Amtrols not so "smart" control

AntnyCAntnyC Posts: 11Member
I have a client with a Amtrol 41 gal indirect equipped with a Smart control. We went through 2 controls in 2 years, at $200 a pop for the part this is getting ridiculous! Can I substitute a low cost thermostat for this control? Any suggestions on specific items? Thanks

    get rid of it

    and use the retro-fit control from Amtrol. Old style aquastat used on the "Z" models. I have a mountain of failed Smart controls. The first generation of them lasted, as they "revised", they lasted a year or two if you were lucky. Check into the retro, and be done with it

    I thought of that, but the smart control has a thermistor thats shoved way up inside the tank while the old type dial control comes with a bulb/ capillary tube thermostat with only a short section of tubing. Do you think it will work effeciently sensing the temp from the bottom of the tank? Thanks for the feedback

    adjustable

    They are both adjustable. If you notice, there are red and blue marks on the lead for the smart control. You should never bottom out either control sensors into the well. You will run out of hot water for one. The capilary should be about 3/4 way in there on both. The retro has a compression type fitting to keep the insertion depth from changing, They come with instructions also
