Elitech MTC-6040 Temperature and Humidity Controller with Cooling, Fan, Humidity/ Lighting/ Alarm Control Output

It is compact and with good quality. It works well. However I’ll advise the eventual purchasers to read the product characteristics before, since the temperature control only send signals to control refrigeration not to heating as well. It is destined to refrigerating units, obviously. The humidity control works both for humidifying and dehumidifying but the temperature control works only to refrigerate. No problem for me because in this project I need to act over humidity and for the temperatures I only need to verify them and alarm if off limits and this works OK.
