2-23. 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 Input Power graph function
„
Displays by bar graph the Input Power measured by the electricity meter connected to the air
conditioner. This graph can be used to analyze the Input Power.
The Input Power 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 Input Power by rotating the indoor units which are set to forced thermostat OFF.
Operating the the air conditioner with this function in the spring and autumn when the heat
load is comparatively light may have an energy saving effect.
Because it is intermittent , and there is little change in the rooms temperature, the occupants
may not even sense it's operation.
● The electric power consumed in the arbitrarily defined group is reduced by rotating indoor
„
units which are set to forced thermostat OFF.
