    Hello guys! I'm making this post to see if one of you can help me. So, here's my problem, I bought 2 thermostats made in the UK. As the huge moron I am, I forgot they use 230V and different plugs/outlets. Now, the plugs wouldn't be a problem, they can be replaced easily. The problemis the 230V. I bought them because a friend of mine has 3 (which work with 110V) and they are really reliable. I emailed the company that makes them and asked them if they stopped making a version that works with 110V and they told me that they never have, and that the ones my buddy has were probably modified by the person that sold them to him. What I wanted to ask you is, how would you do that? The thermostats are made by a company called Microclimate and the model is Microstat 100. I can return them but since they such a good product,if I could modify them and keep them it would be great. Also, theese thermostats will be used to control the temperature of heat tape, which works with 110V.

    Thank you for your time!

    Hard to say without knowing whats inside it. Got a print or some detailed pictures of the inside?
    Do you mean Ministat100? I could not find a Microstat100

    Yes, ministat 100, sorry about that. I can open one up and get you some pictures :D Give me 5 minutes.

    Left to right it's the plug that goes into the wall, then the outlet where you plug your heat source, and the 3rd one is the sensor.

    :oops:It doesn't look like anything you can do to easily modify it. I'd send it back if I could.

    What value is the Grey capacitor? Details on SSR (black box)

    Hey! The black box says:

    10A 277VAC
    12A 125VAC
    5A 250VAC

    Is that the information you were asking for? The only other thing it says is the brand and what it looks like a serial number of sorts.

    Some of it. Grey capacitor. Everything you find
    "brand and what it looks like a serial number of sorts."

    Ok, the black box also says ZETTLER AZ942-1CH-24DE and on the bottom it says 12X14JB.

    Now, the grey box you see in the picture says:

    MKP62 305 ~ X2
    474K 40/11056/B

    And then it has a couple symbols that look like company logos. One is an elipse with the letters CQC, the 2nd one is like an arrow that says ENEC10 and then there's a triangle that says DVE. I hope this information is useful.

    Simple. All you need is a transformer. They are easily available from Amazon, eBay or the like. The only important specification is the power rating. The one linked below is up to 100W.

    Alternatively, you could use a variac (variable voltage transformer) or buy a bare transformer from Digikey or Mouser that suits your situation.

    Wouldn't I need two transformers? Because I would need one to turn 110V into 220V so I can make the thermostat work, and then I would need a 2nd one since my heat source works with 110V and it would get fried if I plug it into the thermostat.

    By running on a lower voltage you are unlikely to do damage.
    I would try it on 110V and see if it works.

    So you think I could just change the plugs for American ones and it will work? I could certainly try.

    What value is the capacitor just below ZD1?

    I have a sim of the cap-based supply and the relay will pull the voltage down to abt 7V,

    That's its working voltage it will have a value as well

    No no no!!! Do not do this. Lower voltages will damage products due to increasing current. Learn Ohm's law. Also this is known as a brownout. Just buy a simple transformer like I mentioned earlier.

    No, no no !!! I = V/R Learn Ohm's law !!!
    This drives a heater not a motor.
