8.6. Energy save operation
• During cooling operation, or heating operation, when pushing the [ECONOMY] button in the wired remote controller, energy save
operation start and [ECO] sign is displayed at LCD display panel of wired remote controller ([ECONOMY] sign is displayed at
LCD display panel of wireless remote controller).
• When energy save operation start and temperature differences is +1K (=indoor suction temperature - setting temperature) for
cooling operation, or -1K for heating operation for 30 minutes, thermostat OFF point shift to 0.5K.
(This means thermostat OFF point shift up +0.5K for cooling, thermostat OFF point shift down -0.5K for heating)
From this control, it is judged that indoor side heat loss is small, then reduce compressor frequency. This means energy save
operation.
• Those kind of operation continue maximum 4 times. If temperature is out of range (thermostat off +1K for cooling, thermostat off
-1K for heating), operation release from energy save control. But energy save control cannot be released by pushing ON/OFF
button of remote controller, but still effective. When pushing [ECONOMY] button once again, energy save control released.
