Aprilaire 600A from A58 humidstat to old 60 humidistat.
I have a similar issue with my Aprilaire 600, and have tried the above wiring, but still cannot get the solenoid going. Here is how it' wired up:
R an C are connected to a 24v transformer on the side of the furnace, which is connected to the power supply 'before' the furnace control.
W is connected to W on the furnace.
I have the R on the humidistat connected to the Solenoid as well.
A jumper from the C to the 'left H on the humidistat, and the 'right' H connected to the other solenoid wire.
There is also a 'Com 24v' terminal on the furnace board. That red wire was previously connected to the 'Cf' on the old 58 Humidistat. now not connected to anything.
W was previously connected to the 'W/G' on the 58.
I separated this as your humidistat is not like the A60 as shown in the thread you posted in.
You have an Aprilaire 60 old style.... no A & B terminals.
The wiring between the transformer, R and C and the HUM terminals is not polarity sensitive.
The cable/wiring that goes from W and C on the humidistat to W and C on the furnace board must be followed.
MODEL: TUD100R9V3k4
experiencing issues with hooking up the manual stat to the furnace. After connecting the 5amp fuse popped does anyone know the appropriate way to connect? I am being told by the installer I will need to buy the automatic stat seperately in order to install and he reduced the blower speed to the lowest setting to accomodate the amps. Thanks.

Need some help wiring 700M to goodman GMSS92. I was going to wire it like so
AprilAire Relay 50 - white wire from blower to relay metal bracket, one line from relay to C on the board, the other line to humidifier solenoid
Humidistat - one lead to front facing pressure switch , one lead to solenoid on humidifier
The front facing switch connection is circled on the image, is that correct place to wire humidistat?
