I'm relieved the pump relay didn't go first or I would have been forced into an unnecessary and expensive repair. There are models that have DC and AC inputs from the control box and connect to 110 and 220 voltage output to your devices."
"I could hear the relay trying to shutoff, when I operated it in maintenance mode, but the pump stayed on."
"After replacing the relay, the waterfalls now are controlled by the waterfall button on the control panel inside the home as they should be."
"My issue was that the main pump on our pool wouldn't shut off."
"I have a salt water system(swimming pool) that utilizes three of these relay switches."
"I called locally to several pool stores to see if I could get this relay as I had to fix our pool system quickly since we had just sold our home."
"Exact item i needed to replace my previous burned out one."
"Perfect for my Aqualink and way cheaper than pool places!"

"the problem with the old one has different diagram than l8048j 1009. for example the old one only has B1, B2 and new one has B1,B2,B3. ALSO FOR THERMOSTAT : the old one has tv, t, and w but the new one has tv, t, w , tp and z. can you help me connected right."
"Excellent."
"Installed in no time."
"Exactly what I needed and works great."

"My beloved GE Fridge was blowing air but it wasn't cold.After calling a parts specialist, she told me to check the box near the compressor in the fridge."
"But I noticed that our LG refrigerator has the same compressor (Embraco model EGZ 70HLP) as the GE refrigerator that uses this WR07X10097 part."
"Newer style than what I had on my GE Profile bottom freezer."
"After reading numerous issues relating to my GE Profile Bottom Freezer refrigerator, I was concerned I would have to shell out big time $$$$ to either replace or have a technician come in to assess things."
"I was about to buy a new fridge as the compressor was drawing 9 amps."
"Product and Manufacture description CLEARLY states this is a genuine GE part - Amazon post reads "This is a genuine replacement part. I "universal" part with a picture description of how to adapt it for the actual GE part I ordered."

"Just throwing that out, and I like these better than the 12V ones because the pins are bigger, they fit the socket much better than the 12V ones where the pins are skinny, and I feel like with all the vibrations they experience (for my many applications) they will fall out."

"Got this to control my Christmas lights."
"Has been working solid (pun) for quite a while now and no failures."
"When I saw this board for the price, I ordered one to test out with my Arduino Mega board and it took all of 10 minutes to get it hooked up and working like a champ."
"So nothing else mentions it absolutely positively, and I was a bit worried, because the RPi uses a +3V output, instead of the standard +5V. The pins are pretty much laid out like an electrical switch on the wall."
"I used this with a Raspberry Pi to build a touchscreen operated, Wi-Fi connected, garage door control unit and freezer monitor with an custom-made iPhone app."
"First one arrived defective."
"I use 12 of these boards to control my Christmas light shows."

Find Best Price at Amazon"A couple useful pointers that may not be immediately apparent: -to clear the stored usage data, press and hold down the KWH/Hour key in standard mode. Update it to your local rate (you can get this info by contacting your local power company) and press the Pro button to save. 2. the user manual. True to its nature as a "designed for dummies" product, this KillaWatt's user manual is well written and easy to follow! I get that it's probably good for not adding any extraneous power draw, but an option to light it for a second or two would be very useful since a lot of times, the unit would be in a tight spot behind appliances or furniture and it's almost impossible to read the screen without grabbing a flashlight. The device is rated to take max voltage of 125V @ 15A, or a total of 1875 VA. Another reviewer mentioned that his KillaWatt failed after using it to monitor his electric vehicle. My old microwave with a digital clock was drawing close to 3 watts just idling - I've since decided to only plug it in as needed. My toshiba laptop has a nifty software monitoring tool that tells me how many watts it's drawing at any given time."
"I picked up the P3 P44545 to measure power usage of appliances around the house. My utility bills me based on the number of kW.h used for the month. The P4455 does provide an estimate for the cost per day, week, month in $ (nice) and CO2 per day, week, month, but oddly not the kW.h per day/week/month! While it's nice that it computes the cost (based on a rate per kW.h that you program into the device), this isn't sufficient to calculate cost when your utility has variable rates depending on usage (like my utility does). Note that you can derive the kW.h per day/week/month by dividing the total kW.h used by the total hours (both recorded) to arrive at the average power and then scaling according to the number of hours per day/week/month respectively."
"This by far is the best deal you can get on a newer P3 monitor which doesn't loose it's memory when it's disconnected from the power like the older P3 models do. UPDATE: I was just going to order another one of these units and I see that the price has astronomically increased since my last purchase."
