than the actual water temperature to cool.
3.After setting the temperature, the LCD shows the current water temperature, and the
chiller will select cool or heat mode automatically after comparing the set temperature and
actual water temperature. If in cool mode, the green indicator blinks in “delayed start” state,
after a 3 minutes’ delay, the chiller starts chilling, and the green indicator becomes solid. If
in heat mode, the heater works without delay and the red indicator turns on (Note: heater
not included, it requires the user to insert a heater with a two-pin flat plug).
4.When the chiller works in cool mode, the green indicator turns on. When the water
temperature drops to the pre-set temperature, the chiller stops working. If the water
temperature rises to meet the starting condition (temperature difference is 2℉), the chiller
enters a 3-minute delay and then starts working automatically. By repeating in this way, the
chiller keeps the water temperature stay between pre-set temperature and the temperature
+ 2℉. See the Fig. 5.
5.When the chiller works in heat mode, the red indicator turns on. When the water
temperature rises to the pre-set temperature, the heater stops working. If the water
temperature drops to meet the starting condition (temperature difference is 2℉), the heater
works again. By repeating in this way, the chiller keeps the water temperature stay
between pre-set temperature and the temperature - 2℉. See the Fig. 6.
