Carrier RTU trouble light
I've noticed that a number of carrier units that i've done planned maintenance on have had the trouble code 1 "fan delay modified" or some such message. A couple of guys I work with said not to worry about it.
Out of curiosity, does this trouble light have something to do with an after market Low ambient Control mechanism? I live in vancouver, where the shoulder seasons often require fan cycling on the condensers to maintain head.
Any explanations as to why the light is going off would be great. I hate not knowing why a unit is doing something.
