Installation and Debugging
(12) The bus shielded wire is single-point grounded. It is recommended to arrange it
in the middle part of the bus and near central controller or weekly timer; (13) The
installation position of central controller or (and) weekly timer arrange in the middle
part of the bus in principle and near the communication bus shielded grounding wire;
(14) The address unit number of central controller is set as default; the address unit
number of weekly timer is set as default; the central controller unit No. can't the same
as that of the weekly timer. (15) The central controller is in its own separate wiring
circuit; the wiring circuit and the communication circuit shall not be too close or pass
the same channel; no other special requirements; (16) The weekly timer uses 12VDC
power supply, which can be directly connected from the neighboring detector or
connected with other DC12V power supply; (17) Weekly timer can cooperatively use
together with central controller as a controller, or use weekly timer separately as the
only controller.
4. The wiring and installation of group control network will be done synchronously
together with the installation and debugging of network air conditioner. Please perform
test run before installation.
5. Connection of detector and air conditioner: The working mode and address unit
number of detector shall be performed strictly in line with the planned programming;
detector executes wire communication with at most two sets of air conditioners by the
air conditioner interface 4-core screw fixed terminals (A+, A-, B+, B-); the connection
of detector and air conditioner shall use the same wire; the inserted terminal at one
end of the wire is connected with the remote control interface on the air conditioner
PCB, the core wire at the other end of the wire is respectively connected with A+, A-
(B+, B-); the connection has polarity: generally the white wire connects A+/B+, black
wire/red wire connects A-/B-; in debugging, if the detector cannot work normally, it
can be checked by exchange between + pole and + pole. In powered on debugging, it
can also use the operation state displayed by the operation light (green LBD) to determine
whether the air conditioner communication interface is normal.
