press ▼or ▲button to adjust the value quickly. When adjusting, the number of temperature blinks, which means that
the setting is not confirmed. After blinking for 6 seconds, the setting is confirmed and then it returns to display measured
temperature. appearing on right of the LCD indicates cooling/heating device on working. disappearing indicates
s cooling/heating device stops working.
5. set button : Use to select cooling or heating mode for temperature control . In cooling, symbol appears on the top left
of LCD. In heating, symbol appears on the top left of LCD. Press set button for 6 seconds until or appearing. It
indicates that the cooling/heating mode is locked. Now the working mode can not be changed.
6. Lock the set point：Press ▼and ▲at the same time for about 6 seconds until the symbol appearing on the top right
of LCD, which indicates that the set points of humidity and temperature are locked, after that, it’s impossible to adjust
humidity or temperature by ▼and ▲button.
7. Unlock set point : press ▼and ▲at the same time for about 7 seconds under the locking mode until the symbol
disappearing.
Advanced Setup (V. A031)
Please use the below parameter setup carefully. Don’t change any default setting before you read and understand
all parameters.
Cut off power and press the ears on both sides to take off the main part from the base part. Then you will find a set
of four DIP switches DIP1~DIP4 on the top left of the circuit board.
DIP1: ON—parameters setting OFF—normaluse (leavefactory:OFF)
DIP2: ON—Fahrenheit for temperature display
OFF—Celsiusfortemperaturedisplay (leavefactory:OFF)
DIP3: ON—Dehumidify mode; OFF—humidifymode (leavefactory:OFF)
DIP4: Unuseful for the model
Put the DIP1 to ON (up is ON, down is OFF) and put the main part to the base part, then you can set up the following
parameters. Press switch button to select parameter and set up its value by press ▼or ▲.
Warning: must cut off power before open the controller.
LCD Parameter Range of setup Default
-1 RS485 communication address 1~255 1
-2 RS485 communication rate 1-4800, 2-9600, 3-14400, 4-19200, 5-38400 4
-3 RS485 communication odd/even
calibration and stop bit
1- none 1 stop bit
2- none 2 stop bits
3- odd calibration 1 stop bit
4- even calibration 1 stop bit

-4 temperature modification ±3℃/±6℉0℃
-5 humidity modification ±5%RH 0%RH
-6 maximum limit of temperature setting 0~60℃/32~140℉35℃
-7 minimum limit of temperature setting 0~60℃/32~140℉5℃
-8
differential humidity to control the replay action 0~5%RH
For example, when it is set 2 and humidity set point is 40%RH, in humidify mode, the relay1 will be on when
measurement humidity< setting; if measurement humidity> (40+2)%RH, the relay1 will be off. Dehumidifier
working is in reverse mode.

-9
Differential temperature to control the relay action 0.0~3℃/0.0~6.0℉
For example, when it is set 1 and the setting temperature is 25℃, in heating mode, the relay2 will be on
when measurement temperature< setting; if measurement temperature>(25+1) ℃, the relay2 will be off. In
cooling mode it is in reverse mode.

-10 The state when the controller electrify
again after power broken
0- Turn off after electrify
1- Turn on after electrify
2- Keep the same state before power broken

Reset: in the state of parameter setup (DIP1=ON), cover the main part and turn it on. Press switch for about 25
seconds until the controller turns off. The all parameters reset to default. After finish parameter setup, you must cut
off the power open the main part again, put the DIP1 to OFF, then the controller can work again.
