DC 12V W1209 Digital Cool/Heat Temp Thermostat Thermometer Temperature Controller On/Off Switch -50-110C

100% complete machine patch, wave soldering, stable performance, good consistency.
Embedded CPU chip (MCU), more intelligent, lower power consumption.
Automatic power set memory (MCU built-in EEPROM memory unit).
Control accuracy of 0.1 degrees Celsius. Have been tested for stability, consistency and reliability.
Tips: – long press set to get menu, starts at P0 – press +/- to get next P-parameter – press set to choose that parameter – press +/- to select the value you want for that parameter – press set to accept it – long press +/- = reset to default – power-out does reset to default – default temp set is 34.5C
