Maybe I'm just thick headed but I cant get this module working right.
I'm controlling supply air temp by turning on/off 2 compressors.
I want lead compressor to turn on and if after a time it's not able to make
60 degrees, I want #2 to turn on. I have other parameters but they're all working. Right now I get 2 compressors all the way to SA low.
SA temp High control = 70 low control = 52 input on inc@
Stage 1 % 60 Stage 2% 40 diff %20
comp 1 is Stage 1 first of 1
comp 2 is Stage 2 first of 1
Hoping that's enough data.
Not much hair left, please help.
