Analog solar controller - elios easy

Differential analog thermal controller - Elios Easy for solar heating plants: it compares temperatures of fluids in the collectors and the storage tanks and, when the difference is greater than DeltaT, starts the heat exchange through the pump. 3 temperature inputs from NTC sensors and 2 on-off relay outputs SPST. Additional thermostat for driving auxiliary heat source. LEDs row show the value of measured temperature and others LEDs show output relays status.
Configuration of 6 different system layouts. Adjustable antifrost function.
