Hayward AquaRite SWG (T-Cell-15) - New vs Old

[SonVolt]

Has there been any upgrades/modifications to the Hayward AquaRite SWG system in the last 12 years? I have to replace the Thermistor 3-4 times a summer. I was curious if Hayward has fixed this issue with newer generation units. It's getting time to replace my T-Cell so thought about replacing the whole unit, but only if there's a benefit to doing so (cracked Thermistor issues etc).

My unit looks like this and was installed 12+ years ago.

Have a read through the Aquarite Wiki article. It explains using an upgraded thermistor.

The newest models have a relay that bypasses the thermistor after startup, so the thermistor does not stay in the circuit the whole time, which should prevent it from failing.

Does your board have a K4 relay or just K1, K2 and K3 relays?

Hayward has made updates to the board adding a K4 relay that is supposed to keep the thermister cooler.

As far as the GLX-PCB-RITE is concerned, only r1.59 have the K4 relay on it.

Here is my board. I'm not sure which "relay" this has???

You have an older board without the K4 relay.
