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.
