I have an older model Emerald Spa (2002-3). I have recently replaced the pressure switch and the pump. Everything has been working fine until the temps went down below freezing here.
My understanding is that there is a Freeze control on this thing. I started out at 103 and now I'm at 79.
I don't want it to bust the plumbing.
No error message on board. Heater light is on. Jets are working.
Will it be safe for the night. should get below freezing again tonight
