Pool Heater registering Low Pressure Error message

if the intellitouch is properly wired to the heater, it should all be automatic and you should be able to control it all from the remote.

there should be three wires connected to the circuit board behind the manual control on the heater (labeled "POOL", "SPA", "Common"). Those are the wires that the intellitouch uses to communicate with the heater.

You can download manuals from the Pentair website.

lo usually indicates insufficient water flow and/or pressure switch malfunction.make sure filter is clean and pressure is in normal range

Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.

I had this problem with ours last year. I replaced the water pressure switch and it began working fine. We later had a symptom that the blower would start but it would not ignite. The ignitor rod was corroded so I took it out and sanded it with some sandpaper---worked fine...until I dropped it trying to reinstall and it broke. Bought a new one and it works fine now.

Today's problem is related to the blower now.... it is always something, isn't it?!?

I happen to work for Rome Industries and can help you out. The "LP" code on your control board represents "Low Pressure". This is referring to the refrigerant pressure within the unit. The unit is equipped with a low pressure safety switch that when activated shuts the unit down. This could be caused by a refrigeration leak, a stuck thermal expansion valve, or even a faulty pressure switch. If you live within the state of Florida contact Rome Industries and you will receive a free of charge service call including parts and labor as long as your unit is under warranty. If your outside of the state please contact your dealer to handle the claim. Have a good day.

I had the same issue...you don't have enough gas pressure.

turn off skimmer or add water to pool the heater is registering low flow.
