Precaution of installingthe wire controller
1. This manual provides the installation method of wired
controller. Please refer to the wiring diagram of this installation
manual to connect the wire controller with indoor unit.
2. The wired controller works in low voltage loop circuit.
Forbid to directly contact the cable of high voltage above,
like 115V,220V,380V, and don’t wire this kind of wire in the
said loop; wiring clearance between congured tubes should
be at the range of 300~500mm or above.
3. The Shielded wire of the wired controller must be grounded
rmly.
4. Upon nish the wire controller connection, do not employed
