Geyserwise Delta T

For use in in Thermosyphon Solar Systems and Normal Geysers

Description

Use as a geyser timer or timer on 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.
  • Daily programmable timer with four time settings.
  • Error conditions alert by warning code E2 to E5 and E7.
  • Electronic thermostat with mechanical thermal cut-out at 90°C. Please note the cut-out temperature for solar systems expected to reach temperatures above this temperature.
