consecutively:
Operation
Set set-point (SP). Factory default set is 35.0℃
Keep〖S〗depressed for 3 seconds to enter into temperature setting status:
blinks, the SP value displays.
Press〖▲〗or〖▼〗to set the value.
Press〖S〗to save and exit the status.
The status will exit, and the value will be saved, when there is no key operation for 30 seconds.
