1. Before installation, several important factors must be considered. For example, the connection between gas pipeline and wall-hung boiler should conform to the relevant specifications of gas pipeline; The connection between the hydraulic pipeline and the wall-hung boiler shall conform to the relevant specifications of the hydraulic pipeline; The connection between the electrical part and the wall-hung boiler shall conform to the relevant electrical specifications.

2. Turn on the power switch on the operation panel of the wall-hung boiler and turn on the power. Then press the mode key, and the sun symbol will be displayed for the first time, representing the summer mode (suitable for bathing in spring, summer and autumn or standby in winter). Click it again, and a snowflake symbol will appear, representing the heating mode in winter, and heating and bathing can be automatically switched.

3. When adjusting the outlet water temperature (or backwater temperature), in principle, the temperature is required to be lower when the weather is warmer and higher when the weather is cold. The initial temperature difference will also change with the seasons. You can set a larger temperature difference in warm weather and a smaller temperature difference in cold weather.

4. Large waterway system and long pipeline will lead to poor water circulation. In order to avoid frequent shutdown and reduce the outlet water temperature, the synchronous circulating water pump on the pipeline is added.
