For use in 220V pumped solar water heaters

Smart Wifi Geyser Controller. Download the Tuya Smart App and manage your geyser from your phone anywhere in the world.

Download For IOS 

Download for Android

Using the app will enable you to:

  • View your geyser temperatures
  • Set your temperatures
  • Switch Your Geyser On And Off from virtually anywhere.
  • Manage Your Geyser like a wifi geyser controller.

Description

Use as a geyser timer or 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.
  • 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 systems expected to reach temperatures above this temperature.
