Geyser Wise Max is a solar controller that is used to control a solar geyser in a efficient way as well as detect any problems in your solar water heating system early. Substantial amounts of money can be saved by detecting problems in the hot water system at an early stage.

Features

• Control solar pump based on temperature difference between solar collector and geyser
• Clear display of water temperature, time, day, heating mode, malfunction conditions
• Auto or manual heating
• Easy temperature setting to your requirements (30° C – 65° C) Factory default 55° C
• Four different temperature settings
• Daily programmable timer, four time settings. Default settings to coincide with South African municipal load control programs
• Battery back up in event of power failure
• Multiple protection functions, dry heat, heat failure, earth leakage ,Probe Failure ,overheat , waterleak
• Error conditions alert by error code E1 to E8
