Other Crown heaters, specifically newer Crown Boiler Co, indirect water heaters encode the age of that tank within the serial number as follows:. YY or YY - example 05 or 05 both would decode as On by Paul D. I suspect a bad solder joint or board just as do you. You'd want to check the thermocouple before replacing the Honeywell Aquastat Controller LE used on your boiler. This pic is where I took the old jump wire off and added another minus the the female adapter plug seen in the first pic I sent with the green wire.
If I wiggle this, it goes on! Bad solder joint? Again, sorry about the pic problem.
Gas fired Crown boiler Aquastat jumper wire problem. I have a gas fired Crown boiler that I decided to test prior to the upcoming Michigan Upper Peninsula winters I decided to check the jump connection just above that which was giving me problems last year. After wiggling it a bit, it fired.
The jump wire that I tested last year for a good connection looks like the 2nd pic 1st is the Aquastat. If you notice where the green jump wire used to be, I replaced it with a more solid jump wire minus the female part of the connector. Furnace is again functioning as should temp gauge at circapressure at circa 15lbs, very minimal spits of yellow flame above burnersbut I want to get to the bottom of this bad jumper connection.
Anyway, the transformer does have a constant humming noise, not real loud, but nonetheless there. And, probably not important to the matter at hand, but the circulator runs constantly Also, as should be noted, this system bypasses the damper it's there, but not wired Suffice it to say that this is an older system,but I cannot be sure if the Aquastat is that old, though it appears to be.
Thanks in advance! I now have noise in my base board. They have tried to purge it 4 times. I belive it is because the air purger was removed. Removing an air purge is ok IF there is another adequate air purge in the system such that you're not leaving an air trap.
Dec 1, Samuel said: I just had someone come take a look at my Crown water boiler because it's leaking from the PR valve, he said my expansion tank was waterlogged so he let some water out of the tankwhich reduced the pressure, then turned the heater on for about ten minutes, the pressure went up to 30 psi and then water came out of the PR valve again.
If so is there a certain brand I have to use or can I use any tank with the correct psi I need for my home? The TP valve is indeed supposed to open at about 30 psi - so your system is at excessive pressure. It is possible that the expansion tank is waterlogged and can only be fixed by replacement IF. There are other possible causes for excessive heating system pressure including a damaged or mis-set water feeder pressure reducer. If the boiler water pressure is excessive say over 12 psi when the system is COLD then there may be a feed problem.

What's New? Page 1 of 2 1 2 Last Jump to page: Results 1 to 20 of Thread: How to wire Furnas drum switch to instant reverse motor. Thread Tools Show Printable Version. How to wire Furnas drum switch to instant reverse motor Hey guys, been a while wince I've posted, and I'm not too computer literate so bare with me. I'm not sure how instant reversing motors actually work- well this one anyways, but my Furnas Style R RSB4 switch and lathe are vintage.
Lathe is in great shape, and I'd like to keep it original looking. The wiring diagram on motor shows 5 leads: 1,2,4,5,6. Capacitor is stuck in cover but looks like it has maybe a relay in it?
It has 2 leads, and a smaller white ceramic block from what I can see. The motor diagram says L1 goes straight thru to terminal 1, and L2 goes to terminal 2. I don't know if this Inst-O-Verse motor is a new design and will work at all since it appears like a new design? Does anyone have any ideas or know if I'm just wasting my time with this?
I can't find any real help anywhere else on this motor, and as far as instant reverse motors go, some say 6 terminal drums are perfect while others say 9 poles are necessary.Downloads Old Oil Furnace Wiring Diagram oil furnace pump oil furnace oil furnace filters oil furnace canada oil furnace ontario oil furnace toronto oil furnace calgary oil furnace kijiji oil furnace for sale oil furnace ottawa oil furnace nl oil furnace quebec.

It shows the components of the circuit as simplified shapes, and the talent and signal associates along with the devices. A wiring diagram usually gives guidance practically the relative face and concurrence of devices and terminals on the devices, to incite in building or servicing the device.
A pictorial diagram would do its stuff more detail of the inborn appearance, whereas a wiring diagram uses a more symbolic notation to bring out interconnections over monster appearance.
A wiring diagram is often used to troubleshoot problems and to create positive that all the friends have been made and that all is present. Architectural wiring diagrams exploit the approximate locations and interconnections of receptacles, lighting, and permanent electrical facilities in a building.
Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit. Wiring diagrams use customary symbols for wiring devices, usually substitute from those used upon schematic diagrams.

The electrical symbols not deserted take steps where something is to be installed, but as a consequence what type of device is bodily installed.
For example, a surface ceiling fresh is shown by one symbol, a recessed ceiling buoyant has a every second symbol, and a surface fluorescent buoyant has different symbol. Each type of switch has a alternative story and appropriately realize the various outlets.
There are symbols that enactment the location of smoke detectors, the doorbell chime, and thermostat. A set of wiring diagrams may be required by the electrical inspection authority to implement connection of the house to the public electrical supply system.
Wiring diagrams will furthermore adjoin panel schedules for circuit breaker panelboards, and riser diagrams for special facilities such as flame alarm or closed circuit television or supplementary special services.
The thermostat is the control device that provides a simple user interface with the internal workings of your homes climate control system.
By the use of an adjustable set-point, the job of the thermostat is to turn on either the heating or cooling system to maintain the desired room temperature in the home, and to turn off the system when the desired temperature is achieved.
They connect to a two-wire thermostat generally a mechanical thermostat with a mercury filled ball connected to a coiled bi-metal strip.
A basic two-wire thermostat can be compared to a simple single-pole switch that you will find throughout your home, only instead of you turning the switch on and off as required, a mechanical or electronic temperature controlled mechanism is the operator of the switch. They usually operate at 24V ac power, and the source of this control power comes from a control transformer mounted either just outside, or inside the furnace body.
The line voltage feeding the furnace to operate the fan blower motor is transformed down to a safer level of 24 volts the gas control valve needs 24 volts to openand after making a series loop through at least one safety device the most basic and mandatory one is an over-temperature shut downthe power goes up to the thermostat, and when the room temperature falls below the set-point, the contacts close completing the circuit to the gas valve allowing it to open, the main burner to ignite, and begin the heating cycle.
In this the most basic of heating systems, as the temperature of the heat exchanger rises, another contact is closed on the line voltage side of the equation, and the fan blower motor starts moving air through the heat exchanger and out through the ducting in the home. If the fan fails to run for any reason, the heat exchanger will get too hot and the hi-limit temperature device will open the circuit to the gas valve, closing the valve and stopping the heat cycle.
This function allows you to circulate the air in the house by using the fan in the furnace without heating or cooling the air moving through the system.
The obvious down side of this is that if the battery goes dead the thermostat will no longer function. Climate control systems have evolved a great deal in the last several years with the evolution of electronic control. This has made the units more efficient, with added safety features, and with this comes increased difficulty for the average home-owner to repair or replace any parts of the system that may break down and they will, but only when you really need it!
However, the terminals of the thermostats of today are still labeled the same, and provide the same functions as what we have discussed thus far. They just get a little more sophisticated so if you are pre-wiring a new home, check with the contractor providing the HVAC system as to what thermostat wiring is required. A new system may need as many as ten wires like a two-stage heat, two-stage cooling system, heat pump reversing valves, fan control, etc.
These additional terminals are not shown in this diagram.
Now that you are armed with a basic understanding of the temperature control system in your home, you should now be able to identify what kind of system you have, and what type of functions you will need if replacing or up-grading your existing thermostat. I hope this article helped with your question about thermostat wiring.
