Function

Contents

Date/time set -up	Sets the date/time of all G-50A units connected to the PC (personal computer)
	as soon as the PC date/time is set.
Time monitor	Confirms the difference in time between the time reference machine (G-50
	No.1) of this system and all G-50A units except for No. 1 and the PC.

*PC means a personal computer on which the integrated software TG -2000A operates.

<Precautions for using this function>

For this system, the G-50A main unit collects the operation data of the air conditioner from the indoor unit to which the G-50A is connected in order to calculate the air-conditioning charge on the basis of the data using the set capacity and charge unit cost. When there is a difference in time between the G-50A main unit and PC on which the integrated centralized control software TG -2000A operates, it becomes unable to correctly execute the calculation.

Consequently, the time adjustment is executed everyday between the integrated software and G-50A to correct the difference in time between each unit. (The time adjustment is based on the No.01 G-50A.) Because of the reasons shown above, it is not basically necessary for this system to adjust the time manually, except for the initial setting. Therefore, when the charging function is used, do not adjust the time unnecessarily.
