Geyserwise Delta T Digital controller

The Geyserwise Delta T model is designed for the compatible use with a 220V circulation pump and stand alone use for geyser timing purposes.

With 2 probes, it check the temperature in both the solar collector and geyser, then communicating to the circulation pump to make it circulate the water when heating is necessary.
