The Intermatic 230 Volt Residential Timer is an electro-mechanical time switch for residential 230-volt installations, used to put a fountain, aerator or de-icer on a set daily cycle. It is the residential-duty option in the line, sized for homeowner ponds rather than for commercial sites.

The switch reads its incoming supply on its own and operates on anything between 110 and 277 VAC, so there are no selector switches to flip and no pins to insert during installation. It is built around a 40-amp design, which leaves headroom for the pump and motor loads typical of pond equipment.

The timer arrives in a compact weather-resistant housing rated as a UL Type 3R outdoor enclosure, so it can be mounted outside where the equipment actually sits. The mechanism can also be retrofitted into other Intermatic enclosure styles if an installation calls for a different housing.

No fixed warranty term is published for this item. It is covered against defects in materials and workmanship on arrival, so contact Adventure Motion support with your order number and photos if it arrives faulty or does not match what you ordered, and we will confirm coverage and handle the claim.

Normal wear and consumable service life are not covered, and neither is damage from installation outside the stated compatibility or operating conditions.

Can this timer be mounted outside?
Yes. it comes in a weather-resistant ul type 3r outdoor enclosure, which is rated for outdoor mounting near the equipment it controls.
Do i need to set it for my supply voltage?
No. the switch detects its incoming voltage automatically and operates anywhere from 110 to 277 vac, so there are no selector switches or pins to configure.
How much load will it carry?
It is a 40 amp design, which covers the pump and motor loads used by most residential pond fountains and aerators.
Is this the same as the 230 volt commercial timer?
No. this is the residential-duty model. the 230 volt commercial timer is the heavier-duty unit, rated 208 to 277 volts at 40 amps with up to 12 on/off cycles per day and a manual override switch.
Can i move it into a different enclosure?
Yes. the housing is designed so the mechanism can be retrofitted into other intermatic enclosure styles if the installation calls for one.
