My Daybreak spa by Weslo quit working completely. I had an electrician look at it and he thinks the transformer on the circuit board is blown. The last time this happened the spa was under warranty and they sent me a new control pack. Since the spa is no longer under warranty and their control packs are very expensive, I need to know which control packs I can use. Theirs is an electronic one. I am looking at the HydroQuip HT500-T Spa Control
or the HydroQuip CS800.
Any help would be appreciated.

Thanks
Kris

Just about anything will work, it's up to you though to determine the amount of plumbing rework that is required to make the situation more appealing. If I had my druthers, for simplicity and future service, I'd stick with the CS800.
