Notes:
1. If you select a type for the alarm, the alarm set value in the AREAs are reset to default values as follow:

2. The alarm standby operation is active when the power is turned on, when target settings are changed in
AUT mode, and when the mode is changed from MAN to AUT.
It is suppressed in REM analog input mode operation even if alarm with standby operation is selected.
3. The input error refers to an error in measurement input, remote analog setting input, or external area selection
input.
4. Exciting refers to the excitation of the alarm relay when an alarm condition is met, resulting in the N/O
contact of the alarm relay to close.
Conversely, non-exciting means the NO contact will open.
5. Use the same unit specified in the measurement input unit.
6. This item is not displayed, if the control output (the heating control output when in the heating, cooling
PID operation) is a relay output.
7. This item is not displayed if the cooling control output is a relay output in the heating, cooling PID
operation.
