Picking the right Intermatic Pool Timer can be a little overwhelming when review all their options. In this guide, we hope to narrow down your field of choices and explain the important stats to check
Ratings to Check
if you’ve seen a Intermatic catalog, you will know how many different acronyms, ratings, and specifications are tagged on each one of these pool timers.So, to cut out the confusion let’s focus on the key things you should check
Refers to the circuit voltage required to operate the timer mechanism and that can be dispensed / controlled by the pool timer. Residential pool pumps are wired with either 110V or 220V, for most mechanical timers, you’ll need to know the specific voltage your pump is wired for, to pick a compatible timer. most digital pool timer listed below are dual voltage, meaning they can be wired to 110V or 220V.

Max Load Amps
This rating defines the pool timer’s circuit capacity. The simplest explanation I’ve heard to explain amperage, is that the voltage is the straw, the amps are the juice that delivers the energy from the juicebox, I mean breaker box.
Residential pumps are wired for 110V or 220V but their amp draw varies according to the pump’s horsepower. For the UST1102 1 HP Century pump motor pulls 15 A on a 115 V circuit; whereas a UST1152 1.5HP Century pump motor puuls 18.6 A on the same 115 V circuit.
if you plan to wire muliple devices to an Intermatic Pool Timer, you’ll need to ttally up how many ampsto make certain it does not exceed the timer’s Max Amp Load.
Freeze protection devices are pool automation controls with built-in thermostats; they monitor air temps and will turn on the pump if temperatures drop below a set point. Flowing water is less likely to freeze and burst your pvc plumbing then if it was left o to settle. Freeze protection devices can go a long way in preventing a costly replumbing repair.
Freeze protection devices come with some timer packages, are available as accessory add-ons, or standlalone freeze protection devices
Pool owners living in cold states or in areas subject to freezing cold fronts (Texas, I’m looking at you) freeze protection timers are a great addition. if you’re in persistently cold states like Michigan, Minnesota, the Dakotas and the like, it’d be best to fully winterize and drain your pool and its plumbing.
Commonly referred to as a fireman’s switch, a timer’s heater protection feature turns off the heater about 20-minutes before the pump is scheduled to turn off. By shutting down the pool heater before the pump, the heat exchanger is allowed to cool down gradually. Fireman switches were required on older gas pool heater models because they heater cabinets did not dissipate heat fast enough.
