LED Status Description:
The left side of the display lights as working lights WORK use flash that delayed cooling or heating,
LED lit
Said cooling or heating work.
Display as the left set of the SET indicator light use, LED light is that in the set state.
Function:
Press the RST key to open the thermostat, running, press the button for 3 seconds, turn off the
thermostat.
◆ refrigeration, heating function:
Cooling Mode: When the measured temperature greater than or equal to the setpoint + hysteresis, the
relay, starting out; when
Measuring the temperature below the set value, the relay off, turn off the output.
Heating mode: When the measured temperature is higher than or equal to the set value, the relay off,
turn off output; When measured
Temperature below the set value - hysteresis, the relay will start the output.
Setting example: If set to heating mode, set temperature of 25 degrees, hysteresis is set to 5, then when
Measured temperature is higher than or equal to 25 degrees off the relay turn off the output when the
temperature is below 20 degrees
Again when connected to the relay, start out
Setting example: If set to cooling mode, set temperature of 25 degrees, hysteresis is set to 5, then when
Measure the temperature below 25 degrees off the relay turn off the output when the temperature is
higher than or equal to 30 degrees
Again when connected to the relay, start out
refrigeration, heating mode settings: ◆
Press "SET" key and hold more than 3 seconds to enter the menu display, the screen appears "HC"
code, press "SET" key to display
Mode, press the "▲" or "▼" to adjust the display, C said cooling mode; H said heating mode.
◆ Return difference function:
Hysteresis setting limits the maximum interval between the engine off, this machine off on a minimum
interval between 1 ℃,
Up to 15 ℃.

settings:
Press "SET" key and hold more than 3 seconds to enter the menu display, with "▲" or "▼" button
appears on the screen raised to "D" on behalf of the
Code, press "SET" key to display the hysteresis set value, then "▲" or "▼" to adjust the parameters.
◆ Temperature calibration function:
When measuring the temperature and the standard deviation of temperature, the temperature correction
that allows the machine's measurement value and the standard temperature
Degree of consistency, corrected temperature before calibration temperature = value + correction value
(correction value can be positive, negative, and 0).
Temperature calibration settings: ◆
Press "SET" key and hold more than 3 seconds to enter the menu display, with "▲" or "▼" button
raised screen appears "CA"
Code, press "SET" key to display the correct temperature setting, press the "▲" or "▼" to adjust the
parameters.
For example: When we probe measured the temperature of 25 degrees, CA 25 degrees for the 0:00
show, CA show 26 to 1
Degree, CA display 24 degrees to -1. This feature is generally not measured directly in the probe using
the measured object.
For instance, we put the probe in a glass measuring cup out of the water temperature, because heat loss
my cup
We need to adjust the CA parameters, making the show the temperature of the temperature of matter
sorted out the same cup.
◆ Delay Protection:
In the cooling mode, the first power, when the measured value is higher than the difference between set
value + return immediately when the machine will not start
Refrigeration, the need to set the delay time after running the machine to start cooling; two adjacent
intervals is greater than the extension start cooling
Time when the machine immediately starts cooling, cooling the two adjacent intervals is less than the
delay time starts when the machine needs
The remaining delay time to start running the refrigeration. Delay time from stop instant starts.
Extension of the heating mode
The same as when the cooling mode.
Description: It is recommended that only cooling device using the compressor start delay, do not delay
start function
User set this parameter to 0
delayed protection settings: ◆
Press "SET" key and hold more than 3 seconds to enter the menu display, with "▲" or "▼" button
raised screen appears "PT"
Code, press "SET" key to display the time delay protection settings, press the "▲" or "▼" to adjust the
parameters.
◆ upper and lower functions:
HS and LS control setting limits set point temperature range, for example: HS is set to +15, LS is set to
-10,
Temperature control can only be adjusted between -10 and +15, when the control temperature to -10
when the press "▼" key to display
Value is still -10 and will not fall; when the control temperature to +15 when the press "▲" key to
display the value is still
+15 Will not rise. If set point is outside this range need, you must first change the value of the HS and
LS can be achieved.
Upper and lower limit settings: ◆
Press "SET" key and hold more than 3 seconds to enter the menu display, with "▲" or "▼" button
appears on the screen raised to "HS"
Or "LS" code, press "SET" button to display the upper or lower limits, then "▲" or "▼" to adjust
Parameters. HS said cap. LS said lower limit.
For example: the upper and lower limits are used to limit the range of temperature control can be set,
such as: LS is
10, HS 20, then press the SET button to adjust the temperature control on what can only be between 10
and 20
Change.

⑥ fault tips:
1) When the sensor is disconnected, the display shows --- and close the heating wire
2) When the sensor detects the temperature lower than -50 degrees, the display shows the LLL
3) When the sensor detects a temperature above 110 degrees, the display shows HHH
⑦ Caution:
◆ cooling, heat load must not exceed the output contact, or may cause machine damage and cause a
fire.
Disaster.
◆ a variety of connection wires and terminals connected to pressure well, otherwise, will cause the
machine reliability.
wiring, separate power supplies, relays, sensors, otherwise it will damage the machine. ◆
