Black solar collector sensors are suited to replace the on-roof collector bulbs. Sensor cable black These are 2 core cables which are connected back to your pump station controller from the on roof collectors. It is imperative that this part of the system is never disconnected. It controls the motion of glycol fluids around the thermal collectors. Without this small sensor cable black part working to 100% efficiency the whole system could stop as the sensor opens when fluid temperature rise. Then the sequence of pumping solar thermal fluids begins. Parts in this solar heating group: Solar tube connectors DN12 Solar tube connectors DN16 Solar tube brackets Solar fluid Solar flexible tube connection set Solar C clips Solar fiber washers Solar pump station connectors Solar tube lead slate Pressure relief valve DZR compression tube straight connector DZR compression elbow connector Compression tube insert DN12 or DN16 DZR compression tube to fiber washer flat face connector DN16 x 22mm male adaptor Temperature sensor cable outside Temperature sensor cable inside Immersion heater switch
