Abstract

The invention discloses a control method, device and system. The method comprises the steps that a wire controller monitors communication disconnection information, an internal unit of a hot water unit starts a heat source according to the communication disconnection information so as to perform heating or water heating. By means of the control method, device and system, an internal unit mainboard can start an emergency mode to operate under the situation that an external unit mainboard is powered off for maintenance or a communication fault occurs, and accordingly the basic heating or water heating demand of a user is met.

Description

technical field [0001] The present invention relates to the field of household appliances, in particular to a control method, device and system. Background technique [0002] The current multi-functional hot water unit can use RS-485 for communication. Generally, the main board of the external unit is set as the upper computer, and the wire controller and the main board of the internal unit are set as the lower computer. The interaction process between the upper computer and the lower computer is as follows: Initiated by the main board, if the main board of the external unit is powered off, the entire control system will have a communication failure and cannot control the load. When the emergency mode is set on the wire controller, if the main board of the outdoor unit fails and shuts down, the main board of the indoor unit can enter and start the emergency mode within a certain period of time, so as to maintain the basic heating or hot water demand of the user. However, in...
