Solar/electic source furnace wiring

I have a furnace to set up that uses solar hot water as the main source and electric (240) for backup. I need to figure out how to switch between the two sources if the water isn't hot enough. Then I have to have the thermostat turn the correct souce on- 120vac pump for the solar and 240vac for the electric. Any help would be greatly appreciated. Reed B. Turney

    Friends, I believe that the answer provided by 'artiaco07' pertains to solar electric, not solar hot water. The beginning of the answer talks about 'where the solar array cables enter the house' . There are no cables, only pipes. Thanks. Reed Turney

    Benimur, Sounds the closest to what I am looking for. I'm interested on how the relay will switch between 120 and 240. A schematic would be great. Thank you for your time. Reed B. Turney

Hi!
A system is made of interconnected components, each with a different function. A major strength of PV systems is modularity. As your needs grow, individual components can be replaced or added to increase capacity. You can do it this way---
COMPONENTS: solar/electic source furnace wiring - power.jpg

  • Solar ARRAY: consists of one or more PV modules which convert sunlight and daylight into electricity. The modules are connected in parallel and series to provide the voltage and current as is appropriate for the application. The array is usually mounted on a metal structure or roof and tilted to face the sun.
  • Charge CONTROLLER: The main function is to maintain the batteries at the proper level of charge and to protect them from overcharging. Many optional features are also available.
  • Battery BANK: The battery bank contains one or more deep cycle batteries, connected in series and/or parallel depending on the application voltage and current needed. The batteries store the power produced by the solar array for when it is needed.
  • Inverter: An inverter is required when you want to power AC devices. It converts the DC power produced by the solar array and batteries to AC power.
  • AC loads: These are the appliances you want to run with the power. AC loads are typical household appliances.
  • DC loads: DC loads are appliances designed for DC power such as RV and automotive equipment. DC loads make more efficient use of the power than AC loads and therefore may be a better choice for use with home energy systems.
  • Other components: Circuit breakers for safety, meters, wiring, switches and controls.
  • In order to determine what size system you need it will be necessary to determine how much power you really need. To do this a power budget must be developed.

Hi and welcome to FixYa,

Initially, a basic circuitry that includes a thermal probe (or even a thermostat), a logic circuitry (XOR), a driver, a single relay to switch either the 120VC pump or the 240 heater and of course am power supply.

Pls post back if the above idea merits your consideration and that a schematic could be provided. Good luck and Thank you for using FixYa.

A dc disconnect switch should be located where the cables from the solar arrays enter the house. you would have to turn that off.. then you would look for another disconnect whether it be in the circuit panel or near the main unit and turn it on..

How to wire a GE timer switch, model 56922, to my 220v hot water heater, using 2-#10 awg with ground?


You should have received a booklet or manual for the timer unless you got it third party, used, etc.

Anyway, here's a link to the PDF manual for this timer:
http://www.jascoproducts.com/support/manual-downloads/applications/DocumentLibraryManager/upload/15087-15207-56922-Manual-eng.pdf

From what you described, it sounds like you want to wire the timer using a 240 volt, single phase wiring system.

First, download and print out the manual.

Make sure all power is off. Pay VERY close attention to the switch settings in the timer as to how to set them to run the timer motor on 240 volts. If you want to use 240 volts, then set the switches to the settings shown in the CENTER drawing or the one that's labeled 208~240VAC for the timer motor.

After you verify that, see the schematic in the manual that is located in the far bottom right-hand corner of the page and is labeled 208/240/277V Timer, 208/240/277V Load, Double Break wired as single throw.

The labels L1 and L2 mean the power coming into the timer. L1 and L2 should be one leg each of the power coming from a 240 volt circuit breaker in your power panel rated for the duty. The heater should be the only thing on the circuit. The little box on the right labeled Load means your hot water heater.

The ground wire (green) should be connected to the ground lug inside the heater connection box or secured to the metal part of the box. Attach and secure the other end to the timer case or mounting box which should also be grounded.

Set the timer trip switches where you want them.

Double-check all connections before applying power. Check the timer later to be sure it's running and keeping time.

