Product details

The Intermatic 178T24 is the replacement freeze protection thermostat used to protect pool and spa equipment and plumbing against freeze damage. It turns the pump on when outdoor air temperature falls below the setting on the adjustable knob.

Setting the trip point

The knob adjusts from 45 degrees down to 32 degrees in 5 degree increments. Setting it higher means the pump starts earlier and runs more; setting it closer to freezing means it runs less but leaves a smaller margin. Most owners land somewhere in the middle for their climate.

What is in the box

This listing is the thermostat knob and its wiring. The mechanism and the relay unit are not included, so it is intended as a repair part for an existing freeze protection installation. It is rated for 120/240V installations and for pumps of 1.5 to 3 HP, and it is used both as a pump control and as a heater thermostat control.

Fitment note

Our source lists this thermostat for the Intermatic FP1102T and PF1103T freeze protection units. The second model number appears with its letters reversed in the source data, so compare it against the label on your own enclosure before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

What does this thermostat do?

It watches outdoor air temperature and turns the pump on when it drops below the temperature you set on the knob, so water keeps moving and the plumbing and equipment do not freeze.

What temperature range can I set?

45 degrees down to 32 degrees, in 5 degree increments.

Do I get the whole freeze protector?

No. This is the thermostat knob and its wiring. The mechanism and the relay unit are not included, so this is a repair part for an existing installation rather than a complete assembly.

Which units is it listed for?

Our source lists it as the thermostat for the Intermatic FP1102T and PF1103T. That second number is written with the letters reversed in the source, so check the label on your enclosure before ordering.
