2. Indoor unit Central Control System
2.1) Network Interface Module
Suit to indoor unit which PCB hasn’t network function.
(1) Basic Requirements
•
Applicable Power Voltage Range: Input Voltage 220VAC±10%.
•
AC Input Power Frequency: 50Hz/60Hz.
•
Working Ambient Temp: -10
o
C
~
+43
o
C
•
Working Ambient Humidity: RH40%~RH90%.
(2) Function Description of NIM
NIM means network interface monitor, it is integrated in the indoor PCB.
The CCM, Electric Control of air-conditioners, PC and Communication Wire together
compose the network control system of air-conditioners. The CCM can connect up to max 64
indoor units, which together compose one LAN (Local Area Network), thus the CCM can central
control to all air-conditioners in the LAN, including sending every kind of control order to every
air-conditioner and setting running states of every air-conditioner. And the control signal of
CCM can arrive to the farthest 1200 meters, which can meet various control requirements for
customers.
(3) AUTORESTART function
It’s a standard function of digital scroll system.
♦
System will not carry out the AUTORESTART function for the first time power on.
♦
During operating or stand-by, if power failure occurs, previous settings will restore after
supplying power again.
♦
The following settings can be restored after power failure occurs: ON/OFF, MODE, FAN
SPEED, and TEMP. LOCK by CCM and so on. And the following can’t be remembered:
ECONOMIC, TIMER ON, TIMER OFF, SLAVE Function and so on.
