Dear John,
It is sucking more juice than it should. That is why the breaker goes(to protect the wiring in the unit or house from frying and burning up the joint)
Air Conditioning mechanic is needed...........

Here are the wiring diagrams for both the components. Just cross check and be assured that you have selected the correct input voltage depending upon your country's specifications.

Positive and neutral on satchwell geyser thermostat


with only 2 terminals it will not matter which wire goes on the terminals
a thermostst is just a spring loaded switch that is adjusted by the knob
the points of the switch are pushed apart by the thermostat medium and the pressure need is set by the spring from the knob
so it is power in -power out= no matter which wire is connected to which terminal

I am wanting to wire a Baxi 105E boiler to a Danfoss 102 mechanical timer. The boiler has 5 wires = red, blue, earth, black and yellow. The Timer has six terminals = 1 DHW, 2 HTG, 3 COM, I (earth), 5...


1) Contact baxi:
http://www.baxi.co.uk/contact.htm

2) Which boiler wires? I don't know. Page 24 manual.
Manual says to disconnect link between terminals 1 and 2, and instert timer in-line.
http://www.acwilgar.co.uk/Boiler-Manual-PDF/Baxi/Combi%20instant%2080E%20&%20105E.pdf

2) I can tell you about the timer wiring.
Timer is 230Volts
Not sure if you have British Hot-Neutral 230Volt, or Hot-Hot 230Volt.
Wiring is same 2 wires, but words to describe are different.
Let's say you have Hot-Neutral 230V
Connect Hot to L6
Connect Neutral to N5
This will power the timer so it runs and keeps time.
You can get Hot-Neutral wires from Hot-Neutral that arrive to power the boiler.

Now the timer terminals are separate.
E terminal is Earth or ground.
The Common is Hot wire.
The timer then turns on-off and switches back and forth between DHW and HTG.
HTG is heating
DHW is defrost.
Timer has 2 sets contacts.

When timer activates first set of contacts, then DHW defrost terminal receives power from Hot wire on Com terminal. At this time, all power is cut to HTG heating terminal.

When the defrost cycle ends, then the heating circuit receives power, and then the timer has programming that opens and closes a second set of contacts going to HTG heating terminal.

Which wires from boiler connect to each terminal, I am not sure.

Just wired up the gp24 ,connected mains,switch and nuetral, working on manual mode but clock not turning


Reverse wires on terminals 3 and 4

1) GP24 appears to be 24-Hour version of Greenbrook T100 series mechanical timer, with Grasslin analog time dial.
http://waterheatertimer.org/pdf/Green-brook-T100_CInstructions.pdf
http://waterheatertimer.org/How-to-set-timers.html

2) If clock is not rotating, then probably your wires are reversed.
Reverse wires on terminals 3 and 4.

3) Power from Mains, and wire to Load each have 2 wires.
Hot live from Mains connects to terminal 3
Neutral from mai9ns connects to terminal 1
Neutral going to load connects to terminal 1
Hot going to load connects to terminal 4

I need to replace an old Thermostat that just has 3 wires coloured Red, Blue and Yellow. The Honeywell THR830TUK Thermostat I have bought shows 5 wires on the diagram. I'm not sure which wire goes into...


The honeywell THR830TUK thermostat does not require a neutral as shown in the instructions.Connect the LIVE to terminal "1" and your YELLOW SIGNAL wire to terminal "3".
Connect your EARTH (if you have one) to the EARTH connection on the top left hand corner of the thermostat and blank off your NEUTRAL wire with a block connector.These instructions were supplied to me by Honeywell Customer Support.Hope this helps.

How do you wire a intermatic t103


I'm looking at the T-103 sitting here in my office.
Terminals are labeled: A 1 2 3 4
I have about 10 different Intermatic timers on the shelves & each is a bit different

The T103 has a 120Volt (or 110V) clock motor
You need a white Neutral wire to operate the T103 clock

120V: Let's say your Load (light, fan, pump) is 120V
The white Neutral from breaker box connects to Terminal A
The 120V black Hot wire from breaker box connects to Terminal 1
The black wire going to Load (fan, light, motor) connects to terminal 2
The white wire going to Load connects to terminal A along with the Neutral
Ground wires connects to green ground screw
If your wires from breaker and wires to load are wired in reverse, the timer will turn ON the Load but the timer will not shut the circuit OFF.
To test which wire is Hot and Neutral, look at explanation at bottom of page.

