||Digital Temperature Controller FAHRENHEIT
|A really useful device. I have found many uses for these controllers. How could you even buy the parts for what these units cost? The units tolerate the temperature extremes of my geographic location and also seem to have a high ESD tolerance.
The instruction sheet needs to be corrected for some items however;
the spec on the Fahrenheit unit quotes the Celsius unit spec of minus 50. Fahrenheit spec is -58F before it LLLs.
Menu P4 would be better stated as calibration not correction. Changing the calibration allows you to increase the sensor cable length and then re-trim it back in the P4 menu to former accuracy.
I have used these temp controllers in a 4 stage peltier cooled night sky camera to control the cooling. A heatsink fan controller for a 100W Broadband minus green LED grow light . And a furnace flue booster fan control.
All of the above just keep on working.|

||Works really well
|Works great, temperature is very accurate. I used it for my RV hot water recirculation system and has been working flawlessly.|
||This is a 10 !
|I use this device as the basis for my own commercial refrigeration thermostat by incorporating high current relays with it to start my motor loads.
Thus far its been 100% reliable, easy to apply and very economical!|

|took for ever to calibrate.comes with instructions but not easy,too many variables to fool with.not for the impatient person. used mine to start digital timer when water boils for precisely timed soft boiled eggs.|
