Midea Patented technology 3)Functions Electricity Charge Distribution Electricity charge apportionment can be done easily when the power consumed , its very convenient to bill for power charges of the tenants in a commercial building, offices in a rental building, or rooms in a hotel. The IMM will record the Energy used by each ODU Capacity demand of Each IDU Midea Patented technology 24 Hrs Electricity charges by tenant are calculated by IMM Hourly power consumption of each IDU report to IMM Energy will be apportioned by the ODU to each IDU

3)Functions Safeguard Mechanisms for Electricity Charge Distribution in case of power loss The Indoor capacity demand is calculated according to the set. Temp. /room. Temp./rated HP/running mode, etc. Every hour, the M-interface calculates the Electricity charges of each tenant. And automatically send to IMM as well. In case of 20% of IDUs power fails, ODU will stop for protection. Even if the communication between ODU and Power Ammeter fails , the power consumption record still exists. Even if the power of IMM fails, the record still exists. The idle machines and public area A/C will be distributed to all the tenants.

3)Functions Note: Connecting a power meter allows the charges to be calculated for a variety of usage patterns: such as charges for the power used on a per day basis or just the charges for the power used by the outdoor unit or the charges for the tenants.. Digital Power Ammeter (DTSXXX)

4)Highlights Warning Message Powerful data backup Visual Navigation Warning Message Powerful data backup User Security control Multiple Languages

4)Highlight Visual Navigation Allow to import Building drawing or picture(jpg, gif, png,etc.), to directly control the corresponding IDU on the ‘map’.

4)Highlight Visual Navigation User can put the units in a exact places of the picture Make the operation management more convenient Visual Navigation

4)Highlight Warning Message If error occurs, it will be notified with warning message. The system is able to send error messages to designated mobile phone number automatically via public phone lines.(* optional) * It is necessary to purchase an additional piece of equipment named ‘SMS Modem’ from Midea

4)Highlight Warning Message This message also can be sent via Email. The system is able to send error messages to designated Email address automatically via Midea’s email server.(* optional) * It is necessary to customized this function when you purchase IMM software. And the Email will come from @midea.com.cn

4)Highlight Powerful data backup Double data backup (Inner hardware and Hard Disk Drive) In case of power failure or system crash, the M-interface will automatically backup the data to the equipment. 1. Indoor/outdoor unit name 2. Power distribution data 3. Operation history (by IMM) 4. IMM power On/Off history 5. System configuration 6. Others And the IMM software will also store operational data to the HDD of PC every hour. Note: A backup for power failure UPS is necessary to be field supplied.

4)Highlight User Security control ID and password, user, administrator and service person can be registered separately. Administrators have an authority to set accessible levels IMM functions on users. Service person have even more special authority.
