• Humidification, Dehumidification function:
Dehumidification Mode:
When the measured Humidity is higher than or equal to the set value
+ hysteresis, the relay picks up to start the output; When the measured Humidity below the set
value, the relay off and close the
output.
Humidification mode:
When the measured Humidity is higher than or equal to the set value,
the relay off, turn off the output; When the measured Humidity below the set value - hysteresis,
the relay picks up to start the output.
Example for Setting: If it is set to Humidification mode, set the Humidity to 75%, hysteresis is set to 5,
then when the measured Humidity is higher than or equal to 75%, the relay is off, close the output.
When the temperature is below 70%, pick up the relay again, to start the output.
Example for Setting: If it is set to Dehumidification mode, set the Humidity to 75%, hysteresis is set to
5, then when the measured Humidity is below 75%, the relay is off, close the output. When the Humidi-
ty is higher than or equal to 80%, pick up the relay again, to start the output.
• Humidification, Dehumidification mode setting:
Press “SET” key and hold more than 3 seconds to enter the menu display, the screen appears
“HC” code, press the “SET” key to display the working mode, press the “
▲
”
or
“
▼
” to adjust the
display, C means Dehumidification mode; H means Humidification mode.
• Hysteresis function:
Hysteresis setting limits the maximum interval between the opening and stopping, this machine
minimum interval between the opening and stopping is 1 %, the maximum is 15 %.
• Hysteresis settings:
Press “SET” key and hold more than 3 seconds to enter the menu display, with “

or
“
▼
” key
adjusted to the screen, appearing “D” code, press the “SET” key to display the hysteresis set va-
lue, press “
▲
”
or
“
▼
” key to adjust the parameters.
• Humidity calibration function:
When there is deviation between the measuring Humidity and standard Humidity, use the Hu-
midity calibration function, make the machine measurements value consistent with the stan-
dard Humidity, the after calibration Humidity = the before calibration Hu calibration va-
lue (calibration value can be positive number, negative number, and 0).
• Humidity calibration settings:
Press “SET” key and hold more than 3 seconds to enter the menu display, with “
▲
”
or
“
▼
” key
adjusted to the screen, appearing “CA” code, press the “SET” key to display the temperature cali-
bration settings, press “
▲
”
or
“
▼
” key to adjust the parameters.
For example: When we measure the probe Humidity was 75 %,it displays 75% as the CA is 0, it displays
76% as the CA is 1, it displays 74 % as the CA is -1. This function is generally applied when the probe
can not measure directly the measured object.
• Delay Protection Setting:
Press “SET” key and hold more than 3 seconds to enter the menu display, with “
▲
”
or
“
▼
” key
adjusted to the screen, appearing “PT” code, press the “SET” key to display the delay setting va-
lue, then press the “
▲
”
or
“
▼
” key to adjust the parameters.
• Upper and lower limit functions:
The setting of HS and LS limit the set range of control Humidity point, for example: HS is set to
75, LS is set to 50, the control Humidity can only be adjusted between 50 and 75, when the con-
trol Humidity to 50 then press “
▼
” key, the display will remain on the status of 50 and not de-
crease; when the control temperature to 75 then press “
▲
” key, the display will on the status of
75 and not increase. If the set point outside this range, it needs to firstly change the value of HS
and LS, then it can be achieved.
• Upper and lower limit settings:
Press “SET” key and hold more than 3 seconds to enter the menu display, with “
▲
”
or
“
▼
” key
adjusted to the screen, appearing “HS” or “LS” code, press the “SET” key to display the upper or
lower limit set value, then press “
▲
”
or
“
▼
” key to adjust the parameters. HS means upper limit.
LS means lower limit.
