Hello, I bought a house a few years ago that has a pool/spa with an older automation system. That system is on the brink of death right now (constantly shut offs, won't run at all sometimes, etc), and I'm looking into options to replace it. For reference, here's the current system in use:

It controls the heating of the pool and spa, two sets of lights, and a blower for the spa.
The quotes I've gotten to replace it have been around $5,000, because they all want to replace the actuators, salt water system, etc. In the meantime, I found these two things in our basement:


For reference, the original owner of this house worked at a pool construction company, so I'm unsure if these were just around, or if he originally planned to move over to this system. Not knowing much about it, is this also an automation system that could replace what I currently have? I understand it's probably older as well, so I'm unsure if I'm better off selling this for a little bit of cash towards the new system or trying to integrate this. Any insight is appreciated, I don't want to commit to a huge expenditure unless I have to.
