Compact control for your heating or cooling needs. It comes with a thermistor on about a 40cm lead for easy positioning. Menu is a bit confusing initially but some searching did turn up some information. I would recommend looking up the "W1209" setpoints. but here are some cheat codesP0 Heating/Cooling ModeP1 Hysteresis (delta T)P2 Set Upper Temperature Limit (Degrees)P3 Set Lower Temperature Limit (Degrees)P4 Temperature Offset Correction (Calibration)P6 High Temperature Alarm? reset? not sureOnce setup it was working well, easy trouble free operation. Screen is super bright and easy to read and will show a current temp reading too for extra utility. It's a basic stand alone setup for cooling or heating functionality.

I have these controlling some small exhaust fans on my quail cages. If you're electronically inclined, these are a pretty simple setup. If not, YouTube/Google will get you straightened out. They seem to be pretty reliable so far and temp readings appear to be accurate when compared to my meters. Overall, it's a great product for any DIY project you might have around the house.

I got the 2 pack FainWan Digital Temperature Controller, one for the greenhouse and the other for the chicken coop. Each temperature controller will keep the temperature of the environment at the set temperature before turning on the heater module to raise the temperature or the fans to lower the temperature of the environment.The board looks well built and it appears to be working and measuring the correct ambient temperature of the surroundings. The kit does not come with a manual and the help documentation is a couple documents on the product description page. I searched the internet and found videos and documents that explains how to setup the controller.There is only a single relay so you can only control the temperature at one setting. If I want to control the temperature range in the environment I think i will need two of these controllers. I will have to search some more to get some detailed answers.
