The fresh air controller is an important part of the fresh air system and is responsible for controlling the operation of the fresh air system. Before installing the fresh air controller, it is crucial to carry out sufficient preparation work, which can ensure the smooth installation process and guarantee the normal operation of the fresh air system. Here is the work that needs to be done before installing the fresh air controller:

1. System inspection and evaluation:

● Ensure that the components of the fresh air system are complete and check their status.

● Clean and maintain the various parts in the system, such as air ducts, supply air outlets, and return air outlets.

● Check the smoothness of the air duct, ensure that the fan operates normally, the filter is clean, and the sensors and connection lines are intact.

2. Circuit planning and preparation:

● Plan the circuit connection path and layout.

● Ensure safe laying of wires and stability of connections.

● Confirm the power supply and distribution box location, complying with safety standards.

3. Debugging and testing:

● Connect and set up the controller according to the manufacturer's guidelines.

● Start the system for functional testing to ensure accurate sensing of environmental parameters.

● Conduct operational and simulation tests to ensure the system responds normally to various conditions.

4. Preparation of operating guides and training:

● Create detailed operating guides, including basic information, operating steps, and troubleshooting methods.

● Train relevant personnel to familiarize them with the use of the controller and precautions.

In the process of performing these preparation tasks, ensure a careful and meticulous check of every detail, as these steps are vital for the stable operation of the fresh air system. Only by ensuring that these tasks are completed before installation can the indoor air quality be effectively improved and the smooth operation of the system be guaranteed.
