Grundfos SQ Flex IO101 Control

The IO 101 switch box is designed especially for the Grundfos SQ Flex System.  The IO 101 is enables the connection of a generator for back-up in the event of insufficient solar radiation.  The switching between solar and generator must be made manually.  When the generator is stopped manually or runs out of fuel, the IO 101 will automatically switch to solar power if available.
