In the past, many equipment parts of swimming pool water treatment and heating cycle were purchased in the market one by one and then shipped to the site for assembly and integration. Due to the differences in the types of equipment interfaces and the restrictions on the construction conditions of the machine room, there are high requirements on the installation technology of the construction personnel and the clinical construction procurement ability of the parts procurement personnel. During the maintenance process, it is often necessary to manually switch the relevant valves and then operate the control system, which increases the maintenance difficulty. With the increase of labor costs, we urgently need a one-time procurement, easy to install, easy to operate, easy to maintain the high quality of the factory system products.
