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.

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
