Key Operation
Temperature and humidity setting
Keeping〖S〗pressed for 3s to enter temperature and humidity setting mode, digital shows set temperature.
Press〖P〗choose humidity and temperature value circular, press〖▲〗or〖▼〗change the value(Keeping〖▲〗or〖▼〗
pressed, it will be adjusted quickly)
After setting, press〖S〗to exit and saving parameters. Do not press any key for 30 seconds; the device will leave the set mode
without saving the set data.
Set system parameters
Keeping〖P〗pressed for 3s to enter parameters setting mode, digital shows parameter code, at the same time press〖▲〗or
〖▼〗to choose parameter code.
Press〖S〗to shows its value. Press〖▲〗or〖▼〗to set its value.
Keep depressing【P】for 3 seconds, the set parameters will be saved, the mode exits.
If do not press any key for 30 seconds, the mode will exit without saving all the set data.

Control function instruction
Temperature control
Cooling control:
◇
When the temperature≥【setting temp.】+【temperature difference】,and temperature load (R3) stop time meet【temp. load
delay protection】,temp. Load on;
◇
When the temperature≤【setting temp.】,temp. Load (R3) off;
Heating control:
◇
When the temperature≤【setting temp.】-【temperature difference】,and temperature load stop time meet【temp. Load delay
protection】, temp. Load (R3) on;
◇
when the temperature≥【setting temp.】, temp. Load (R3) off.
Humidity control
Dehumidifition control
◇
when humidity ≥【setting humidity】+【humidity difference】, and humidity load (R2) stop time meet【humidity delay load
protection】, humidity load on
；
◇
when humidity ≤【setting humidity】, humidity load (R2) off
Humidification control
：
◇
When humidity ≤【setting humidity】-【humidity difference】, and humidity load (R2) stop time meet【humidity delay load
protection】, humidity load (R2) on
；
◇
when humidity≥【setting humidity】, humidity load (R2) off
Dewing warning
When humidity get to dewpoint, after【dewing warning delay】controller enter dewing warning state. If【dewing warning way
】
is C, digital shows”E2” alarm, humidity load output stop, warning output (R1) on. If【dewing warning way】is V, digital
shows”99.9%”alarm, still output.
Timed control
Timing circle control:
◇
When enter timing load 1 timing 1, timing load 1(R5) on, timing load 2 (R4) off.
◇
When enter timing load 1 timing 2, timing load 2 (R4) on, timing load 1 (R5) off.
◇
When enter timing on 2, timing load 3(R1) on.
◇
When enter timing off 2, timing load 3(R1) off.
Load delay protection
◇
Controller power is on, all load output (R2 R3) run after load delay protection
；
◇
Running process, the temperature and humidity load (R2 R3) after downtime must be after load protection delay to start
again.
U
pper temperature and humisity limit protection
◇
U60=3, R1 is timing relay. When temperature or humidity beyond the limit, R1 turn on, R2 R3 off, R4 R5 still the same
◇
U60=2, R1 is timing function. When humidity or temperature beyond limit R1 turn on.
◇
U60=1, R1 is timing function, limit protecting function stop.
Sensor
◇When the sensor broken controller shows”E1”, humidity and temperature load off, warning output on.
4th
◇When the display value is different from real value, it can be correct by【 humidity(temperature) value
correction】range is ±9.9%；
◇Do not change Sensor or connecting ways, when the power is on
Factory setting:
Keep【P】and 【▲】keys pressed for 5 seconds, the device displays “UnL”, press 【▼】 twice controller
will reset auto. Default password is「0000」.
Controller Installation
Warning：
Avoid installing the device in the following environment:
● Relative humidity is greater than 90%, or possibly dewing.
● Strong vibration.
● Possibility be dropped, or within fog.
● Exposed to eroding and polluting gases (such as: air containing sulfur and ammonia, salty fog, smoky mist) to
prevent erosion and oxidation.
● Ambient containing explosive or inflammable materials/gases.
Installation Procedure
Insert the controller into hole (step one) Slide the bracket to fix the device (step two)
Electrical Connection
Warning
● Electrical wiring must be manipulated by certified electrician.
● Wrong power supply may damage the device and system seriously.
● Try with effort to layout the sensors and switches line apart from inductive load lines and power supply lines.
The sensors and switches lines are not allowed go with the power supply lines and inductive load lines in a
same pipeline, and are not allowed to pass near the contactor, breaker and the similar.
● Reduce the length of sensors’ wiring as possible, avoid forming a spiral shape near the power devices.
● Avoid direct contact with the internal electronic components.
● After finish and check the electrical wiring layout, before connect them to the device, please follow this
instruction: Pay attention the “electrical wiring diagram” below, wrong connection possibly damages the device
and the system, and may be dangerous to the user. All security and protecting device for the equipment are
necessary. They are very important to protect the equipment, and the user’s safety.
