Solar thermal controller – a mandatory control element for heliosystems with forced circulation of the heat carrier. It controls the process of heating the heat carrier from the sun and monitors the state of the heating system as a whole. Control of the solar system operates as follows – the controller receives data from temperature sensors that are installed at the outlet of the solar collector and in the storage tank, analyzes them, and controls the circulation pump, which allows optimal use of electricity.
