I have 2 of these combos, 1 delivering to the radiator and one taking over after the radiator.
I have only tested on one of them so far, but I noticed the values being a bit odd. I calibrated at 78% fill level, and when the tank was full it still showed 78%. When I tried manually calibrating I noticed the raw value was 770 from about 45% and all the way up to 100%. Is this because I have 2 of these in the same loop, making it impossible for the mps to get a correct reading? I have the pressure sockets, or whatever they're called on both tanks.
