P1 – Setting temperature in 0.5 ºC steps
This function is used to dene whether setting temperature is adjusted in 0.5 ºC steps (when set to “00”) or in 1 ºC steps
(when set to “01”).
This setting also determines whether the resolution of temperature di󰀨erential of the thermistor is 0.5 ºC (when set to
“00”) or 1 ºC (when set to “01”) enabling more precise setting control.
