I have had fun this past week installing my new VSM 422, which has proved to be a fantastic addition to my battery
system...at last, I finally KNOW what is actually going into and out of my house bank. One very cool variation to the installation
that I have enjoyed: the VSM has a function that will monitor
a bilge pump
showing On/Off, pump minutes per hour, cycles per 24 hours, and ongoing pump cycles (which can be reset at any time). I was not interested in monitoring the bilge pump
in this way, but I was VERY interested in monitoring my fridge/freezer pump. I have a Nova Kool refrigeration
system installed. By wiring
a relay into the Nova Kool system, I am now accurately monitoring the above mentioned using my VSM. I now know exactly how well my refrigeration
system is working; all for less than $10!
the relay was tricky (for me anyway) as the VSM requires an On/Off 12 volt positive wire, but the Nova Kool has a constant 12 volt supply to its circuit board, so no real simple way to add the relay. This had not been done by anyone at Nova Kool, so it took a bit of trial-and-error, but the relay is finally wired in and the refrigeration and monitor
are working great!
Next addition will be the water
and waste tank sensors.
