Good Morning Mr. Duncan, Hope you are doing well. This would indicate a problem with the water pressure switch when it opens & closes intermittently without an actual change in water flow. I would suggest our kit # 0015S Water Pressure Switch to remedy the situation. Thanks Robert Brown AquaCal Tech Support

Is this the sensor the source of the PO code? I just replaced the manifold and temp sensor with ST00021. I have an older AeroTemp 85K BTU heater.

Good Morning Mr. Harrision, Hope you are doing well. The PO code is in reference to the water temp sensor. The STK0021 would be the correct replacement as long as the wires are hooked up to WS on the control board inside the machine. The item pictured is the Water Pressure Switch & would only be needed if you had FLO on the display with the circulation pump running. Thanks, Robert Brown AquaCal Tech Support

    Is there a picture of the control board with a wiring diagram, Please?? I now have the STK0021 connected to the 'WS' connection on the control board and am now getting a 'dPO' code indicating the defrost sensor is open (which is the same sensor as the temp sensor... correct. When I ohm out the sensor, it shows open (see photo) - This is a brand new sensor. Suggestions?

Good Morning Mr. Farca, Hope you are doing well. The STK0021 is the correct temp sensor & I would recommend the Water Pressure Switch; part number 0015S. The kit has the 6248 pressure switch & other parts to help in replacement. INYO Pools can help with all that for you. Thanks Robert Brown AquaCal Tech Support

Good Morning, Hope you are doing well. If the connection for the flow switch in the AquaComfort is a 2 wire connection then this ECS6248 will work just fine. This switch is adaptable into most heat pumps on the market. Thanks, Robert Brown AquaCal Tech Support
