Question about Heating & Cooling

1 Answer

I am replacing a 387.9246 Sears zone valve with a WR 1361-103 zone valve. A Sears tech told me to connect the thermostat to terminals 4 & 5; transformer to 1 & 2; and the hot water control to 2 & 3. He could not tell me which terminals to connect the red or white wires. He said ask the maker of the thermostat ! Can you help me with this problem ?

    No, Your note was not helpful. The instructions you recommended were included in the package from Sears.

    My Question is what do I do with the existing red and white wires. Presently, there are wires (each containing a red and white component) hanging from the thermostat, furnace control and transformer.

    (1) From the thermostat, do I hook the red wire to terminal # 4 and the white to # 5 ?

    (2) From the transformer, do I hook the red to terminal #1 and the white to # 2 ?

    and (3) From the furnace control, do I connect the red wire to # 2 and the white to # 3 ?



    Or, does the color of the wire make a difference ?



    I'm afraid that I will short out the $200 zone valve if I connect the red wire to where the white wire should go.

    I hope this clarifies my questions.

    I forgot to add that the specs and instructions for Sears zone valve 387.9246 clearly noted what terminal the red wire should be hooked to and what terminal the white wire should be connected to. Check out the old specs, please.

Hi,

Not exactly sure what you are asking as the red and white wires would be t-stat wires which you said he wanted you to hook to 4&5....

Check this out...

    Hi,

    Yes, that clarifies things....I was not following you at all....



    Here goes....the simple verision....terminals 1, 3 & 4 get the whites.....

    terminals 2 & 5 get the reds....



    So... the transformer is #2 red #1 white...



    The t-stat is #4 white and #5 red...



    The furnace control is #2 red and #3 white...



    What I often do is go to than auto parts store and buy an inline automotive type fuse holder...I use Autozone...

    I then install the fuse holder in the hot side of the transformer... the hot side will be marked with a "R" and the common side with a "C" The "R " side is the wire that will go to the #2 terminal....wire the fuse in that line to protect the transformer and the valve...install a 5 amp maximum fuse... a 3 amp is better... in that fuse holder....this way if you mess something up you will just blow the fuse and not the transformer or the valve...the valve motor should only pull .4 amp and the t-stat will pull even less...set the heat anticipator on the t-stat to .4 -.5 also...if it has one...



    Hope this gets you going... sorry about the confusion... it's tough to get a grip on exactly what is going on through the written communication sometimes...:-)

02 wr250 stator rotor came apart and shot a peice threw the case.shut down with kill switch. Replaced stator rotor Try to pull start, nothing but headlight shines bright any tests to suggest


Hi, Larry and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

How do I connect a 24v damper motor with 6 colored wires red white yellow green blue black to NO COM NC terminals.


Choose two colors of the thermostat wire, and connect them to the NO and COM and connect them to the zone control board leads for the zone intended. Almost all zone valves spring return open when deenergized. So ensure the zone valve is open with the system is off. At the base of zone valve there is a set screw that needs to engage the damper valve shaft in the open position with the motor in the spring release position. Most zone valve are 90 degree moment from full open to full shut. If you have a Carrier zone valve, they go full open to full shut in 45 degrees of motion. Your open stop need to be set so the valve stops in the full stop position.
To help understand the operation of a zone system, say you have 2 zone system and zone 1 thermostat initiates a heat or cool demand. Zone 2 valves energizes and shuts and zone 1 stays open and allow air to heat/ cool zone 1. If zone 2 thermostat simultaniously initiates the same heat/cool demand, the zone 2 valve opens and both zone heat/cool. When either thermostat is satisfied the opposite zone valve closes and when both thermostat are satisfied both zone valves open.
Hope this helps you understand zone operation. The same works for higher multizone systems.

I just purchased a house with brand new furnace wired to a RTH2300 Honeywell thermostat. It only has two wires running to it. I can't seem to get it to work in "manual mode"-where I set it on...


?? Connect Wires 5.

Labels don't match?

If a wire does not match any terminal on the thermostat,

see next page.

Alternate Wiring

If a labeled wire does not match any terminal

designation, see diagram below.

Do not use C, C1 or X wire. Do not use B wire if you already

have O wire. Wrap bare end of wire with electrical tape.

This thermostat cannot be used if your old thermostat had

any two of the following wires: R, RC, RH, 4 and V.

Place a jumper (piece of wire) between Y and W if you have

a heat pump without auxiliary/back-up heat.

?? Connect Wires (cont'd)

Programmable Thermostat RTH2300

Set jumper JP1, on the back of the thermostat, if you

have connected a wire to the G terminal.

