If you have 12+ and unit still does not power up, there is a 1 amp fuse in the micro, remove and check

if fuse ok, and have 12v+ on ignition wire i would suspect the micro
