injector duty cycle question how it controls the aquamist

[Richard L]

The default setting on the HFS3 mirrors the incoming IDC at 1:1 ratio. If you want the HFS-3 to inject 100% DC with a 80% incoming IDC signal, just use the gain trimmer.

One easy way to achieve this is by observe the red 95% DC led, just advance the gain trimmer until this led just come on. There is no progression in flow beyong 95% DC
