Thanks Erik for walking me through it. I've ordered new damper motors.

Hello EWC,

I have upgraded my panel from a ST-2D model to a BMPlus 3000 model keeping the existing dampers and motors.

Is there any way to configure the panel so that the damper remains closed as a default?

The reason I'm asking is that Zone 2 is called then stops, after cooling has eneded, Zone ...

Yes, its the lower left corner I was talking about. Starting to make sense.

Thanks Patrick!

I understand that now, use the G wire as your new C wire everywhere.

The ST-2D panel has a R connection (bottom right) however the BMPlus 3000 panel (system) has no such letter connection.

What do I do with the R (red) wire?

Thanks,
Bob

Thanks Patrick,
Does the G wire have a constant 24v running through or just when the fan is activated?

I currently am using a ST-2D split zone with forced hot air and A/C. My thermostats are wired as:

Master (1st floor)
R - red
O - orange/red
B - blue
W - white
G - green
Y - yellow

Secondary (2nd floor)
R - red
Y - black
W - yellow
G - green

I have no C or X wire to power a programmable thermostat ...
