Question: I run a housing development and want to set up Magna’s for BTU metering. Can this be done with these pumps through a Delta T option?

Answer: Yes, it can be in Differential Temperature control mode. It is accomplished by adding a temperature sensor on the supply side, P/N 98477669 that includes a six foot 4-wire AWG22 cable cable which is to be connected to the analog input shown below. The Magna 3 series already has a sensor built in on the return.

The last step is to go to SETTINGS, drop down to ANALOG INPUT and select the sensors parameters of 0-10V or 4-20 mA . Note that each pump must have its own sensor even if connected in a lead-lag control.
