W1209 Temperature controller.
The W1209 Mini thermostat Temperature controller is a 12-volt Temperature controller with a 7-segment display and 3 switch keypad for setting temperature and other parameters. An NTC thermistor is used for temperature sensing and has an accuracy of 0.1 C. Ideal for controlling a heating element at a specific set temperature.

It does what was expected. I am bit uncertain about supply voltage. Mine is regulated on 14v. I did not have bugg converter at hand and connect to 14v. Seems to be OK.
Service was excellent , received a faulty unit on 1st delivery , they replaced a new unit following day at no extra cost.
Im no expert in electronics but Youtube has helped. A small instruction manual would help. But otherise its a good product
This nifty little temperature controller is easy to use and highly accurate. It has well written, clear instructions in the manual (available on Botshop website). The PCB is well designed and has slots around the relay pins (for mains use). I would however recommend that an addition relay or SSR is used for heavy loads. Will definately order more in future!
My experience with Bot Shop was excellent. Product was delivered within 48 hours.
