Question Problem with Model 60 (Converting from prev)

I have a AprilAire 600 that had the original non-digital control that quit working. I have installed the Model 60 - first got an "r1" error - but now shows humidity % and appears to turn off & on visually - but solenoid never moves. (It did work previously)

I tried the usual flipping switches auto to manual etc and never got solenoid to click.

Attached is before & after wiring

Old had red & white to the 24V terminals, which were connected to "R" and "C" on new - I connected them to "R" & "C" on new. (Red wire to "R" on old and new)

Old had Solenoid two wires connected to two "H" posts - did same with new.

The outside sensor was wired to ODT on old and did same on new. I had replaced the outside sensor recently so did not do new one - but switched to manual to bypass it and also hookedup dummy sensor that I had for overriding the old faulty one. (No solenoid action from any of this.)

Checked wire connections to solenoid.

Furnace is a Bryant with two zones and complicated control box - but I "assume" that if the old AprilAire control worked using the six wires - the new one should also.

Seems pretty straightforward - Anybody got any suggestions?? (Thanks)

Welcome to the forums.

I was going to move you to your own thread but here will work out better.

Did you look at the diagram in post 2 ?
You'll notice there are 7 wires connected to the h'stat. It requires a W connection to your furnace control board to operate.

Yes - I ran a temporary wire from W in Honeywell HZ311 control panel. I have two zones so there were W terminals where each thermostat is connected plus another W in the "Equipment" area. I connected to the "Equipment" one and had no improvement. (Solenoid does not engage) Attached are two pictures of HZ311 - the thermostat connections are in blue on each side near top. The "Equipment" connections are in gray about half way down on left side. Any further suggestions? (If pictures do not upload I will re-post) ThanksName:  HVAC2.jpg
