Temperature Status & Power Output
This display shows the current temperatures from probe. If an error occurs a description will be shown instead
of the output information. The setting the device is trying to achieve is in parentheses. When ramping is
enabled for temperature the value in parentheses will change according to the time based curve.
Special Symbols:
Next to the number of the output an arrow symbol will appear if that output is currently in a ramping session. A
right arrow (
→
) will appear if the ramp is increasing. A left arrow (
←
)
will appear if the ramp is decreasing.
Next to the number of the output a minus sign (
-
) will appear if a Low Alarm has been breached. A plus sign
(
+
) will appear if a High Alarm has been breached.

This display indicates the highest and lowest temperature level recorded for the probe and the time at which it
was recorded. Pressing the + button will reset the High/Low to the current reading.

This display indicates the current time schedule the output is adhering to.
