4 Control Function Instruction
When the controller works normally, the PV shows the
measured temperature, meantime the SV screen shows the
temperature setting value, and automatically recognizes and
converts for the heating or cooling working mode , in which
WORK1 is the heating output, furthermore the red led is the
WORK1 heating output status indicator;WORK2 is cooling
output, furthermore the green led is WORK2 cooling output
status indicator.
4.1 Instructions for Setting Temperature Control (TS,HD,CD）
4.1.1 Normal Temperature Control：
When the measured temperature PV ≤ TS(Temperature Setting
Value) – HD(Heating difference value),the controller will enter
the heating state, the red led is on, WORK1 output works.
When the measured temperature PV ≥ TS(Temperature Setting
Value), the red led is off and the WORK1 output turns off.
When the measured temperature PV ≥ TS(Temperature Setting
Value) + CD(Cooling difference value), the controller will enter
the cooling state, the green led is on, WORK2 output works;
the green led flashes, indicating that the cooling device is in
the state of the Compressor delay protection. When
PV(measured temperature) ≤ TS(temperature setting value),
H
C
P
.2
10
the green led is off and the WORK2 output turns off.
For example, setting TS=25.0°C, CD=2.0°C, HD=3.0°C, when
the measured temperature value ≤ 22°C (TS-HD), the
controller will enter the heating state; when the measured
temperature value ≥ 25°C, the heating will stop; when the
measured temperature value ≥27.0°C(TS+CD),the controller
enter the cooling state; when measured temperature value ≤
25.0°C, cooling will stop.
4.1.2 Special Temperature Control
There is no need to judge the difference value in heating or
cooling when power on or exiting the setting state, it directly
compare with TS(temperature setting value).
For example: When power on or exiting the setting state,
TS=25.0°C, CD=2.0°C, HD=3.0°C. If PV( measured temperature
value) >25.0°C, it enters the cooling state. When PV(measured
temperature value) ≤25.0°C, the cooling stops. Then return to
normal temperature control. When PV(measured temperature
value) <25.0 °C, it enter the heating state, when PV(measured
temperature value) ≥ 25.0 °C, heating stops, and then return to
normal temperature control.
4.2 Alarm High / Low Temperature Limit Settings(AH,AL）
When measured temperature ≥ AH, high temperature limit
alarm, then will turn off heating and cooling output, PV shows
alternate AH with current temperature, buzzer will “bi-bi-Biii”
alarm, until the temperature <AH, buzzer off and return to
normal display and control. Or press any button to turn the
buzzer alarm off only.
When measured temperature ≤ AL, low temperature limit
alarm, then will turn off heating and cooling output, PV shows
alternate AL with current temperature, buzzer will “bi-bi-Biii”
alarm, until the temperature >AL, buzzer off and return to
normal display and control. Or press any button to turn the
buzzer alarm off only.
11
4.3 Compressor Delay Time（PT）
In the cooling mode, when the power is turned on for the first
time, PV(measured temperature value) ≥ TS(Temperature
setting value) + CD(Cooling difference value), it will not start
cooling immediately, but waiting for a delay time(PT).
When two adjacent of cooling starting intervals are greater
than the delay time, it will immediately start cooling; When two
adjacent of cooling starting intervals are less than the delay
time, it needs to operate the remaining delay time to start the
cooling.
Delay time will start counting from the cooling output off.
4.4 Temperature Calibration(CA）
When the measured temperature deviates from the standard
temperature, the temperature calibration function can be used
to make the measured value of the instrument consistent with
the standard value. The calibrated temperature=the measured
temperature + the calibration value.
4.5 Fahrenheit or Celsius Settings (CF）
The users can set the display unit to Fahrenheit or Celsius
according to their habits. The default temperature is
Fahrenheit. If you need to display the unit in Celsius, then set
the CF to C. Please note that when the CF changes state, all
setting values are restored to the default setting and the
buzzer gives a short beeping prompt.
4.6 Timer Setting (TR）
TR
is the parameter for whether the timer function is enabled.
0 is off and 1 or 2 is on. If user set TR=1 or 2,please see

4. Control Function Instruction
When the controller works normally, the PV shows the
measured temperature, meantime the SV screen shows the
temperature setting value, and automatically recognizes and
converts for the heating or cooling working mode , in which
WORK1 is the heating output, furthermore the red led is the
WORK1 heating output status indicator;WORK2 is cooling
output, furthermore the green led is WORK2 cooling output
status indicator.
4.1 Instructions for Setting Temperature Control
（TS,HD,CD,S01~S12）
4.1.1 TR=0, Temperature Control Mode
4.1.1.1 Normal Temperature Control
When the measured temperature PV ≤ TS(Temperature Setting
Value) – HD(Heating difference value),the controller will enter
the heating state, the red led is on, WORK1 output works.
When the measured temperature PV ≥ TS(Temperature Setting
Value), the red led is off and the WORK1 output turns off.
