No. Cause Solution
1 The network is busy. Connection via an intra-company LAN may slow the Web screen display due
to a busy network. Use the system during off-peak hours of network use, or
use a dedicated network to connect a PC with the controller.
If a 10 BASE switching HUB is used, replace it with a 100 BASE switching
HUB.
2 PC performance has degraded. If some application programs are operating other than the browser, the PC
performance may degrade. Close the operating applications other than the
browser, and check if the PC performance improves.
3 Trouble due to the browser. The supported browsers are Internet Explorer 8.0, 9.0 and Firefox 7.0, 8.0. If
a browser other than these browsers is used, the contents may not be
displayed properly. Use one of the supported browsers to see the contents.
4 Other users are also accessing the controller. If other users are performing schedule setting or other operation, the display
switching may slow down. Wait for a while, and access to the controller again.
5 The controller is writing a file. The controller regularly writes a file for electricity distribution. The display
may slow down during the writing process.
6 Effect of firewall software. Turn off the firewall software and check the WEB screen display.
7 It may take some time (more than 3 minutes) to display
the web screen depending on the combination of the
connected HUB.
Change the HUB, and check it again.
8 Communication may be slow depending on the network
environment.
Calibrate the value of TimeWait.dat setting file for network communication.
No. Cause Solution
1 The controller performance has degraded. If the controller is accessed from a browser while the controller internal
processing is in progress, the controller performance degrades. To prioritize
controller internal processing (writing a file or giving instruction to an air
conditioner), the system once stops the access from the browser. Log on
again.
