Product Description:

The Geyserwise Max Geyser Controller with Tuya Module is a Smart Wifi Geyser Controller used in pumped solar water heating systems.

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 E1 to 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.

Use as timer and differential control on 12V or 220V pumped solar system.

• 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 – 75°C) factory default is 55°C.
