2-25. Energy saving setting on System controller

By installing System controller or System controller lite, energy saving function using electricity me-
ters can be performed.
¢ Features of energy saving function
• Power consumption graph
Displays the power consumption measured by the electricity meter connected to the air condition-
er by bar graph, and makes it easier to understand the power consumption conditions.
– Power consumption data for 3 years can be saved
– Past record can be referenced as history
– Data of an arbitrary 2 periods can be displayed for comparison
• Indoor unit rotation operation
Reduces the power consumption by changing the indoor unit which is to be set forced thermostat
OFF in turn.
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 changing indoor units
which are set to forced thermostat OFF in turn.
