3. SETPOINT LOCK OUT JUMPER: This jumper controls
whether the user is allowed to reduce the setpoint below
48°F or 9°C. If the jumper is in position 1 (farthest from
the SPL label) the user IS NOT ALLOWED to reduce the
setpoint below 48°F or 9°C. If the jumper is in position 2
(closest to the SPL label) the user is allowed to reduce the
setpoint to 10°F or -11°C.
4. TEMPERATURE DISPLAY JUMPER: If this jumper is in the
