Pools and spas heated by the sun need to have an accurate controller for two reasons. First, it is important to maximize the utilization of the solar energy available by circulating water through the collectors when heat can be picked-up and not circulating when heat could be lost through this circulation. The second reason for a controller is to allow the pool owner/operator to accurately adjust the maximum desired temperature.

HM4000C - The HM4000C utilizes the existing pool's circulation pump for solar heat pick-up. The HM4000C has a front panel switch which provides for nocturnal pool cooling instead of heating. Cooling is used in conjunction with the pool's filtration pump being allowed to run during the early dawn, cooler hours. The HM4000C works in conjunction with the Flo-Verter 12VAC valve, allowing circulation by the pool's filtration pump either through the solar collectors or bypassing the solar collectors.

Flo-Verter - The Flo-Verter valve is a 12VAC, 2' valve. The Flo-Verter never needs lubrication, utilizes permanent magnet synchronous motors, has an extremely low CV factor due to the curved/directed flow channel inside the diverter, and may be mounted in any position except upside down.

One port is identified 'FLOW TO COLLECTOR.' An adequate length of three wire color coded cable is permanently attached to the Flo-Verter valve and these three wires connect to the color identified terminals at the Helio-Matic controller. There is never a need to check flow direction as an error is impossible if the same colors are connected together. The Flo-Verter is a non-positive seal valve and the diverter has a small hole, which allows the collector to drain when the system is off. This draining prevents collector damage due to freeze ups.

Sensors - The standard sensors are one AS-2-10 aluminum sensor for collector simulation and one IS-1.0 sensor which is clamp inserted into a drilled hole in 1 1/2" or 2' pipe.
