The on-off controller in the prior art is usually multiple separate components, and cannot form an integrated device / equipment, leading to more complicated operation when applied on site (such as when the heating system is constructed during the home decoration process), and the centralized control cannot be realized, leading to difficulty in realizing the requirement of heating and temperature control in different areas. In summary, a new type of on-off controller needs to be developed and designed to solve the foregoing technical problems. UTILITY MODEL CONTENT
