Hvac actuator reset

By Gerix June 30, in Climate Control. Hey guys! I'm brand new here but it seems like there are a lot of folks out there with similar issues and I'm hoping I can get some input from the group. I have the old one out, have the new on in but I cant figure out the best way to calibrate the new one to the system. Basically, I need to have the new actuator in the exact position that the old one died in AND have the touchscreen temperature match that position as well. Am I over-thinking this? What's the best way to get this new actuator calibrated with the position the system is currently in? You may have to run the cal routine a couple of times to get the system back to full functionality. If the position of the new door is significantly different from the point at failure, the system will successively move toward the new correct position setting. It may take two or three cycles for the system to move to the correct position. THank you.
