When the controller is configured with a solar heater, you set the solar temperature separately. This allows an efficient solar system to run alongside a less efficient traditional heater. Currently there is no way to control this solar set point. We should add a number entity allowing control of this solar set point.
Perhaps if the only heating equipment present is a solar system, we should have the water heater entity control the solar set point directly rather than controlling the heating point.
