Description
Enable or Disable the Heater feature and temperature monitoring.
Tap the switch button at the top of the screen to toggle the feature
On or Off. The default is On.
Tap the button to switch between Automatic mode or Manual
mode. To learn more about the modes, see
Works on page 26 and How Manual Mode Works
Set the sensitivity of the cold storage exit trigger by defining a
DeltaT value. To detect a cold storage exit, the computer looks for a
quick rise in temperature (°C), over a brief period of time. The default
DeltaT value is 0.5 °C.
Set the length of time (minutes) the heaters stay On at full power
(100%) once the computer detects a quick rise in temperature
(DeltaT value, see above).
The default value is 5 minutes.
Note: The heaters may turn Off before the timer has expired if a
temperature reading indicates the computer is warm enough
or you manually turn Off the heaters by tapping the heater icon
once.
Set a low battery charge threshold (%) that triggers the computer to
turn Off the heaters to conserve battery power.
The default value is 25%.
Note: Setting a value lower than the default of 25% may negatively
impact device performance.
Set the temperature (°C) that the computer must fall to before the
system determines cold storage entry and heater use. Once this
temperature is detected, the Chill time starts.
Set the time limit (minutes) for how long the computer must remain
at or below the defined Heater enable temperature before the
system initiates one of the following actions:
• If in Automatic mode and Preemptive Heating is disabled,
the system turns the heaters on when a cold storage exit is
detected (see DeltaT value).
• If in Automatic mode and Preemptive Heating is enabled,
the system starts the Preemptive Delay Time.
Note: If you remove the computer from cold storage before the
Chill time expires, the system does not turn On the heaters,
saving battery power.
Enable or disable Preemptive Heating (pre-heating) when
Automatic mode is enabled. Tap the check box to toggle the feature
On or Off.
Set the percentage of time that the heaters are on during
Preemptive Heating.
