Selecting the operating program, parameter 0
The TVS has seven configurable programs, A, B, C, D, E, F, and G if you are running a livestock or
poultry operation, you might use different programs for different stages of development. Another
option is to use different programs for different seasons.
The default operating program is program A. Any of the seven programs can be the operating
program. For a list of the factory defaults for the programs, see the table starting on page 55.

Acknowledging alarms
The alarm relay activates if an enabled alarm condition is present for longer than the minimum
duration of one minute. The one-minute minimum duration prevents alarms from occurring when
the temperature rises or drops for just a few seconds.
The exception to the one-minute minimum is the power fail alarm. The power fail alarm automatically
triggers the relay on a loss of power.
When an alarm occurs, the alarm relay activates, the LED for ALARM switches on, and the alarm
message displays. If there is more than one message, after acknowledging the first alarm, the next
one displays.
For example, if you have a high temperature and probe damage alarm, the display shows X-AL.
After acknowledging the high temperature alarm, the display shows pbad. When all alarms have
been acknowledged, the display shows the temperature.
