Thanks. However, when you say small amount of energy what range are you talking of? Do you have some reference with data on this? I mean, stand by energy consumption is small but when added is significant. So I am trying to pin down this small amount of energy with little success. The nominal power of the motor is not so small. Multiplied by many windows may be significant.
