Solar thermal controller – a mandatory control element for solar systems with forced circulation of the heat transfer fluid. It controls the process of heating the heat transfer fluid from the sun and monitors the condition 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 electricity consumption.
