Speed presets using override 2 mode HVAC ACH550 + Bypass
My name is Helmer, I'm working with an ABB VFD: HVAC ACH550 with an E-Clipse Bypass, I connected the drive to a FAN and I need to change its speed deppending of the temperature of a certain room. I want to change the speed trough speed presets.
Question is: In override 2 mode you have 2 reference source to change speed (param 1707) constant and PID, constant speed can only be change trough override frequency (param 1702) or can it be changed trough speed presets (param 1201) ?
Thanks for your time.
