Hi Guys

This is the cause of my problem, info from Ahsai on Renntech:-

Hi Ahsai

I will check the servo.

So the servo should move the flap bit by bit when you change the temperature setting ?

Cheers




Neil.
Exactly. The servo should move the flap proportional to the temp setting. It should be able to stay partially open so it can modulate the air temp by mixing the right amount of hot air with cold to get the exact temp setting you chose.

In other words, as you change the temp setting gradually, the flap should move bit by bit. That's why there's a potentiometer inside the servo that provides a varying output depending on the degree of opening of the flap. I hope that makes sense.
