5.0 out of 5 stars outdoor timer, May 7, 2007

I mounted it on a pressure treated 2" X 2" post, and set the post in concrete, next to our swimming pool filter. We are saving electricity, as the filter now runs from 7 a.m. to 7 p.m., rather than 24 hours, and the pool remains clean. I used the timer on my one horsepower swimming pool pump, only to find at the end of the season that the pump's plug fused to the timer's receptacle, rendering the timer unusable. Neither Intermatic's fact sheet nor the timer's label states that it is not appropriate for control of a one horsepower motor. I now consider the product a zero star, rather than a five star.

5.0 out of 5 stars AWESOME TIMER, July 6, 2007

This review is from: Intermatic HB31R All Weather, Outdoor Timer. Heavy Duty-15 Amp. Rain Tight Plastic Case (Tools & Home Improvement)

I bought this timer for use with a Flowtron BK-80D bug zapper (see my other reviews). The unit is very nicely made for the money. You mount it with one screw and then you can set it to turn on and off at any time. It comes with two plastic "trip switches" that turn on, and two that turn off. So you can program the unit to go on/off either once in a 24 hour period (by using just 2), or on/off, on/off (twice in a 24 hour period - by using all 4).

I use mine to turn my bug zapper on in the evening time and off at dawn. Works great! The timer has a little plastic flip-up lid to keep the weather out, which is real nice. The 3 prong plug is on the bottom of the unit. It comes with about a 12 or 14 inch cord, which allows you to plug it into an outdoor outlet, as long as you aren't too far away.

The only thing the unit doesn't have is an over ride switch. However, you can sort of over ride it by reaching into the unit (flip the cover up) and manually turning the little round "switch" that is kicked on/off as the dial goes around (which is how the unit works - i.e. the plastic trip switches flip the little round switch as they go by it on the main dial). Once you bypass things using that method, you can leave it and when the next trip switch comes along, it will turn the unit off at the normal pre-set time.

Like I say, for the money, it's top notch. The only thing that would make this unit better would be the addition of another mounting screw hole, which would perhaps allow the unit to be mounted more securely (since it mounts with just 1 screw, you can swing the bottom around if you poke at it). Overall, however, it's fine for the job it does and a very good value. Some double sided tape on the bottom would make the mounting all that more secure if really needed.

Again, for the money, it's a fine product and does a great job of controlling a single outlet :-)

3.0 out of 5 stars poor calibration, December 18, 2008

I bought two of these timers to control Christmas lights and found the calibration of the times to be off. If you can zoom in on the picture, you will see there are two clocks on the dial - the larger outer one where the pins go and an inner one to set the current time. The two are connected and you are unable to calibrate them - who ever lined them up did sloppy work at best. One is close - it comes on within 5 min off the 'real' time - the other one is a whopping 30m out of sync. If you are just buying one, fudging it might be no big deal but I am using 2 and trying to get my lights to come on within 5 mins of ea other has been tough.

These timers replaced two light sensor timers that also were misbehaving so I guess this is just going to be part of my holiday theme from now on...
