Carrier CC6400 Algorithm Question
I am trying to control a pump by sending a variable 0-10vdc signal using the AO Adaptive Control Algo. I am not using the reset function and my problem is this:
I can't get the signal to decrease on temperature drop. I setup a setpoint schedule that the algo appears only to respond to the lo setting.
So basically right now the output signal rises on temperature drop, and I need it to do the exact opposite.
Any ideas?

AO-Adapative is only going to look at the OccLow & UnOccLow.
In you PID Master Loop change KP, KI & KD to negative numbers and it will reverse the operation of the algorithim to make it Direct Acting.

Thanks Balibe! I'll try that.
Do you know of another algo that would fit my application?
