Help with Freeze Protection
I hope everyone is enjoying their Holiday weekend with their friends and family!
We have a Pentair-equipped pool with Easytouch controller and a multi-speed pump. The 4 speed pump has the following four speeds configured:
1. Freeze protect (500)
2. Pool (2000)
3. Cleaner (3250) - the cleaner has a booster also.
4. Spa (3450)
Both the Pool circuit type and the Spa circuit type have freeze protection turned on.
The issue is that when the pump cycles from pool freeze protect to spa freeze protect it switches RPM to the Spa mode (so up to full speed). As the equipment pad is on the other side of the wall from our bedroom I can sometimes hear the pump.
I basically have two questions here:
1. As the pool mode operation sends some water into the spa and some to the pool (the spa spills over to the pool), do I need to have freeze protection on the Spa circuit or will pool mode suffice (I live in Houston so we don't get long hard freezes, just heavy frost and the odd freeze)
2. If the answer to (1) is yes, am I missing a setting on the Easytouch to make it stick to the 500rpm speed in both pool and spa freeze mode?
