Setting Method of control mode
※ According to user's setup, FX3DH is able to use humidity only or temperature
only or for both temperature and humidity. Please use after you setup the
parameter of sensor input of setting 2 group.
I N
Setup sensor input of setting 2 group.
Use for humidity only
H
Use for temperature only
T
Use for humidity and temperature control
HT
(Output1: humidity control, output2: temperature control)
Humidity and temperature are displayed by every
2.5 sec. interval in shifts.
Use for humidity control and temperature display.
HTD
Humidity and temperature are displayed by every
2.5 sec. interval in shifts.
Simple Trouble Check Point
※ 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.

established by using the ▲ key or ▼ 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
A L 1
Output is ON when the deviation between
PV value and SV value is higher than setup
value of deviation temperature.
Deviation Low Limit Alarm
AL2
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
AL3
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
AL4
PV value and SV value is higher or lower
than setup value of deviation temperature.
Absolute Value High Limit Alarm
AL5
Output is ON when PV value is higher than or
equal as alarm temperature setup value.
Absolute Value Low Limit Alarm
AL6
Output is ON when PV value is lower than or
equal as alarm temperature setup value.
