Solar Control System Installation and User’s Guide
Note: The solar roof sensor must be 6° higher than the water temperature. The pump must
be ON for a few minutes for operation. When the roof sensor and the water temperature
are within 3°, solar heat will switch off. This differential setting is adjustable in the Heating
and Cooling menu “Diff To Start” and “Diff To Stop” setting in the Advanced Menu.
Adjusting the differential will affect the performance of your solar system. See your solar
professional for the optimum setting.
