Pros:
Cheap. Easy to handle. Controls an electrical switch according to the temperature
Cons:
It was a bit confusing at first to understand the correct connections.
Other:
I am using it to control a cooling fan in my attic which pumps the air outside when it is too warm. The connections are: Thermocouple red to 1. Thermocouple blue to 2. Ground to 3. 220V to 5. Load (fan) ground to 3. Load 220V to 8. 5 to 6.
Bottomline:
I am very pleased with this device. My attic is now cooling without me having to manually switching the fan on in the morning and off at night.
