JED Engineering supplies the Helio-Matic HM5000C solar pool heat controller that is used to control the circulation of pool water through the solar collectors. This solar pool heating controller has the ability to operate 12 volt as well as 24-volt valves. In addition, this controller can run a separate pump that is exclusively used for solar circulation.
The Helio-Matic HM5000C solar pool heat controller circulates pool water through solar collectors when there is sufficient heat. The pool heat controller will cease circulating the water when the heat is insufficient to be picked up. This solar pool heating controller, offered by JED Engineering, also allows the user to make adjustments to get the required temperature for the pool water. It includes an inbuilt time delay feature that is for pool sweep considerations. The valve will be activated instantly after the pool heat controller starts picking up the solar heat. The pump turns on eight minutes after the activation of the valve, to avoid pool sweep malfunction. However, the delay in operation of the pump can be disabled.
The Helio-Matic HM5000C solar pool heat controller can also be used only with the valve. In this case, the pool sweep pump is connected to the output of the controller. This pool sweep hook up method permits the pool sweep to function only during the solar collection. In addition, the piping system is cleaned off from air, when valve system only is used.
