Brand new to the forum. Just bought a foreclosed house this past year; everything related to the pool works great except I am unable to turn on the pool heater from the control panel inside the house. The heater works fine when I turn it on at the actual heater box. The control panel inside acts like everything is working fine, but it just doesn't seem to communicate my input to the heater box. It communicates fine with the outside service panel in every other aspect. So I took off the access panel to the heater box and this is what I found inside:
There are 2 wires that are not connected to anything. These wires run down and out of the heater box and into a sealed conduit; not sure exactly where it goes from there (probably one of the conduits that emerges near the service panel). It has the look of a temperature sensor wire, but I am really new to all this stuff. Not sure what it is supposed to be connected to inside this box, but it obviously was run there originally for some reason. If you look down below there are 2 terminal that are directly jumped together by a yellow wire; I'm wondering if this is where my 2 unknown wires are supposed to be connected?
Also, I found this unknown part sitting in this opened package inside the heater box. Anyone know what this is and why it would be there?
The heater is a Pentair MasterTemp 400.
The control panel is a Pentair IntelliTouch System i7+3
I would call a pool repair company, but I live an hour outside of Las Vegas and no one will even come out to my house without charging me a minimum $400, and then at least a repeat $400 for the following repair trip after making the diagnosis and ordering in any needed parts.
