ABSTRACT:
A summer operation apparatus for a circulating water heating system includes a separate auxiliary device installable in connection with the system controller. The auxiliary device includes an external temperature sensor for sensing the outside temperature and also a first switching device for controlling the system pump. A second switching device converts the signal of a signal line of the temperature sensor of a controller so that it can shut the system valve. The auxiliary device also includes a control for controlling the first and second switching devices according to the external temperature thereby implementing a summer operation state for pump and valve. A timer device can be included for starting the pump intermittently in the summer operation state for short periods at a time.
