Heliodyne DTT-84 differential solar controllers are now in stock. This basic controller is a hardwire model with 2 10k sensor inputs and one pump relay output. Sensors are not included with the control.

The PC Board in this control is the same board that Heliotrope General used in their DTT-84 controls. This has proven to be a very reliable controller over the decades. For customers that have an existing Heliotrope control, this Heliodyne DTT-84 is a direct replacement, the board can even be swapped into the old Heliotrope controller.
