Abstract of Funct ion

Remote control detector (heveunder as: detector) is the necessary part and users optional part of Haier

commercial air conditioner remote monitor and control system. Net air conditioner (heveunder as: air

conditioner or remote) means a air conditioner with remote control interface on indoor computer board,

onlu which could combine with parts such as detector and central controller to form remote or detector

interface monitor and control system.

Detector is a key part of Haier commercial air conditioner remote monitor and control system, used for

transferring standard digital interface to realize communication between bus code and sub-address. It is

connected directly to air conditioner to realize local operation and collection of control information and

working information of air conditioner. Together with air conditioner central controller (hereunder as:

central controller) and air conditioner, form the Haier commercial air conditioner remote monitor and

control system group control function network to realize data exchange and monitoring. Abstract

description as follows:

A. Communication Function

1. Communication with air conditioner

Perform wire communication with at most two air conditioners through 4-poles screw-fixing terminal,

and can realize two-unit switchover function when connected to two air conditioners, which control

operation status of air conditioner by different ways according to inner control or inquiry demand of

detector, and check working information and malfunction information of air conditioner at the same

time.

2. Communication with central controller (another optional accessory, a control component of Haiercommercial air conditioner remote monitor and control system)

Realize communication with central controller through RS-485 interface bus. According to the

components number set by internal dialing switch, receive commands from central controller, form

internal control or enquiry request of detector and answer reception status and working information

and malfunction information of air conditioner.

B. Power Failure Resume

To reduce the impaction to power network when air conditioners simultaneously start, detector have

power blackout compensation function to replace the power blackout compensation function of local

air conditioner when use group control net; When power restored after blackout, air conditioner can

automatically restart with different delay according to basic running status before power blackout.

C. Two-unit Switchover Function

To increase operation reliability of air conditioner, detector is equipped with two-unit switchover

function, and the internal dialing switch of detector set single-unit operation mode or two-unit

switchover mode. When select single unit mode, detector controls unit A according to commands

from previous unit. When select two-unit mode, unit A and unit B have absolutely equal position in

realizing two-unit switchover function.

Abstract of Funct ion

Realization of two-unit switchover function: in normal operation status, one air conditioner is started

to operate under the control of detector and another one stops to wait, when its time for switchoverthe detector wakens the waiting air conditioner and recalculates time, and the previous running one

will continue to operate and automatically stops to wait half hour later. If any of air conditioner fails

to function, switchover timing is temporally stopped, the detector is automatically controlled to waken

another air conditioner and after that stop the malfunction one to wait status. The detector will

forward transfer the malfunction information when inquiring and automatically restore two-unit

switchover function after malfunction is removed. If air conditioner cannot reach the setting

temperature after a period of running, that is over-load, switchover timing will be temporally stopped,

the detector is automatically controlled to waken another air conditioner and two units operate

together until the setting temperature is obtained, now automatically stop the latter started conditioner

and restore two-unit switchover function automatically.

D. Unit Number Setting Function

There is a 8-bit dialing switch inside the detector, the highest order is D8 used for setting single unit

operation mode or two-unit switchover operation mode; lower seven bits (D7, D6, D5, D4, D3, D2

and D1) are used for setting unit number (group control network) or two-unit switchover time

(two-unit switchover).

E. Working Status Display Function

Detector indicators are divided into power indicator (red LED) and operation indicator (green LED):the operation indicator has the function of displaying operation status, and the power indicator lights if

power is normal after power on; lit operation indicator means that detector works normally, and

flashed operation indicator shows operation status of detector and distinguishes the meaning of

different status by flashing times.

F. Time Delay Control Function

When forming central control network through RS-485 bus, detector sets start delay function to

reduce impaction to power network because of simultaneous control and operation of air conditioners,

and delay time is created by detector randomly and automatically.

G. Detector can only be used for some of Haier Commercail indoor type , for example: Free Multi Wall

mounted type, Console type etc. Detector is necessary for Weekly timer or central controller

installation for this types. But Duct type, Cassette type, Convertible type couldnt use detector., they

can directly be connected with weekly timer or central controller.
