• Manage air conditioner usage conditions
Energy consumption of air conditioners can be displayed in an easy-to-understand manner using a web browser.
* The billing function requires a PI Controller and watt-hour meter with pulse transmitter (procured locally).
• Operable without a transmission line power supply unit
The EW-50E unit is equipped with a power supply function. Power supplied by a transmission line power supply unit is not necessary.
Since an outside power supply is not needed, self-sustained operation is possible even when the outdoor unit system is down.
(In cases where the power consumption factor exceeds 1.5, a power supply unit is needed.)

• Energy-saving control
With the addition of an energy-saving control license (optional product), the temperature setting can be automatically changed*
according to the room temperature around the air-conditioner unit to allow greater energy savings without sacrificing comfort.
* 1. With this function, the temperature setting can be changed in +2°C/4°F increments for cooling and -2°C/4°F increments for heating during a set time
interval. In cases where the intake temperature and the temperature setting are significantly different, exclusion from the energy-saving target is
possible.
