CARLIN 70200 ProMaxx Universal Primary Control.

The CARLIN 70200 ProMaxx Universal Primary Control seems to be a mixed bag in terms of customer experience. While some customers have praised its functionality and performance, others have expressed frustration with certain aspects of the product. One customer mentioned that they had some difficulty getting the control unit to work due to their thermometer being wired incorrectly. They also noted that the directions regarding the temperature sensor line-in could have been clearer, suggesting that adding a schematic of a generic temperature sensor would have been helpful. However, this customer was eventually able to get the unit to work and mentioned that tech support was excellent. Another customer purchased the CARLIN 70200 ProMaxx as a replacement for their oil primary control on their waste oil heater. They mentioned that the manufacturer of their heater recommended against using this particular control, but they found that it worked flawlessly. This suggests that the compatibility of the CARLIN 70200 ProMaxx with different heater models may vary. On the other hand, one customer mentioned that the control unit had too many "useless features" for their specific application. It is unclear what these features are and why they found them unnecessary. Overall, it seems that the CARLIN 70200 ProMaxx Universal Primary Control has its Pros and Cons. While some customers have had positive experiences with its performance and usability, others have faced challenges with certain aspects of the product.
