Installation and Debugging                                               
Installation Methods Fix detector by means of two screw s hanging methods, and distance 
between screws see (right figure).
1. Realization, installatio n, wiring and power distribution of a system only 
using two-unit swit chover function are much  more easier, after finishing 
installation of two units,  connect detector to the remote control interface 
of the air conditioner computer board,  set detector as two-unit switchover 
working mode and set two-unit switchover time as required. 
2.  It must form a complete set of documents (project la yout for group control network, installation and 
construction records for group control  network, debugging records for group control net, maintenance 
and repair records for group control network) for  group control network of Haier commercial air 
conditioner long distan ce system (hereinafter for short as: group c ontrol network) from layout design, 
installation, debugging to after service, and file all for future refere\
nce. 
3.  Layout design of group  control net woek shall be finished in advance, including: (1) compositions of 
group control network system and qu antities controlled; (2) selection type of air conditioner, 
installation place, power distribution and wiring manner and  connection to detector; (3) installation 
place of detector, allocation of unit address  code, power distribution and wiring manner and 
connection to group control bus; (4) in stallation and wiring of group control bus, length limitation of 
bus, resistance matching of two en ds of bus, and single point earth of bus shielding layer; (5) 
installation place of central  controller, allocation of unit address  code, power distribution and wiring 
manner. 
4.  Principles of layout design of group control net : (1) detector is essential part, to keep proper 
responding speed and co mmunication reliability, d etector quantities carried by  one central controller 
shall not more than 64; (2) air conditioner must  be a net air conditioner, installation must strictly 
follow the installation and operat ion instructions shipped with the unit, and confirm that power 
blackout compensation fun ction of local air conditioner has bee n cancelled when debugging; (3) 
suggest that do not use two-unit switchover function of detector in the case of high load, i.e. suggest 
that do not use one detector to load two air  conditioners when detector forming group control net, 
otherwise temperature difference control may be affected. If it is necessary to install two-unit 
switchover function for group cont rol net, air conditioners with same type and half installation 
distance of that of normal installation are required; (4) installation place of detector shall not too far 
away from air conditioner, not ex ceed the wiring length; (5) unit address code of detector shall be 
strictly allocated in a seq uence from small one to big one,  and set continuous unit number; (6) for 
power distribution of detector, the power distributi on line and communication line shall not be too 
close from each other or in the same wiring chan nel, and no other special requirements; (7) for 
connection between detector and  group control bus, not allowed to connect branch line from the 
group control bus; (8) shie lding line of communication line betwee n detector and air conditioner and 
the shielding line of commu nication bus between detector and central controller shall be shorted; (9) 
wiring and power distribution line of the group control bus  shall not be too close from each other or 
in the same wiring channel, and others may refer  to wiring requirements of building autocontrol 
system;    (10) limit the total leng th of group control bus to 1000 meters; (11) at both ends between 
Bus A and Bus B connect a metallic membrane precision  resistance of 100 or 120 ohm respectively; if 
needed (12) single point earth for bus shielding l ine, suggest to be arranged in the middle of 
communication bus, close to central controller;

Installation and Debugging                                                 
(13) in principle, installation place of central controller shall be  arranged in the middle of 
communication bus, close to shielding earth  line of communication bus; (14) unit address codes of 
central controller adopt the defaul t settings; (15) central controller has its own power distribution line, 
the power distribution line and communicati on line shall not be too close from each other or in the 
same wiring channel, and no other special requirements. 
5.  Installation and construction of  wiring of group control network shall be processed together with 
installation and debugging of net air conditioner, pay attention to commissioning before installation. 
6.  Connection between detector  and air conditioner: detector working  mode and unit address code shall 
be strictly set according to planned layout; detector  makes wire communication with at most two air 
conditioners (A, B) through 4-poles screw-fixing terminal at air conditioner interface (A
+,A-, B+, B-);
connection between detect or and air conditioner use un iform wiring; use uniform wiring for 
connection between detector and air conditioner,  one plug in type terminal of wiring connected to 
Remote control interface on the  computer board of air conditioner, and cores of another terminal 
respectively connected to A
+ and A- (B+ and B-); connection has polarity, and generally white wire 
connected to A
+/B+ and black/red wire connected to A-/B-; if detector cannot  work normally when 
debugging, then can check and remove malfunctio n by changing positive and negative polarity. 
During debugging also can judge wheth er communication interface to air conditioner is normal 
according to the running status indicated by operation indicator (green\
 LED). 
7.  Connect detector and communication bus after  finish the wiring of communication bus: connect 
several detectors to communicati on bus in parallel, all terminal port A (including central controller) 
on one bus, and all terminal port B (including centra l controller) on another bus, at both ends of the 
communication bus - A terminal port line and B terminal port line shall paralleling connect a metal 
membrane precision resistance of 100 or 120 ohm  respectively if needed. Earth one point of the 
shielding line of communication bus, which is at th e middle position of the communication bus, and 
the total length of communication bus shall be limited within 1000m. 
8.  Connect central controller and communication bu s after finish installation and connection of detector: 
central controller is connected  to communication bus through the  2-post screw-fixing terminal (A and 
B) of interface RS-485, locating  in the middle of the communication bus, with position close to the 
earth point of the shielding line of communication bus. 
9.  Power on and debugging : after power on, central controller periodically monitors the detector and air 
conditioner groups on the communication bus, a nd after inquiring for a period of time the unit 
number shall display as expected, check and debug if having any difference. 
10.  Set the dialing switch of detec tor: (1) there is a 8-bit (18) dialing switch inside the detector, OFF 
means 0 and ON means 1; (2) the eighth bit used for s etting single unit working mode or two-unit 
switchover working mode, OFF m eans single unit and ON means two-un it; (3) the lower seven bits 
(from the seventh to the first bit) have up to 128 selections when forming group control net, which are 
used for setting unit address code,  see the table below for detail setting check list; (4) the lower seven 
bits have up to 128 selections when forming group  control net and using two-unit switchover function, 
which are used for setting unit address code, see the ta ble below for detail setting check list, and the 
default two-unit switchover time is 24 hrs; (5) the lower seven bits have up to 128 selections when not 
forming group control net, wh ich are used for setting two-unit sw itchover time, see the table below 
for detail setting check list.