When the measured temperature PV ≥ TS(Temperature Setting
Value) + CD(Cooling difference value), the controller will enter
the cooling state, the green led is on, WORK2 output works;
the green led flashes, indicating that the cooling device is in
the state of the compressor delay protection. When
PV(measured temperature) ≤ TS(temperature setting value),
the green led is off and the WORK2 output turns off.
20
For example, setting TS=25.0°C, CD=2.0°C, HD=3.0°C, when
the measured temperature value ≤ 22°C (TS-HD), the
controller will enter the heating state; when the measured
temperature value ≥ 25°C, the heating will stop; when the
measured temperature value ≥27.0°C(TS+CD),the controller
enter the cooling state; when measured temperature value ≤
25.0°C, cooling will stop;
4.1.1.2 Special Temperature Control
When TR=0, there is no need to judge the difference value in
heating or cooling when power on or exiting the setting state,
it directly compare with TS(temperature setting value).
For example: When power on or exiting the setting state,
TS=25.0°C, CD=2.0°C, HD=3.0°C. If PV( measured temperature
value) >25.0°C, it enters the cooling state. When PV(measured
temperature value) ≤25.0°C, the cooling stops. Then return to
normal temperature control. When PV(measured temperature
value) <25.0 °C, it enter the heating state, when PV(measured
temperature value) ≥ 25.0 °C, heating stops, and then return to
normal temperature control.
4.1.2 When TR=1 or 2, Timer Mode
The TS(temperature setting value) will be invalid. The
controller will execute commands according to the setting
values of S01~S12, the setting value of H01~H12, and the
setting value of U01~U12.
About how to set the time and control temperature, please
refer to 6.6
4.2 Alarm High / Low Temperature Limit Settings (AH,AL）
When measured temperature ≥ AH, high temperature limit
alarm, PV shows alternate AH with current temperature,
buzzer will “bi-bi-Biii” alarm, until the temperature <AH, buzzer
off and return to normal display and control. Or press any
button to turn the buzzer alarm off only.
When measured temperature ≤ AL, low temperature limit
alarm, PV shows alternate AL with current temperature, buzzer
will “bi-bi-Biii” alarm, until the temperature >AL, buzzer off and
21
return to normal display and control. Or press any button to
turn the buzzer alarm off only.
4.3 Compressor Delay Time(PT）
In the cooling mode, when the power is turned on for the first
time, PV(measured temperature value) ≥ TS(Temperature
setting value) + CD(Cooling difference value), it will not start
cooling immediately, but waiting for a delay time(PT).
When two adjacent of cooling starting intervals are greater
than the delay time, it will immediately start cooling; When two
adjacent of cooling starting intervals are less than the delay
time, it needs to operate the remaining delay time to start the
cooling.
Delay time will start counting from the cooling output off.
4.4 Temperature Calibration(CA）
When the measured temperature deviates from the standard
temperature, the temperature calibration function can be used
to make the measured value of the instrument consistent with
the standard value. The calibrated temperature=the measured
temperature + the calibration value.
4.5 Fahrenheit or Celsius Settings (CF）
The users can set the display unit to Fahrenheit or Celsius
according to their habits. The default temperature is
Fahrenheit. If you need to display the unit in Celsius, then set
the CF to C. Please note that when the CF changes state, all
setting values are restored to the default setting and the
buzzer gives a short beeping prompt.
4.6 Time-Temperature Setting Values Execution Cycle
Times MD and Time-Temperature Parameter Settings
(TR,UT,STT,SST,S01~S12,H01~H12,U01~U12）
4.6.1 MD
is the execution times of the time-temperature
setting value. From the SST setting value to the last stage
setting value of STT, it is a cycle. If MD=0 represents an
infinite loop, MD=1~999 represents the specific times of cycle
execution. The default value of MD is 1. Under the condition of
MD=1~999, after the corresponding execution cycles is
22
completed, the detailed status is described in 6.4.6.8.
4.6.2 TR is the parameter for whether the timer function is
enabled. 0 is off and 1 or 2 is on.
4.6.2.1 TR=0,Temperature Control Mode The timer function
will not start, all the setting parameters after the parameter TR
will not shows in the menu, and there is no need to set.
4.6.2.2 TR=1 Continuous Timer Mode & TR=2 Target Timer
Mode
The user is required to set the time and corresponding
temperature control parameters, at this time, TS(temperature
setting value) will be invalid, the system will control according
to the temperature of the time period.
Regarding the difference between TR=1(Continuous Timer
Mode) and TR=2(Target Timer Mode), the following table
illustrates their differences in details.

4.6.3 UT is a time unit setting parameter, and the user can set
the time unit to days, hours or minutes as required；
4.6.4 STT is the setting stages of the time – temperature
period. Users can set different time periods to control different
temperature according to their needs. At most 12 time periods
can be set to control 12 different temperature.
4.6.5 SST is the beginning stage of time - temperature
period. Users can select which stage to start control
according to their own requirements.
4.6.6 S01~S12 are temperature setting parameters. When
TR=1 or 2, the setting value of ST1~ST12 will replace the TS
value as the condition parameter of temperature control;
4.6.7 H01~H12 are duration parameters, and the current
