The Geyserwise Delta T Thermal Controller allows you to set your geyser’s heating times and temperatures.

Features

• Clear display of water temperature, time, day, heating mode and malfunction conditions on solar system and geyser.
• Auto or manual heating.
• Easy temperature setting to your requirements (30 – 65°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 to E9.
• Electronic thermostat with mechanical, thermal cut-out at 90°C. Please note the cut-out temperature for systems expected to
  reach temperatures above this temperature.
• Differential controller 220V pumped solar system.
