NOTES:
(1) See Duty Cycle diagram
(2) If relative values are present (par. Att=1) parameter HAL is set to positive values and the parameter LAL is set to negative values (-LAL)
(3) Refers exclusively to high and low temperature alarms
(4) when changing from °C to °F or vice versa the set points, differentials, etc. are NOT converted (for example, “set=10 °C becomes set=10°F”)
(5) CAUTION: positive or negative values change polarity, Positive values: active input when contact is closed; Negative values: active input when contact is open.
(6) If the Fpr parameter is used, the data previously stored on the Copy Card will be permanently lost.
This operation cannot be undone
* Value: to be compiled manually by user with any custom settings (if different from default settings)
** Level: indicates the visibility level of parameters accessed using a password (see relevant paragraph)
*** PA2 is visible at level 1 in the CnF folder whereas it can be modified at level 2 in the diS folder
