①. The power cord and the wire of the fresh air valve are high-voltage, while the communication cord and connection
wire of the wired controller are low-voltage. They should run separately against electromagnetic interference.
②. The high-voltage and low-voltage lines should pass through the rubber rings at different electric box covers.
③. Do not bundle the connection wire of the wired controller and the communication cord together, or arrange them in
parallel, otherwise improper operation would occur.
