My spa heater has an issue where it trips HL2 frequently as it is heating the water to 104 - the trip occurs shortly before reaching the high temperature. I typically reset the error but cycling the mode on the spa heater's physical control to off and back to spa - it then lights and reaches its proper temperature. Last year I tried to fix the problem by changing the limit switch itself (adding a heat paste), changing the internal bypass, changing the unitherm governor and adding a heat shield. Nothing fixed the problem and its very hard to duplicate - happens some days and not others. Probably happens more on hot humid days and there is minimal ventilation where the heater sits (and a tree over it). After my experience and reading a few others who have the same problem, I decided to live with it.
But I do have a question that perhaps someone better schooled in RayPak could answer. Might there be a way to automate the reset process? I control the heat and temperature from my iPhone using Jandy automation. Obviously I cant add a function to Jandy to fix an HL2 error, but perhaps I could add a power relay to reset the heater? It would be great if I could get the reset done without having to trek into the pool equipment pad. I know when the problem occurs because spa temperature is in the 90s and not 104 as set.
Any thoughts?
