System Operation If Connected To Demand Response Power - Sanden GS3-45HPA-US Owner's Manual

System operation if connected to Demand Response power

 There are no special settings for the Demand Response. The system will run once
power becomes available and the temperature in the tank drops below the set point
of the tank thermistor.
 If connecting the unit to Demand Response power, ensure that the off peak tariff
provides a minimum of 5 hours continuous power, as it can take at least four hours
to fill the tank unit with hot water.
If the ambient temperature is lower than 50
 If the unit is connected to Demand Response power and hot water consumption has
been higher than normal, hot water might not be available until the next power
supply cycle.

Daily frequency and amount of hot water consumption may also affect the duration
of the heating cycle operation.
Select the electrical supply mode that best suits the customer's hot water
consumption. The type of off-peak connection may need to be changed
if hot water supply is not maintained as required.
