Temperature control can be achieved either by heating or cooling. Please refer to the following for the operation: Settings for heat or
cool operation are found in the initial settings mode under

Depending on the controller model, there can be up to two alarm outputs. Each alarm output can be configured for an alarm type
listed below. Alarm types are set in the initial setting mode. The alarm output is activated whenever the process temperature value
(PV) is getting higher or lower than the set point of alarm limit.

0 Alarm function disabled
Deviation upper- and lower-limit:
1 This alarm output operates when PV value is higher than the setting value
SV+(AL-H) or lower than the setting value SV-(AL-L).
Deviation upper-limit:
2 This alarm output operates when PV value is higher than the setting value
SV+(AL-H).
Deviation lower-limit:
3 This alarm output operates when PV value is lower than the setting value
SV-(AL-L).
Reverse deviation upper- and lower-limit:
4 This alarm output operates when PV value is in the range of the setting value
SV+(AL-H) and SV-(AL-L).
, the program will start to execute in order from the step 0 of the start pattern.
