This product is designed to be compatible with an air conditioning demand response program. The DR control box connected with your air conditioner and the
Demand Control Signal Receiver (DCSR) which is field supplied needs to be installed in your air conditioning system. A separate arrangement with the energy provider to
access the Demand Response feature must be made.
The power consumption of the compressor will be reduced after receipt of the signal from the energy provider if the DR control box is fitted to the pre configured air conditioner.

During the operation of the unit, if the DR control box receives the signals via the mains input from the DCSR, it will send signals of
DR1,DR2 or DR3 to the indoor unit. The indoor unit display area will display d1, d2 or d3. The DR information(including DR malfunction)
cannot be displayed when the unit is off or under abnormal condition, self clean operation, or LED display feature is activated.
When a DR signal input malfunction occurs, the display area of indoor unit will display "dE" and the unit will operate without DR mode.
Initiating a forced cool operation under DR mode, or going into DR mode under forced cool operation are both valid.
Whilst in DR mode and operation on forced cool mode for half an hour, the unit will go into Auto mode with a SET temperature of 24
O
C.
DR mode is not valid under Self Clean operation but activating Self Clean feature using the remote controller is valid whilst in DR mode.
When the unit goes into a DR mode, it performs moderate operation though the cooling or heating effect may be reduced.
