Abstract
The invention relates to a backup running processing method and system of commercial water heaters. The method includes the following steps that firstly, whether an environmental temperature sensor of a master machine has a fault or not is judged; if yes, the master machine stops running, and the second step is executed; and if not, the system is started and shut down according to the environmental temperature of the master machine, and operation ends; secondly, whether environmental temperature sensors of all slave machines have faults or not is judged; if yes, all the water heaters stop running, and operation ends; and if not, the system is started and shut down according to the environmental temperature of the slave machines, and operation ends. The system is started and shut down according to whether the environmental temperature sensors of the slave machines have faults or not and the environmental temperature of the slave machines, and influences caused by the fault of the environmental temperature sensor of the master machine are reduced. Meanwhile, the water heaters in abnormal conditions are protected, the normal water heaters are fully utilized, the using rate of the parallel system of the water heaters is increased, and more convenience is brought to users.
