1-Wire

Sure, that'll work. Added: (not the beating your head part)
Or you could just use 25.

OWOUT DQ, 1, [$CC, $4E, 25, 0]

High limit = 25°C
Low limit = 0°C

If you want to use negative alarms, it's easier to use a variable

LowLimit   VAR BYTE
HighLimit  VAR BYTE

HighLimit = 20
LowLimit = -10

OWOUT DQ, 1, [$CC, $4E, HighLimit, LowLimit]

Do you know how to read the alarm status yet?
