I was doing some math for a pump size for my system. I have 6 loops of 250 ft. Am i better off with going with the 006 or the 007 ? I will be using at least a 40 gallon water heater. Dont want to have any excess noise while running the system.
I went out to test the defrost thermostat sensor and got an OL on my meter which means it's open. If that sensors bad, will it cause it to not go into defrost?
