W09D is a microprocessor-based electronic differential controller. Its typical use is for controlling thermal solar panels, but it can also be used in other applications that require control based on the difference between two temperatures, such as chillers, chillers or natural air conditioning systems with air recirculation and many other applications.
The instrument has 3 temperature inputs PTC/NTC/Pt1000 or and an adjustable digital input, the 3 relay outputs can be used for temperature control (OUT) and for temperature alarms (AL1, AL2).
