Hello,
I have a coil heat exchanger sitting in the sump. Hot water recirculates (via recirc pump) through the heat exchanger as needed to heat the tank. I would like to create a program such that if the recirc pump turns on based on temperature setting, turn off after a fixed amount of time. I do not want it to turn off based on temperature.
This will minimize the overshoot and save some electricity.
Thanks
