Sit Proflame 1 DFC Faint Beeping

Everything with the fireplace works fine, but my Proflame DFC module emits a very faint beep every half second. It's driving me nuts.

When the switch is set to CPI, the beeping always occurs. When the switch is set to IPI, the beeping occurs only when I turn on the fireplace either with the remote or using the ON position on the receiver.

I've replaced the batteries in the remote, the batteries in the receiver, and the single 9V battery in the mess of wires underneath by the control module. The beeping doesn't stop! Can anyone help?
