humidifiers exceeding 1200 Watts (120v)/ 2200 Watts (220v).
DO NOT touch the terminals at least while power is being supplied. Doing so may
occasionally result in injury due to electric shock.
DO NOT allow pieces of metal, wire clippings, or fine metallic shaving or filings from
installation to enter the product. Doing so may occasionally result in electric shock,
fire, or malfunction.
DO NOT use the product where subject to flammable or explosive gas. Otherwise,
injury from explosion may occasionally occur.
DO NOT disassemble, modify or repair the product or touch any of the internal parts.
Electric Shock, fire, or malfunction may occasionally occur.
If the output relays have been used over their life expectancy, contact fusing or
burning may occasionally occur. Always consider the application conditions and use
the output relays within their rated load and electrical life expectancy.
DO NOT immerse any components of the controller in water.
FOR INDOOR USE ONLY.

5.1 Control Range Setting
MD: Mode Setting
MD=H, being in Humidity Setting Mode, user can set humidity parameters in the following
menu;
MD=T, being in Temperature Setting Mode, user can set temperature parameters in the
following menu;
5.2 Humidity/Temperature Control (HD, HS, DS/ HC,TS,DS)
In Humidifying/Heating Control Mode (HD=H, HC=H)
When the measured humidity (temperature) drops down to HS–DS (or TS-DS), the
output will be on and the indicator lamp will light up; When the measured
humidity/temperature reaches the set value HS (TS), the output will be off and the
indicator lamp will be off too.
In Dehumidifying/Cooling Control Mode (HD=D, HC=C)
When the measured humidity (temperature) rises to HS+DS (or TS+DS), the output will
be on and the indicator lamp will light up; when the measured humidity/temperature
reaches the set value HS (TS), the output will be off and the indicator lamp will be also off.
5.3 Alarm Limit Setting (AH, AL)
When the measured humidity (temperature) higher than AH, the humidity (temperature)
high alarm will be on; when the measured humidity (temperature) lower than AL, the
humidity (temperature) low alarm will be on.
When alarm is on, the display will be flashing between the measured value and alarm code
with the “BI-BI-BIII” sound. The alarm sound can be stopped by pressing any key but the
status of alarm will be not change until the value of measured humidity/temperature
return to the normal range.
5.4 Compressor Delay (PT)
Under dehumidifying (cooling) control mode, after power on, if the measured humidity
(temperature) higher than HS+DS (TS+DS), the equipment won’t start
dehumidifying/cooling control immediately, but waiting for a delay time.
When the time interval between two dehumidifying (cooling) operation (or the time from
power on to dehumidify (refrigeration) is larger than preset delay, the equipment will start
dehumidifying (cooling) control immediately; when the time interval between two
dehumidifying (cooling) (or the time from power on to dehumidifying/cooling) is less than
preset delay, the equipment won’t start dehumidifying (cooling) until preset delay is
satisfied.
Delay time will be calculated once dehumidifying (cooling) stops.

5.5 Calibration (CA)
When there is deviation between measured value and actual value, the value can be
calibrated by setting the CA. The corrected value is equal to value before calibration plus
corrected value (corrected value could be positive value, 0 or negative value）.
5.6 Display in Fahrenheit or Centigrade unit (CF)
Fahrenheit or Centigrade degree displaying can be selected as needed. Default displaying
is in Centigrade degree. Please set CF to F to change the displaying in Fahrenheit degree if
needed.
Attentions: After CF value changed, all the setting value will be recovered to factory
settings.
6. Error Description
Sensor Fault Alarm:when sensor is being in short circuit or open loop, the controller
will initiate sensor fault mode by stopping all the operation with the buzzer alarming and
ER displaying. Buzzer alarming can be dismissed by pressing any key. And the controller
will return to normal working mode when the fault was removed.
