Freeze Protection - Sort of

[jamescd]

New here but can’t keep chasing my tail.

FP will activate as intended. But eventually the pump stops to 0 rpm.

However FP is still indicated on the system - so other than manually starting the pump - I can’t do anything with it.

I did manually turn it on at 0200. And despite the 28 degree temp - sometime after that (it’s now 0600) - it’s off again.

Ideas?

Jim,

You need to give us a clue what equipment you have...

Thanks,

Most freeze protection does not run the pump continuously until the temp rises, but only in increments of time (whatever the manufacturer programs), turns the pump off for a time, checks temp and runs again if needed. You may have checked during one of the "off" periods.
Best freeze protection is a pump scheduled to run during the "freezing" hours, usually at least from 2:00AM until 8:00AM, but with a VSP at a medium speed much longer or 24/7. Even at a low speed you are usually protected and the cost in electricity is far less than the damage a frozen system can be. Also, peace of mind knowing you won't have an issue.
