45SMART FUNCTIONS
ENGLISH
If the refrigerator receives a Demand Response 
signal from the utility company, the refrigerator 
will turn on the Grid LED on the refrigerator 
display and control its power consumption 
according to the signal. The refrigerator will 
respond to the signals received from the utility 
company as long as product performance is 
maintained.
If the refrigerator receives a Demand Response 
signal, the refrigerator will operate in Delay 
Appliance Load (DAL) or Temporary Appliance 
Load Reduction (TALR) mode.
Delay Appliance Load (DAL)
The refrigerator responds to a DAL signal by 
providing a moderate load reduction for the 
duration of the delay period.
This mode controls functions that consume a lot of 
energy such as adjusting the cooling system, 
running the defrost cycle, and making ice.
• When the refrigerator operates in DAL mode, 
the Grid LED is illuminated on the refrigerator 
display.
• DAL mode is automatically deactivated after the 
period stipulated by the DAL signal (max. 4 
hours) or when you override the Smart Grid 
function.
Temporary Appliance Load Reduction 
(TALR)
The refrigerator responds to a TALR signal by 
aggressively reducing the load for a short time 
period, typically 10 minutes. This mode reduces 
energy consumption by stopping the compressor 
and controlling the functions that consume a lot of 
energy such as the defrost cycle and fan.
• When the refrigerator operates in TALR mode, 
the Grid LED is illuminated on the refrigerator 
display.
• TALR mode is automatically deactivated after the 
received duration (max. 10 minutes), or when 
you override the Smart Grid function. The mode 
is immediately deactivated and the refrigerator 
returns to its normal state when the door is 
opened or closed, or the dispenser is used.
Override Smart Grid Mode
To ignore the Demand Response signal from the 
utility company and override the Smart Grid 
function, push the Smart Grid button while the 
refrigerator is in Smart Grid mode.
When you override the Smart Grid function, the 
refrigerator ignores the Demand Response signal 
and is no longer controlled by the utility company 
until the next Demand Response signal is sent. You 
can also override the Smart Grid function using the 
smart phone app.
