The Intermatic V45471R34 is a mechanical pool pump timer switch that automatically adjusts to seasonal changes with the changing lengths of the day. This particular model, part of the Intermatic V45471R range of time switches, is designed for use in zone 34. It is a 3PST switch that is 120 volt ready and is able to carry up to 40 Amps for each pole. The switch carries Intermatic’s Skipper feature, but unlike some of the other switches in the V45000 series, does not have Carry Over feature.
The unit comes in a package of dimensions 9.5 x 6.5 x 5.2 inches and weighs 4.7 pounds. It is installed in a NEMA type 3R steel enclosure. The real dimensions of the enclosure measures 8 1/4 inches (20.9 cm) in height, 5 1/4 inches (13.3 cm) in width with a depth of 4 3/4 inches (12 cm) in a beige finish. The dial type time switch has a hasp with a hole for locking. The hasp can be locked to secure the side-hinged enclosure door. The holds are permanently attached in the enclosure. The unit comes with a combination 1/2 inch to 3/4 inch nominal knockouts of which there is one each at the back and each side of the enclosure, and there are four on the enclosure bottom.
The switch is rated for a current of 40 amperes for each pole, and operates within a temperature range of -40 to 54 degrees Celsius. It is a 3 pole single throw switch. The clock motor voltage rating is 120 volts and at a frequency of 60 Hz, the power input is rated 3 Watts. The unit can be installed on a wall via three holes. The switch is UL and CSA listed.
The 3PST configuration of the switch allows 3-phase lighting control. The astronomic dial is designed to automatically adjust as the length of the day grows longer or shorter through the seasons. The unit comes with the trademark Skipper feature, which allows the lighting control to be eliminated on certain selected days. The unit is designed with three screws to install the skipper. The clock motor terminals are independent, allowing for greater precision in dial time.
Quality and Performance
The Intermatic V45471R34 is designed for both indoor and outdoor use, constructed of durable materials that users have found to live up to the promise. It can offer at least 6000 operating cycles and has a timing range of 24 hours repeated for 365 days. One of the biggest benefits of the switch is its ease of installation. Self-installation is possible with the help of the accompanying manual, without the need for technical help from an expert. Another advantage of the switch is its ability to automatically adjust the dial by daylight, helping to conserve as much energy as possible. Automatically adjusting astronomical time clocks are being increasingly preferred to standard time of day clocks. Dial is adjusted by latitude according to geographical location and this allows effective and energy efficient lighting any time of the year.
At an average price of a little over $200 and available with a 1 year limited manufacturer warranty, the product guarantees quality for the dollars spent. Several online retailers offer the product at as much as 17 percent less than the list price, some with product promotions and financing options for credit card holders. While the price may appear on the higher side, Intermatic products are known for their durability, and many people who have used the switch have found that in the long run the cost is recouped in maintenance fees and energy costs saved.
Anyone looking for a 24-hour mechanical pool pump timer switch with astronomical features will find the Intermatic V45471R34 a good buy. The product has received general praises by users and they have recommended it to their friends and family.