Incorrect jumper setting: An incorrect setting is

noticeable in a gas or oil heating system. When heating

starts, you will initially feel cold air coming out of the vents

as the fan is running before the furnace has enough time

to heat up the air.

?? Set Heating Fan Control 6.

HG Leave the jumper in this factory-set

position if you have a gas or oil furnace.

HE Place the jumper to this position if you

have an electric furnace.

Set jumper JP2, on the back of the thermostat, if you

have a heat pump.

Incorrect jumper setting: The heat pump operation

will be reversed, i.e., it will cool in Heat mode and will

heat in Cool mode.

?? Set Heat Pump Reversing Valve 7.

O Leave the jumper in this factory-set

position if you have connected O wire to

the O/B terminal.

B Place the jumper to this position if you

have connected B wire to the O/B terminal.

Replacing WHITE-RODGERS manual thermostat with 3 wires ( red, white, blue and installing Honeywell electronic thermostat RTH110B, how do I connect it? The heating is not central, baseboard heating.


I have only seen one Honeywell thermostat that would work with a 3-wire heating system.

I would replace it with a White-Rodgers 1F80-0471. They are about $100, but they are a good thermostat, and they work well with the 3-wire zone valves.

Most other thermostats have the "Y" terminal that you need, but do not control the zone valve correctly.

How do i install a zone valve in my hot water heater. I need the schematic from boiler controller to the valve. if I tie the first floor to one valve , the rooms (2) will be on the last section before the...


The two zones have seperate supply and returns, correct? If not zoning will not be possible without piping the system in that way. Assuming the piping is correct, for two zones, you will need two zone valves, one cut into each zone. The wiring will vary, but for a 3 wire zone valve, (Taco), power from the transfomer goes through the thermostat, into terminal 1 on the Zone Valve, Terminal 2 on the zone valve goes back to the transformer, (24v common), and also to one "T" terminal on the aquastat (boiler control), and Terminal 3 on the zone valve goes to the other "T" terminal on the aquastat.

For a Honeywell, or other motorized Zone Valve, power again goes from the transformer, through the thermostat and into one side of the motor contacts/wires (depending on brand), the other motor wire goes back to the transformer, (24v common) Then the two end switch contact/wires go back to the T T terminals on the aquastat.

If you are using motorized zone valves, and only 2 of them, the transformer in the aquastat will be strong enough to power them.

Hope this helps

A duo therm thermostat (p/n 3105058) was removed because it would not operate the air conditioner/heater in a firan fireside camper. it was knocked loose from the wall damaging it.the thermostat is for use...


a. Remove the cover of the thermostat.
b. Connect the RED wire from the air conditioner
to the “RC” terminal on the thermostat.
c. Connect the “YELLOW” wire from the air conditioner
to the “Y” terminal on the thermostat.
d. Connect the “BLUE” wire from the air conditioner
to the “H” terminal on the thermostat.
e. Connect the “ORANGE” wire from the air conditioner
to the “G” terminal on the thermostat.
f. Push the thermostat wires into hole in wall and
fill excess hole with insulation.
g. Mount thermostat base to the wall with screws
provided.
h. Check all thermostat wires on base to ensure
they are completely clear of the bimetal coil of
the thermostat. Adjust if necessary.
i. Replace thermostat cover.
If nothing operates on the air conditioner, remove the
return air grille assembly and verify the red, orange, yellow
and blue wires are properly connected (red-to-red,
orange-to-orange, etc.).
Next, disconnect the red wires and check for 12 volt
DC between the red wire from roof section and the orange
or blue wire from roof section. If no voltage received,
refer to Section F2. If voltage is received, the
problem lies with the thermostat or thermostat wires.
Next, disconnect all 4 wires (red, orange, yellow and
blue) from the thermostat. With the thermostat set on
COOL mode, FAN mode set on AUTO and HIGH, and
temperature selector set lower than the room temperature. Check for continuity between terminal RC (red wire)
and terminal G (orange wire); and RC (red wire) and
terminal H (blue wire). If continuity is achieved on each,
proceed with the next step.
Set fan switch to LOW. Continuity should NOT be present
between terminal RC and Terminal H, but present between
the other terminals (Y & G) and terminal RC.
If all of the previous checks are good, the thermostat is
good, do not replace it. If any one of the previous checks
are not correct, replace the thermostat.

Kenmore Dryer will not heat


Does the limit switch have a reset button on it or is it an auto reset? Have you tried depressing the reset button on it if it is a manual reset? Have you checked your voltages to the gas valve, ignitor to make sure they are being called to come on? Trace your electrical connections from your electronics to these items. If they are not being told to come on, then you know it is the electronics. Also, have you checked the continuity of the door switch, and the ignite? These are all suggestions that must be ruled out before replacing parts.
