Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Sounds like the remote valve/"sensor" isn't communicating with the pump. When was the last time the batteries were changed?

Brand new install, it is linked OK, water temp varies up and down instead of steady, goes from 95 to about 120. Hard to deal with esp. In the shower.

I'm going to open this backup to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
