*1. TDET: set value for detection temperature, TDH: actual detection temperature for higher temperature,
TDL: actual detection temperature for lower temperature
Either of two detection temperatures (TDH, TDL), an accuracy of ±2.5°C is set only for the one that user specifies a higher
accuracy than the other (TDH, TDL).
*2. ΔTDET: set value for detection temperature for higher temperature − set value for detection temperature for lower
temperature
ΔTD: actual difference of detection temperature
Set two points of detection temperature so that the difference of detection temperature (ΔTDET) is in 0°C to 65°C. Users are
able to set ΔTDET in 0°C, 5°C, 10°C … 60°C, 65°C.
*3. Users are able to select the hysteresis temperature in −5°C, −2°C, +2°C, or +5°C.
