Hi,  

Two situations:

1.       Temperature controllers that are equipped with a "Triac" are likely to create problems because if the "Triac" fail it will put the controller in full open position thus generating problems.

2.       Do not connect a variable transformer to a temperature controllerÉ this will also create problems to your controller.

Hope this help

All -

Just as a followup to this information, we pulled 12 controllers from our Organic lab rooms last week. Seems to be a real issue with heating mantle controllers.
