| Name | Sensory type | Range(℃) | Accuracy | Remark |
| TH570N | Thermistor | －50.0~150.0 | ±1.5℃ | Max ± 3.5℃ temperature deviation may be happen (± 1.5℃ sensor deviation & ± 2℃ controller deviation) |

Control method for temperature
■ Heating/cooling control selection
Connection diagram
■ Cooling control(ON/OFF)
• PV 〉SV → Main output relay “ON” / PV〈 SV → Main output relay “OFF”
■ Heating control(ON/OFF)
• PV 〉SV → Main output relay “OFF” / PV〈 SV → Main output relay “ON”
Proportional control
- Manipulated variable (output size) of set value operates by proportioning to deviation and this is known as proportional control. Also variation range of manipulated variable from 0 ~ 100 % is known as the proportional band. Therefore, when proportional band is less than the current temperature, the manipulated variable becomes 100 % and when PB is more than the current temperature, the manipulated variable becomes 0 % and when set value and current temperature becomes same, the manipulated variable becomes 50 %.
Delay timer set
• Press 
key continuously for 3 sec, and then, press key until getting “
“. change a set point by / key, and preservation it by key.
■ Operating description by delay-timer
※ In case of Delay Time=0, Relay is immediately ON when output signal is generating. In case of delay time=5, Relay is ON after 5 sec.
when output signal is generating. In the interval of 5 sec, the output indicator is flickering during delay timer operation. After the delay time, the output indicator lights as the relay is on.
Auxiliary output(Timer-mode) set and operating description
- It is possible to use timer-mode as defrosting function in case of freezer.
- When using MOC ‘1’, main output will be OFF automatically as timer is ON.
- If using MOC function, you can effectively use timer output as a defrosting function.
※ When auxiliary output is timer mode, time unit is selective between “sec” or “min”.
Set mode for equipment provider
