    Can you add a freeze guard to a regular Intermatic timer?

    Hi All,

    Temps are still nice around here, but I want to be prepared if/when they drop.

    Have a perfectly functional Intermatic 220v timer to run the pump. All of the "freeze guard" stuff I've found on the 'net includes the timer.

    Is there anyway to add just the temp sensor component to a regular timer?

    If so, I'd guess it has to be tied into the timer, since if it went before it pump power would still be dependent on the timer regardless of temp. And if it went after it, freeze guard power would be dependent on the timer.

    Thanks for your input.

    You can add a separate freeze protection thermostat, such as the Intermatic PF1102, in parallel with your existing timer (so that either one can power the pump). Or you can replace the mechanism of your existing timer with something like the Intermatic PF1102MT combined timer freeze protection thermostat. Intermatic makes a number of related models with various additional features, so you have several choices beyond the specific models I just listed.

    My freeze guard is integrated in my timer as well. Intermatic PF1103T.

    Thanks for the input.

    Looking at the prices, the freeze controls cost almost as much as integrated freeze/timer, so I suppose it makes more sense to just replace the timer.
