Firstly thanks for using our instrument. This
product is a new product of fully automatic
intelligent control sy-stem especially made for
high-temperature and heating industry.
Wh e n cu r re n t te m per a tur e is
higher than the upper limit, the
screen will display “E2” and the
load will be off.

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 aga in, and then
connect it to the power for running.
2. Keep away this product from moist or corrosiIve air and high
magnetic field. Otherwise the normal operaton 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) 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!
About Failure
Failure
No display when power
is on.
Displayed temperature is
unstable or there exists
misplay..
“EI” is displayed The sensor wiring is short circuit or
open circuit.
Check to see if the sensor wiring has good contact
with coupling end or not.
Check to see if the power is short circuit.
The thermostat fails.
The set temperature is higher than the present
temperature.
The heat protector is open circuit because the
pressure is over loads.
The sensor wiring is interfered, poorly contacted or
is tied with other cables. The current is light because
of damage in the wiring.
The locations for the sensors are not correct or
sensor wiring is too long and its resistance is too
big. The wiring contact is poor and the sensor`s
damag.
The sensor is not correctly installed and cannot
measure the correct temperature. Compressor
contactor fails.
Check power supply and change fuse.
Check if there is 220V power input or change
thermostat with our distributor.
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 wiring sealing, is good.
Change sensor.
Check if the sensor has accurately measured the
temperature or not. Change compressor contactor.
Causes Precautions
Difference with temperat-
ure within storage and the
displayed temperature is
too big.
Machine does not stop
when the temperature
reaches.
Machine does not work
but display exits

Feature descriptions
Note:When a high temperature alarm settings should be greater
than the set temperature and hysteresis sum
When you set the temperature alarm should be less than the set
temperature minus the hysteresis sum.
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.
