How do I know that my solar thermal system is working?
You will know that your solar thermal system is working by viewing your solar thermal controller. The Grant GSX1 and GSD3X differential temperature solar controllers will monitor and display the amount of solar power being produced by your system on a daily and cumulative basis.
For further information about the display interface of your controller, please refer to the instructions for your system's controller. You can download these instructions via the Customer Support Centre here by selecting the Manuals tab on the right hand menu in the Solar Thermal Product Support Hub.
