    Simple piece of equipment but does what it says.

    I could not get this to work.

    This sensor works, but it has a few issues: 1- You have to open the box everytime you want to change the thermostat setting. 2-The thermostat settings have a wide range. For instance, the closest I could get the two settings is 60 and 70 degrees. That means when it's 60, my fan is going to shut off, but it won't turn on until it hits 70. If there could be a 5 degree difference, I think it would run more efficiently, and certainly the room would be more comfortable.

    The unit is working good as of now. I will know more after I have it in service over an OHIO winter.The "Techs." Were unable to give me the proper infomation for wireing the temp.alert in to the MTC-302 unit. I had to call the factory.They told me right off how to wire in the resistor to so it would operate properly. Works good.
