According to this chart.

I think a 2200 ohm NTC will add 2.2kohm @ 25c 77f and only 153ohm @ 100c 212f
The servo has a 5k reastat.
With power only the control bord is looking for ~2.5k ohm.
This will caus the servo to be centered/closed @77 and progressively opening to full by 212f

I tested with a 91ohm NTC to day. It worked but verry small movement on the servo to compinsate for the small change .
This NTc was 91ohm @77f and 12ohm @212mesuerd. 79 ohm change =very small light movement.in other words the slave bearly moved because of very low amperage sent.
