confirm and automatically enter the next parameter setting, until the system
finally withdraws from the set conditions and returns to the conditions of the
previous clock. The set order of parameter in specific modes is as follows:
Solar energy heating mode:
Indicating clock condition---to set heating temperature in fixing temperature-
--indicating clock condition. For example: temperature difference value
setting of water pump running: to press the setting key to enter the setting
condition of temperature difference of water pump running. The indication
board indicates the present set value (the first place on the left of the clock
number tube indicates L, and the following two places indicate the tacitly
