Geyserwise Dual thermal controller


R1,080.00 Excl VAT

Geyserwise Dual is designed to handle both geyser related aspects along with the PV control as apposed to the water temperature control in the collectors with the Delta T and Max.

 


For use in PV Waterheating Systems

Description

Use as a geyser timer

  • Clear display of water temperature, time, day, heating mode and malfunction conditions.
