Parameters (Screen 1: Alarm Values)
NOTE: The temperatures in this screen are differential values.
Standby temperature
= Setpoint temperature - Standby value
The minimum standby temperature is 40 °C (100 °F), even if the selected
settings would (mathematically) permit the standby temperature to be lower.
Standby value: 50 °C (90 °F)
The values* are not a factor of the setpoint during the heatup and cooling
phases (Refer to Monitoring of Heatup and Cooling ).
When the ALL, ALL HOSES and ALL GUNS groups are used, the values for
warning and fault are always assumed together, even if only one of the
values has been changed. This ensures that the fault value is always larger
than or equal to the value for the respective warning.

NOTE: The warning value is a factor of the fault value in that the values for
the warning may not be larger than the corresponding values for the faults.
When appropriate, first increase the fault value.
