Easy to install and works great. The instructions are a little hard to follow. Suffice it to say that this unit assumes the ambient temperature is 75 degrees and will display a cht that starts there. So, if the ambient temp is less than 75 degrees the unit is assuming its hotter than it really is. So, you subtract one degree for each degree below 75. If its hotter than 75, the unit assumes its cooler than reality, so you add one degree for each ambient degree above 75.
