6 Cold Limit This value can only be changed in engineering mode. Section 6.7 describes how
to access engineering mode.
Enter a lower temperature limit. If the sensor temperature falls below this limit, the gas flow
is disabled.
7 Hot Limit This value can only be changed in engineering mode.
Enter an upper temperature limit. If the sensor temperature rises above this limit, the heater
is disabled.
8 Cut off This value can only be changed in engineering mode.
This is an additional safety feature, normally set to the end of the calibration range. An
external input from the auxiliary I/O card (if fitted) cuts off the heater if the sensor reaches
the indicated temperature.