If you are not comfortable performing this type of work, it would be dvisable to hire a competent electrician to do the work.

Bulb comes on, turns off immediately on timer-installed switch


there could be a few reasons for this,
1. the timer could have been damaged during a power surge, = unusable and needs replacement
2. The program set to switch on and off was lost, and needs to be reset, try to operate the reset button, and setting the parameters again., If this is the cace, make sure the backup battery is still ok

My Keurig mini brewer stopped dispensing the water into the cup and the water is now coming out the bottom of the machine! What's happening?????


I just had this same problem. It had to be something with the flow from resevoir to first puncture needle...then I realized that I sometimes used the "use your own grounds" accessory, which in trial and error, had sometimes over-filled. So I figured grounds have clogged the top needle, as opposed to the exit needle that support pages always talk about. I filled the resevoir with hot water and ran that through. The hot water + the brewer making it even hotter did indeed loosen up some old grounds up there and cleared it out...and then I did it a second time to get a little more. If hot water doesn't work for you, try some CLR, but don't use the machine normally. Let it sit in th resevoir for a bit, then use the machines drain function without heating the CLR. Then run a few water cycles through to rinse out the CLR.

I need to connect two switches to one power source in a two gang box. There are two different light sets.


The proper way to wire two switches in a 2 gang switch box to control each light separately is as follows:

  1. Make sure you have the power turned off at the breaker for this box.
  2. Take the HOT (common, black wire) FEED wire and add (2) pieces of black wires to it with a wire nut.
  3. Now you can put one of each of these black wires to the bottom screw of each light switch to provide power to both switches separately
  4. Connect each separate wire to the (2) different lights to the top screw of each switch.
  5. Twist all the bare ground wires together, leaving at least 7-8 inches at the ends untwisted for at least 2-3 of these wires.
  6. Take (2) of these ground wires and connect them to the ground screws on each separate switch. If it is a metal box these area in, connect one ground wire to the box with a green grounding screw also, if not, cut off the extra ground lead near the twisted bunch.
  7. Now twist all white (netural) wires together and install them all under one wire nut.
  8. Make sure the bare wires are not near or touching the HOT screws and fasten the switches to the box.
You now have an approved and legal wiring for (2) separate light switches using the one power source (FEED) already in the box.

Furnace code light flashes 3 times /pressure switch stuck open


Check the intake and exhaust plumbing for any obstructions. I had same issue, turned out to be ice in the air intake plumbing on outside of house. This may be the problem. The pressure switch can be tested by pulling hose from purge motor that goes to switch and applying a small amount of suction. The switch should make a clicking sound.

On off cycling, little air flow, little heat


We had the same problem with the same furnace, CODE 32 DISPLAYED ON THE LEDS. I fixed it by cutting the air inlet pipe and using a hair dryer to supply heated combustion air to the furnace. Once I did that it started to run more and more until it finally heated the house up and works fine, so far so good.

We had a severe drop in temps, sunday it was 40 and rain and that night it dropped to -5 I suspect those conditions contributed to the problem. Wife observed this has never occurred before in 14 years of operation.

Thermastat and furnace


you should have 24 volts between yellow and white wires at the stat when the stat is set to heat and set as hot as it will go. burners should light first then 3 to 5 minutes later the fan motor should fire up. if burner doesn't light check the wires going into the top of the gas valve see if you have 24 volts arriving there from the stat. if you do then the gasvalve is probably bad. you can bypass the action of the stat by jumping red to white on 90 percent of the stats made and in a few seconds the gas valve should click open gas flow to main burner where pilot ignites it. another easy check you can do is flip stat fan switch to on. fan should come on at once. if not then you have either no high voltage to unit or no low voltage ( as in a bad transformer). if the fan comes on you know you have high volts and low volts...by cover i assume you mean the decorative cover but there second cover with the mercury bulbs and all is still there. if you have only the bare subbase then new stat time. sounds like an old furnace if it has a standing pilot, it should be checked for cracked heat exchanger by a pro with a n electronic carbon monoxide detector. NOT a diy item due to the real danger of co poisoning.
