Where is the volume/tone adjustment? My newly installed chime sounded very dull and low volume.
We would continue to suspect that the transformer is under powered. The Nutone C907 transformer is 16 VAC, however, the wattage is 30 VA. This slight increase may be enough to make the difference. One other thought would be to increase the wire size to a larger gauge, if possible. This should also improve this condition.

How do I get it to go Ding Dong?
It is just going Ding right now?
You are wired to the back door terminal. Leave the wire on the trans terminal and move the other wire to the terminal marked "front" or 1.

Can a single button drive two chimes?
I need a chime both upstairs and downstairs. Can the units be wired so a single doorbell button will cause both to chime? With two doorbell buttons, a front door and a back door, will units wired together correctly chime for both doors, with different chimes for front and back? (All buttons are unlighted.)
If this unit will not provide this can you recommend a wired Nutone unit that will?
The answer is Yes to all. Ideally, each doorbell button wire (the front button and the back button) should go to a box near the transformer and then each doorbell itself should have a dedicated wire from that box to the mounted doorbell. Size the wire appropriately. You will need 18/2 or 16/2 for the doorbell buttons, and 18/3 or 16/3 from the transformer area to each doorbell.
You may already have all this in place, but you must have a new 16v 30va transformer.
