Fan
button turns the fans On or Off, if manual opera-
tion is enabled, but has no effect if manual operation is
disabled.
In the

mode,

are above the programmed setpoint.

has no effect if audible
alarm is disabled.
If there is no alarm condition, pressing

tests the

again silenc-
es the alarm.
Alarms can be set to be latched or unlatched, (Latched

lecting data about the type of alarm, the time and date of
the alarm, and the temperature of each thermocouple at the
time of the alarm. The TC-100 stores such alarm data for up
to 25 alarms.
