Solar Lord Roof Sensor HWC1 and HWC2 models

PLEASE NOTE: These sensors are no longer available. You are better off replacing the controller and sensors with a controller with a digital display. Through the digital display, you will be able to monitor your system to see that it is working correctly. The Senztek SolaStat 1-2 controller is an appropriate replacement.

Solar Lord Roof Sensor HWC1 and HWC2 models

This sensor suits the Solar Lord Solar Hot Water Controller HWC1 and HWC2.

If you are just replacing the roof sensor on your system, we recommend you check the circulation pump. Just because the pump motor is running does not mean it is circulating water as it should and this will damage your new roof sensor. With some models of solar hot water systems, your best option may be replacing everything at once with a complete pump station. Please contact us if you have questions about this before you purchase this item.
