6.4.1.1 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, HEATING
output works. When the measured
temperature PV ≥ TS(Temperature Settin
Value), the red led is off and the HEATING
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, COOING 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 COOING
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 state;
when the measured temperature value
≥ 25°C, the heating will stop; when the
