The range above/below set point
in which no control action takes
place. Determines at what
temperature the output switches
ON and OFF. For a 5°F dead
band, 2.5°F is above and below
the set point. This menu is active
when the dip switch is set to
“ONOF”.

Temperature level that will
actuate the alarm.
Alarm Dead Band
Difference of temperature from
alarm set point before an active
alarm resets.

may be set without security
code access. This prevents an
operator from setting the set
point temperature to a level
which would damage
equipment or process.

Cycle Time
The time for the output to
complete ON to OFF to ON
cycle. Used only with
proportional control. A fast
cycle time provides better
control, but can cause
premature wear to contactor or
other power switching devices.
Magnetic contactors should not
be switched at less than a 30
second cycle time. This menu is
active when the dip switch is
set to “PI”.
