Does this require a separate 120v circuit to run the timer? Can I used this if I just have 240V and ground at the water heater and no neutral?

you can run it off of the 240V circuit. It does not require a separate 120v circuit. FYI... I have had mine for over 3 yrs now and it has worked great..

It does not need a separate circuit for the timer. I ran the 240 to the timer and (I think) 12 gauge from the timer to the water heater. I'm not qualified to answer the second question, but given the way you have to wire the timer I would guess that you can't wire safely w/o the neutral.

It is set to use just to 240 volts supply for the Water Heater. You do not need a separate 120 volt circuit. It is VERY simple to connect.

Grounding the neutral is not allowed per electric code. The EI 600 model is the same timer but does not require a neutral wire.

I have used it by wiring in a water heater timer it works great shuts off completely when I don't want it heating and timer powers it up 1/2 hour before I want the area warmed up then the thermostat on the unit keeps it consistent from there until I have the timer set to de-energize that circuit.

120V I have never tripped a breaker; however, I do not run it on a circuit while other items are running. Another words, I run it on a dedicated circuit. We use this rice cooker for large family gatherings and tailgating. It's big!

You definitely have to wire this into your 240v circuit. No plug on this unit. Hope this helps.

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 cannot tell from your description of the transformer you have or are replacing. Do you have 120 volts going into transformer and wanting 12 volts coming out? Is your transformer being used to power your timer? You need to know what voltage your timer is. 120 volts is the house current. Usually the timer for sprinkler are 24 volts and sometimes 12 volts. Let me know the voltage of your timer.

it only takes AA batteries. Don't know why someone thinks it takes 110 electric outlet. this unit does NOT plug into an outlet for power; compatibility with a solenoid is a pointless question. It's a sealed unit. You put in AA batteries, connect to water hose, set the timer. That's all.

The unit has 2 120 V.A.C. hot wires from the circuit breaber panel and a bare ground wire. The hot wires are each 120 V.A.C. making the timer box used on a 240 V.A.C. hot water heater, the bare wire is a ground wire.

I installed the timer switch I bought for my daughter in her home. I know it does not require a neutral wire. I really believe the documentation that came with it showed it could be used in a 3-way arrangement but I left that with her so I can't refer to it as to how that would be done. In her situation it just replaced a single-pole switch.

You can use timer to control 120 volt coil on contactor... and then use contactor to handle 240 volt load... this timer requires neutral wire: http://waterheatertimer.org/Install.html#neutral

It should work for a 120V floor heating system. One has to make sure that the rated wattage of the heating (resistance) coil used is not greater than the thermostat spec. I have used over a dozen of these thermostats for 240V baseboard heaters with no problems. However, I did mange to burn one up when I ganged two heaters that totaled close to the upper wattage spec, so I would include a safety margin on the upper margin spec by at least 10% (90% of the spec).

I believe it should work --- if not directly, then by using the ground, neutral, and single "hot" wire with the pressure switch to activate a relay controlling the 240 volts. (I am assuming the 240 consists of 4 wires --- two "hots", one neutral, and one ground. If this is not so, then disregard my comments.) Square D offers several models with specified pre-set on/off points. Their switches are easy enough to "tune" to your particular needs. Some models include extra-easy "external" adjusters. Within reason, you can raise or lower the on/off points together or tune them individually. Good luck; I think you can do it.

The one that I have is 110/120 only. You would need a converter, (available) to operate it on 240 volts.

Nadine, you must drink alot of coffee if you need 240VAC timer ;) But seriously, you could use a 110 volt timer similar to this one. Do a test first: unplug your machine, fill with water filter and coffee, turn the switch on, then plug it in. if it makes coffee you can use a timer, if not..no

Yes, you should be able to. Just a reminder, the Amico timer will need power to operate, so you'll run 12 volts to the timer from your battery, then you'll use the timer as a switch relay to turn on and off your water heater. So, you'll cut the 12 volt wire that runs your water heater and connect to the Amico timer. The timer will now make the 12 volt connection via a relay within the timer switch to turn on and off your water heater based on when you program the timer to turn on or off. Hope this helps!
