• Failure, etc.:
An energy saving function operates only when the related units are operating normally. When the
power of the electricity meter and the outdoor units connected to an electricity meter and the Sys-
tem controller is turned off due to a failure, etc. the energy saving function will not operate normal-
ly.
• Explaining to the building tenants:
During energy saving function operation, control from the remote controller may be overridden by
the energy saving control. For this reason, it is recommended that the building tenants be informed
of this beforehand.
¢ Installation restriction and requirement of energy saving units
• Only 1 unit may perform energy saving control at a time.
When energy saving control is performed by System controller (UTY-APGXZ1, UTY-PEGXZ1),
stop energy saving control such as forced thermostat OFF, outdoor unit forced OFF, and outdoor
unit capacity save from the building management system through the following units:
– BACnet gateway (Software)
– Network converter for LonWorks
When energy saving control is performed from multiple points, trouble may occur.
Energy saving control prohibited
BACnet gateway
• Electricity meter installation required for some functions.
For using following functions under energy saving control, installation of an electricity meter is re-
quired.
– Power consumption graph display function
– Peak cut control
When these functions are necessary, install an electricity meter in advance with referring the in-
stallation manual.
