    Johnsons Thermostat wiring help?

    So, while cleaning my tubs today, I noticed that my power strip connected to my thermostat was not working. Fantastic.

    I pulled apart the thermostat, took a mental note of where all the wires go, then tried to quickly put it back together. Well, halfway through I couldn't find my pliers, so I spent about 30 minutes looking for them...still never found them. By the time I gave up looking and just used a different tool I had forgotten which terminal to place the "hot" (black) wire. The johnson controls manual is no help to me... I don't understand the diagrams at all.

    Could someone walk me through it or take a picture of the guts of their thermostat?

    The power strip comes on, but when the thermostat switches off it doesn't turn the power strip off. I'm totally confused and mildly frustrated. Help?

    I tried all possible places for the hot wire... only one makes it come on at all, but it won't shut off.

    The other two terminals don't do anything... Is my thermostat dead? Or am I doing something wrong? Please help guys... I don't like my guys being at room temp for so long.

    Can you post the manual? I'm not familiar with this thermostat, but I might be able to decipher the manual lol.

    ok, looks to me like you should have wires from the wall plug going into Terminal Block 1 (TB1)

    Your hot wire goes into the terminal labeled 120

    Your neutral wire goes into the terminal AC Com

    Now the power strip or whatever goes to your heat source appears to have the hot wire connected to the TB2 ON terminal on the right side

    The neutral looks like it doubles up in the TB1 AC Com terminal

    looks like there is a jumper between 120 terminal on TB1 and the C terminal on TB2

    it might, as I said I'm not familiar with these thermostats. All of the Jumpers firmly seated on the headers?
