The Power Distribution Integrator (PDI) tracks outdoor unit energy consumption broken down by indoor unit operation ratio. The PDI requires a field supplied wattmeter per outdoor unit and can track the outdoor units power consumption for up to one outdoor unit and 48 indoor units. Power consumption is displayed by indoor unit on the two line LCD display. If the user desires to download the data to a PC or a printed report the Power Distribution Integrator can be used with the Advanced Control Platform (ACP) and AC Manager.
