Max. 10 units

G-50A Ver. 2.50 or higher

Indoor unit

Max. 50 units/G-50A

Max. 500 units (including all IC, KIC, AIC, LC, and FU)

[Symbol] IC: Indoor unit, LC: LOSSNAY, FU: OA processing unit, AIC: “A” controller, KIC: “K” controller

Checking the G-50A version

Check the centralized controller G-50A version. Update if it is not the applicable version.

Method 1: Using the initialization tool

The version can be monitored from the Basic Setting window. Method 2: Using the G-50A main unit

Press the [↑][↓] buttons for two seconds or longer to open the Initialization Mode Menu window. Then［ ］button to open the second menu window. The version will appear at the lower right.

*If the integrated centralized control software TG-2000A has already been installed, the G-50A version can be confirmed with Operation Manual TG-2000A.

Updating the G-50A

Update by the Update Program CD (for G-50A).

(2)Correspondence at the time of abnormalities

・For the period under reboot of PC, failure of G-50A, etc., neither each control nor a function may operate normally.

(3)Operation at the time of a power failure

・If a power failure occurs, the power supply of a PC will also fall.

When the power restores, it is necessary to turn on and start a power switch again. Use of UPS is recommended in the place where a power supply state is unstable.

(4)Function description

・The function/specifications may partially change and improvements may be made without any notice.

Note:

・The BACnet license number must be registered in each central controller G-50A to use this software BACnet IF.

・Make sure that the license number corresponding to use is registered in the central controller G-50A.
