You will need to replace your ST-2E zone board with the NCM-3z. NO new wiring if you are not putting a WIFI stat on the 2nd zone. If you are planning on putting a WIFI stat on zone 2 then "Yes" you will need to run more then 3 wires to that zone.

This is an older damper that we do not manufacture anymore and there is no replacement motor for this damper you will need to replace the entire damper. The damper you need will be the ND series damper.

If you need more info give us a call 1-800-446-3110

It is normal behavior for your fan purge. You can lower it or turn it off.

No the UT-3000 must have a stat for each zone. Sensors will not work.

Set your BMPlu-3z for staging just like the old BMPLus-3000 do not set it for weighting.

NO our UT-3000 does not float our dampers. I agree having the UT-3000 float our dampers would be a great idea.

BMPlus-3z is the same as the BMPlus-3000 Instead of the Dip Switches now you will set your settings by pressing the 4 buttons in the middle of the screen.

Please give us a call on this issue. Thank You.

There is a gap between the damper and the duct work. Pull out the damper and put some gasket on the top and bottom of the damper and place the damper back into the duct. Whistle noise should be gone.
