    I have a Waterfurnance 5 series with DSH, aux heat, 6 ton unit, closed loop system about 5-6 feet deep, 6 ton system heating/cooling about 4200 sq feet (which includes the 1200sq foot unfinished basement). I have the serial number posted in my other thread I started.

    The unit seems to be working properly, only been here a few months, electric usage isn't scary and our home is comfortable.

    I opened up the cabinet to get a visual on the goods, saw the two control boards and the intellistart. I also saw what looked like Christmas lights, tis the season!

    Could someone explain these LED codes to me?

    ABC Board
    LED 1 - 9 rapid flashes, off , solid illumination for a second - off - repeats
    LED 2 - 3 rapid flashes, pauses, 6 rapid flashes, pause, 7 rapid flashes, pause - repeat
    LED 3 - illuminated green

    AXB Board
    LED 1 - illuminated for 2 seconds (green) off for 2 seconds - repeat
    LED 4 - 2 rapid flashes , off , repeat.

    Thank you for your time and helping with my ignorance. These all seemed unimpressive from what I could interpret of the manual but it was hard to understand for me as I'm not familiar with the lingo.

    Look at the electrical schematic on back of panel. It will have the codes.

    well who would have thought to look flip the cover over!? I just sat it on the ground with the waterfurnace pretty side up as not to scratch the aurora wave! haha thanks!

    I haven't been back down to the basement to review the schematic on the panel.

    Any recommendations on a multimeter for a home DIY guy?
    Is TRUE RMS crucial to me?
    What will I even be doing with it you might ask. I imagine I will attempt to measures temperatures with it. incoming/outgoing air temps. incoming outgoing water temps, incoming outgoing water temps from DSH.
    I also have a door bell and an outside light I can't get to work and will probably be testing a few random things around the house.

    Once my son gets older (currently one) I imagine we will test and experiment with conductivity of materials and have all kinds of fun too, thinking long-term.

    Ultimately I would love to measure amps and calculate watts if I can figure out how to do that, compressor, blower motor, pumps, etc...

    Lastly, can someone explain to me the benefit of a second water heater with the DSH? Is there substantial savings for using a second tank? I imagine it's essentially a holding tank of 100 degree water from the DSH that the hot water tank pulls from thus improving the hot water tank efficiency.

    With a single tank you have competing heat sources. The elements want to re-heat the water when ever there is a big enough draw. The Desuperheater wants to heat the water whenever the heat pump runs. If the elements have the tank at 125* the DSH might not even run. With twin tanks each heat source can do it's own thing.

    Thank you for the information. Makes me want to buy a small 40 gallon water heater to hook up.

    I did adjust the thermostat of my hot water tank to 125 top and 100 bottom per the water furnace manual.

    Any thoughts on a multimeter?

    Go buy a good tool.

    If you want to see electricity try Field Piece. The man that introduced me to how to do sheet metal, said he did not mess with magic. He could not see electricity therefor it was magic.

    Field Piece are expensive but seem highly rated. For my intermittent DIY nature I went with the Southwire 10040N. http://www.southwiretools.com/tools/tools/10040N
    I like the simplicity of the autoranging and the temp probe. I appreciate your response.

    When I grew up on the shores of Lake Erie I was taught never go boating on the lake without a good compass. Then I was taught if you need it believe it. Those truths have kept me alive for over 65 yrs.

    The same holds true for magic. Electricity must be magic because it can not be seen by the human eye.

    Tools and schools rule this company/family. Saving a few dollars could kill you and you can not read amp draw so you do not know how much work is getting done.

    Southwire meter was complete junk. returned it. looking at used Flukes on Craigslist....I wonder how long till I break down and get a fieldpiece?

    The first time you bet your life on what the meter tells you. If it is not too late.

    I warned you electricity is magic because you can not see it. So if I am looking at magic, I want the best Harry Potter glasses I can get. I took 460VAC in one hand and then out the other to ground. It was caused by a wild leg of a 3 phase system with the disconnect off. By luck I am still here typing and bothering Doc 20 years later.

    They are used tires for a reason.

    You do not really need true RMS graphs if you are on grid. Besides is your home wired 3 phase?

    Galion is not far and I have a light week. I am less than two hours away. Want help?

    We are on grid no idea what 3 phase is?

    Glad you are doing well!
    Blown away by your input and willingness. I hate to have you drive out here to the country cause I have no idea what I am doing. What's a typical hourly rate for your line of work? Or the friends and family rate at least?

    I don't even have my buffer tank yet let alone know what kind or how much pipe to get for an install...

    I will keep what I charge to the privacy of a phone call. I know I do not charge enough.
