    Re: **HELP: Johnson A419 Thermostat!!!**

    Your T-stat could be reading wrong temps because you did not twist the shield back on the probe wire. Johnson controls are very sensitive to low volt interference. I just did a Johnson controls system at True Religion Brand Jeans design facility and it can be very comlicated. Try twisting the shield which is a silver jacket inside the rubber jacket back around the probe wire(back towards the actual probe end) and tape it off. BTW, as Dr. Del stated, you should be using the same wattage Flexwatt as the higher wattage stuff is going to get hotter than the lower wattage stuff.

    BTW, I'm not seeing a probe wire hooked up in your pictures. Did you hook it up at all?

    Im NOT. I hit menu. Then it flashes SP SP. So I put in the TEMP that I WANT. Which is 93 for a 90 hot spot in the bin that they are in. So it sets and then right away goes to that temp on there currently (175).

    Thats what I don't understand....

    Re: **HELP: Johnson A419 Thermostat!!!**

    IT says 175 on the DISPLAY but I put the little round thermometer on top of the hot side in the bins and it reads the following HOT spot temps:

    On the 10 watt Flexwatt (per ft) 3"- 110 HOT spot
    On the 6 watt Flexwatt (per ft) 3"- 92-94 HOT spot

    I'm so confused...

    I already know I have to get a new thermostat for the 10 watt Flexwatt. That way the 6w has its own thermostat and the 10w has its own thermostat. IM CONFUSED as it WHY it reads 175 on the display as the temp in the room is between 78-85.
