Set control sensibility of alarm output.
Temperature Setting Group
●
The set point is indicated by flickering at every
0.5 seconds intervals and this set point can be
established by using th

key.
After changing set point, it displays the current temp.
●
If there’s no input made for a period of 60 seconds during the setting,
then it returns back to the run mode automatically.

Deviation High Limit Alarm
Output is ON when the deviation between
PV value and SV value is higher than setup
value of deviation temperature.
Deviation Low Limit Alarm
Output is ON when the deviation between
PV value and SV value is lower than setup
value of deviation temperature.
Deviation High & Low Limit Alarm
Output is ON when the deviation between
PV value and SV value is higher or lower
than setup value of deviation temperature.
Deviation High & Low Limit Reverse Alarm
Output is OFF when the deviation between
PV value and SV value is higher or lower
than setup value of deviation temperature.
Absolute Value High Limit Alarm
Output is ON when PV value is higher than or
equal as alarm temperature setup value.
Absolute Value Low Limit Alarm
Output is ON when PV value is lower than or
equal as alarm temperature setup value.
Sensor Open Wire Alarm
Output is ON when sensor wire is opened.
No output within Min. OFF time
after control output #1 OFF.

parameter of sensor input of setting 2 group.
※ FX3DH controls by measured value which is detected by sensor.
If sensor fault alarm occurred as following, please check wiring with sensor
※ In case of the above-mentioned error, it will be normally operated with cancelling error
status if the reason of error is solved.
In the case of Humidity display,
