c.
In the “Setup” mode, if the user does not press any button within 15 seconds, then the temperature controller will
exit the mode, save the parameter, and return to normal mode. The display will show the current temperature.
5.
Displaying the highest and lowest temperature: when the temperature arrives at the set temperature, start to make record
of the highest or lowest temperature ever reached. Please press Log button to see the highest or lowest temperature ever
reached, if keep pressing Log button for 5 seconds, the record will become the temperature of cool water and make
record again.
6.
Quick Setting: The operator can amend the set temperature(ts) with few simple steps, as follows:
1)
Press ▼ for 3 seconds to enter setting mode, at this moment the set light will glow.

“UA” The temperature of cool water exceeds the limited temperature.
b)
“LA” The temperature is below the lowest temperature.
c)
Warning output:(output is on one second/off one second)
d)
When the warning delay time arrives, the warning output will turn on. The operator can press ▼ to mute the
