Geyserwise Max Electronic thermostats

Geyserwise Max
For use in 12V and 220V pumped solar water heating systems

Description
Use as a geyser timer and use as timer on a thermosyphon solar system.

Clear display of water temperature, time, day, heating mode and malfunction conditions.
Auto or manual heating.
Easy temperature setting to your requirements (30 – 75°C) factory default is 55°C.
Four different temperature settings.
