When turned on, EcoSimmer will display two numbers. Read them vertically as the temperature of its contents in Celsius. For example: when EcoSimmer displays “93”, its contents are at 93ᵒC (199ᵒF).
Bonus: Generally, the numbers in Celsius can be interpreted as the % progress towards boiling as well.
When a boil is reached, the numbers flash rapidly, indicating that heating has stopped. EcoSimmer will continue to flash until unplugged.
