I'm planing on using the RPi to control 2solid state relays to turn on my water heater when I need it

this SSR needs 7.5ma in the input, you should be fine with arduino and RPi setups.

I have used solid state relays for heavy loads. Make sure your electrical load does not exceed the capacity of the relay. Two relays should be used for a 220 VAC power source. One for each power leg. Turning on both relays at the same time is no problem. On the other hand, I'd prefer using a 2 pole mercury relay that usually has a 120 VAC coil. Grainger carries such a unit. example: Item # 12N674 www.Grainger.com

Ok, I use it to turn on a 1500watt water heater and another to control an 8 amp pump.

I would recheck the connections, and then the relay. You could swap the other relay if it's working properly.

You can control this by using a PID, an SSR with a PWM circuit, or a SSR-V, which is an SSR to which you can just connect a potentiometer to control its on/off state. The element itself is either on or off, but using one of those options you are basically cutting power in and out to the element at set intervals (which may be on the order of milliseconds or up to seconds at a time, depending on which you use). I use an SSR-V and a potentiometer only, and it works great. I can basically turn it full on or full off, or anywhere in between. If I were doing it again, I'd use a PID, and I probably will upgrade soon.

Refer to a Sestos Model B2E manual. The manual is downloadable. If you operate this timer in the "Cycle Mode" you should be able to operate the 2 circuits alternately using the provided output relays. Depending on the load requirements you may need an external relay/s.

Yes it will. The individual circuits allow you to adjust which circuits you are using that would max out the input. I have mine set up so that it will only heat water if I turn off a few circuits that would run normal stuff while I turn on the water heater. Once I have hot water I shut down that circuit and light up my normal circuits again.

Not familiar with a Waterbug, but I use the Elk Relay to control my 220v water heater.. It's hooked directly into the Relay. I Plug the Relay into a Zwave appliance module which activates and deactivates the Elk Relay through a Vera Lite command sequence. Hope that helps

I bought this and I connected the line and use the switches to control two scenes

Pedro, I have 3 in the house, one for each water heater. We removed the small timer stops (actually never installed them) in order to control on and off (lever swith on the right side next to the yellow dial) manually...using these timers has save a lot of money on our electrical bill. I have never pushed or pulled the yellow dial--again my application is to use the unit as a basic on off device It is a certified electrical box and thus is better than using a toggle switch.

I put it in a Quelet 10000 watt heater. It allows you to control this unit with a regular low voltage thermostat. The heater I bought seems to be designed to go with this relay. It took me a little bit to figure out how this was wired, but if I recall it was very simple I did this almost 2 years ago

I use "Home Genie" an image for the Raspberry Pi for my DIY system that I am developing. Seems to work pretty well so far. Basically it turns a computer into a home automation server that can process requests. Ideally you'd want that system to be as minimal in power consumption as possibly which makes small microcontrollers like the Pi a perfect platform for this.

Not likely. Your hot water heater needs more energy than this panel can produce unless it is strictly for operating a solinoid/thermostat from another energy scource to your heater.

this device can't do what you're asking. you might want to look at a mechanical timer that gives you several options of turning on and off your appliances

If your water heater plugs into an outlet, a regular timer will work fine. Most water heaters, however, are 220 volt lines on a dedicated circuit, thus you need something more like the WH21. Here's a good reference for you:http://michaelbluejay.com/electricity/waterheatertimer.html

I would not suggest it. Few things.1.) There are three heating "silos" within the unit one for each breaker. So one "silos" wouldn't be doing anything unless you got fancy with the wiring. 2.) I think the device uses only as many breakers as it needs, so if the water is unusually warm I can see it only pulling power from one breaker until it hits the set temperature. If the water is unusually cold it will pull from all three until it hits the set temperature.3.) I do not believe the wiring within the unit is rated for 6-2 so you would probably mess something up.

I use this to control a 2000W hot water heater element. Have had no problems in cold weather. The heating element is for brewing and the controller will take it from around 100W up to 2000W. Have been very satisfied with this unit, other controllers well up into the hundreds of $'s essentially performed the same task. This little unit is a huge amount of value for the buck.

wire the timer on the side of the control gha delivers power to the pump UR what ever devise the controller is monitor
