Section 3.4 says:

1.  Temperature changes in the Temperature Control Protocol are
    indicated by the U+2206 character ("Δ").

It should say:

1.  Temperature changes in the Temperature Control Protocol are
    indicated by the U+2206 character ("∆").

Notes:

This applies to the PDF version only (https://www.rfc-editor.org/rfc/rfc7997.pdf); the issue is repeated in the following lines.

The character on display is 'GREEK CAPITAL LETTER DELTA' (U+0394), not 'INCREMENT' (U+2206).

This was marked "Held For Document Update" per discussion with the Temporary RFC Series Project Manager (John Levine).
