Aqualink Freeze Protection


Well-known member

We have a pool/spa combo that run off 1 filter pump. In pool mode the pool returns are on and the spa returns are off. In spa mode the spa returns are on and the pool returns are off.

In the aqualink freeze protection menu I have selected filter pump and spa to have freeze protection. My question is by having both of those checked for freeze protection will the system cycle between pool mode and spa mode so that all pipes periodically have water running through them to protect the pipes. I could not find anything in the manual that says whether freeze protection cycles between pool and spa mode.

thanks for your help.

I believe the Aqualink will cycle between pool and spa mode every 15 minutes when in Freeze Protection. That will put stress on your actuators.
