EWELLY is an enterprise which is speciallized in pro
-ducing eletronic controller.We always insist that quality
of product and best service is our goal.
Our sensor is especially precisely made and sealed; it
is moisture-proof , therefore its performances are more
stable and reliable.

Brief on Operation
1.The voltage must accord with controller's demand. The
voltage's deviation is no more than ±10%.
2.The loop of sensor is possible to keep away from the
loop of power.
3.The sequence of line's must have been connected
Properly.

Warnings
1. Please read this product instruction carefully and connect
input/output plugs of power & sensor to the corresponding sockets
strictly by following connection diagram, otherwise the usage &
operations will be affected. Check again to make sure there is no
mistake. Tighten all the screw of connection plugs again, and then
connect it to the power for running.
2. Keep away this product from moist or corrosive air and high
magnetic field. Otherwise the normal operation of this product will
be affected.
.
3. All our products have passed strict quality inspections before
leaving factory. We provide one-year quality guarantee (which is
limited to product itself ,and is not responsible for any other joint
and several liability) period for this product. If you have any doubt or problem concerning the electronic
temperature or humidity controller made by us, please contact
our distributors and we will provide you high-quality after-
sale services. Thanks!
Failure
No display when power
is on.
Displayed temperature is
unstable or there exists
misplay.
Relay work with
overload
“EI” is displayed
Check to see if the sensor wiring has good contact
with coupling end or not.
Check if the power is broken or the
thermostat failture.
The setting temperature is higher than the
present temperature.
The heat protector is open circuit because the
pressure is over loads.
The sensor is not correctly installed and cannot
measure the correct temperature. Compressor
contactor fails.
Return difference value is too small or the
setting for pressure protection is not correct.
Check power supply and change fuse.
Reset the necessary controlling temperature.
Check the reasons for overload and overheating.
After the trouble is solved, restart to work.
Separate sensor wiring with power cables or change
shielded lines or check if the contact is tight or not.
All sensors should be corrected at their locations.
Enlarge the cross section of the expanded wires.
Make sure the wires sealed is good. or Change the
sensor.
Check if the sensor has accurately measured the temperature
or not. Change compressor contactor.
Reset and enlarge return difference value. Adjust
setting for pressure protection.
Causes Precautions
Measurement error between
current temperature and
displayed.
Machine does not stop
when the temperature
reaches.
Displaying and machine
doesn't work

Feature descriptions
Cooling: When the current temperature ≥ setting temp-
erature + temperature hysteresis and delay the setting of
the "delay time" , the load relay On.
Cooling stop: When the real temperature ≤ the set temp-
erature, the load relay is Off.
Heating system: When the current temperature ≤the setting
temperature - the temperature hysteresis and delay the
setting of the "delay time", the load relay Off.
Heating system to stop: when the current temperature ≥
setting temperature, the load relay is disconnected.
Tips: cooling and heating conversion set in the
parameter H / C menu selection, H is the heating
system, C is cooling.
-45℃ to Temperature control-1℃
Temperature control+1℃ to 80℃
Attention: The highest temperature limited (HS) and the
lowest temperature limited (LS) have been locked. Please
don't change.
Trouble shooting
The sensor is interfered; or poor wiring; or
Together with other power cord bundle；or line
damage.
The sensor is opened or shorted circuit.
Check if the input voltage is right or
change the thermostat with our distributor.

The installation position of the sensor is not
correct; or the sensor's wiring is too long and its
resistance is over; or the wiring connected poor;
or the sensor is damaged
If the products including but not limited to, the following is
not the product itself quality problem caused by the damage,
Install and use under the do not conform to the safe environment;
That the load capacity is beyond the scope of product is allowed;
Products by users to disassemble and change, change the internal
components, etc.,We will not be so and damaged products
provide a replacement and maintenance services, regardless of
whether its in the quality assurance period; Meanwhile, we will
