Hello,
I am curious if other Indigo users are controlling their home hot water recirculation pump with an I/O unit and the program. If so, what schedules are you using?
A standard hot water recirculation pump timer is quite limited, but with Indigo, so many options get my geek going. I have experimented with a scheduled event several times a day/week and even tried triggering the pump to run for five minutes every half hour in the day during the Summer months. I really had no idea how much of a dent that I could put in my electric bill or considered that recirculating the hot water "wicks" the temperature away from the water heater. My current schedule has dropped the average daily electrical usage for the home by 8 kWh! For my family and larger home, that is almost 10% of our daily usage! As they say, "your milage may vary".
The next step is to implement motion sensors by each sink and refine the usage even more...
