2-27. ENERGY SAVING SETTING (SYSTEM CONTROLLER)
In this section, an energy saving function which uses electricity meters is explained. System
Controller (UTY-APGXZ1, UTY-PEGXZ1) or System Controller Lite (UTY-ALGXZ1, UTY-
PLGXE2) is required to perform these functions.

FEATURES OF ENERGY SAVING FUNCTION
„ z
Power consumption graph function
Displays by bar graph the power consumption measured by the electricity meter connected to
the air conditioner. Use it to grasp the power consumption usage conditions.
The power consumption for 3 years is saved and the past history can be referenced.
In addition, the data of an arbitrary 2 periods can be displayed for comparison.
„ z
Indoor unit rotation operation function
Reduces the power consumption by rotating the indoor units which are set to forced thermostat
OFF.
Operating the air conditioner even in the spring and autumn when the heat load is
comparatively light may have an energy saving effect.
Because it is an intermittent operation, it does not loose much comfort, and is a control which
is difficult for the user of the room to sense its operation.

● The electric power consumed in the arbitrarily defined group is reduced by rotating indoor
units which are set to forced thermostat OFF.
