Firstly, the cost of running a 50 watt rod alternating with an 8 watt rod works out at less than $3 a month...hardly worth the added hardware and development costs of switching. Secondly, having switches that can be manipulated from outside only adds to the possibility of someone goofing it up! Murphy's Law Rules! Thirdly, Dampp-Chaser is currently working on a humidistat that will do nothing if the piano is in a suitable climate and will only function if that climate goes beyond the "safety zone". I also wnat to address the earlier postsuggesting the dry humidistat for a humid environment.... DON'T DO IT!! You don't need a lower cut off point, you need more power. My first question would be:- Are you using 50 watt rods? If not..get them! If you are and they are not sufficient, use an add-an-outlet and add another 25 watt rod. This won't cause any problems as the system just becomes more efficient and hopefully will actually turn off occasionally.... at the right humidity! Your problem is that there is insufficient power in the current systems you are using to get the humidity down to a satisfactory level, by adding more power it will be able to bring the humidity within the piano down to less than 50% RH...where you want it. The Dry Humidistat will just mean that on the odd occassion that the humidity does come naturally down, you'll stress your pianos by dragging them even further down than they should be... You'll be over drying them. Email me privately if this isn't clear enough.