240V: Let's say your Load is 240 Volts (or 220 Volts)
The clock motor is still 120V so you still need a white Neutral wire connected on Terminal A
Now you have 2 Hot wires coming from breaker box
Hot wire 1 from breaker box connects to Terminal 1
Hot wire 2 from breaker box connects to Terminal 3
Wire 1 going to Load connects to Terminal 2
Wire 2 going to Load connects to Terminal 4
Ground wires connects to green ground screw

What if you don't have a Neutral wire and you are wiring a 240V circuit?
240V circuits normally have 2 hots and a ground, but no neutral
Buy the T-104 timer
The T-104 has a 240V clock motor
Wiring for the T-104 is exactly the same as 240V wiring shown above for T103 EXCEPT there is no Neutral on Terminal A, and Terminal A is bare
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

How to test which wire is Hot
Test requires wires with live electricity >>> this is not advisable without precaution
Stand on dry boards, do not touch anything metal, wear dry clothes, do not hold screwdriver in mouth, wear gloves, tape tester leads to wood sticks so hands are away from power
Remove wires from terminals
Separate wires so they can be tested
Turn on power
Test each wire to bare ground wire
Tester lights up on Hot wire(s)
If circuit is 120V, then there is only one Hot wire
If circuit is 240V, then 2 wires will test hot to ground >> these wires will be Hots 1 & 2
Test assumes circuit breaker is functioning normally.

How do you test for neutral?
If you have 120V line with only 1 hot wire, then one of the white wires will be Neutral?
Test Hot wire to each white wire
Tester lights up on neutral

I have a honeywell thermostat model # th5220d1003-0636 & need to know what connections to make for gas forced air heat.


This is a Focus Pro 2 heat,2 cool thermostat. If you are connecting this to a single stage(1 heat) residential furnace then your connections are: At the thermostat the R and Rc therminals are internally connected so you can connect your R terminal wire from the furnace to the R terminal at the thermostat(this is your 24 volt supply for both heating and cooling. The W or W1 wire (heating) from your furnace you connect to the W1 terminal at the thermostat. The W2 wire from your furnace(if your furnace is a 2 stage furnace) you connect to the W2 terminal at the thermostat. The G wire from your furnace(indoor fan) you connect to the G terminal at the thermostat. The Y1 wire(cooling) from your furnace you connect to the Y1 terminal at the thermostat. The C wire(common or neutral) from the furnace you connect to the C terminal at the thermostat.

I have wired a new light fitting into our downstairs toilet however when I came to test it the light worked but half the other downstairs lights are now switched off when the toilet light is swithced off....


Hi
Probably put your family at risk of electricution . By connecting the live cables to earth you have effectivly made all the metal light fittings live. It is amazing that the fuse has not blown, This in itself is dangerous and you should have an electrician look at the wiring.
The correct wiring should be as follows.
Identify cables there should be 2 twin and earth (red black & copper earth) cables and 1 twin red and copper earth. (or 2 single red wires)
connect all copper earth wires suitably sheathed in green/yellow sleeving to earth lug.
Connect 2 black cables to neutral block.
Connect either single red (0r 1 of 2 reds) into live block.
connect remaining 3 reds into loop block.

Well in your case,if the central heating was working before you change the defective thermoatat.Phaps you have done the wrong connection of the thermostat,if you look well at the connection of the thermostat, how will you recognise the earth borne is that it is fixed to the body of the part,so this means that the thermostat 3 cores are (1) common,(2) normally close,(3) normally open.With a multimeter it be very easy to determine the core that you have to cannect.

Changing a room thermostat a potterton to honeywell t6360


I think I've done it - but don't take this as absolute truth.
For the Honeywell T6360B the original Potterton wiring should be rewired as follows:
Brown [Live] goes to terminal 1; Blue [neutral] goes to Terminal 2 and the yellow/green [which is not an earth but a switched live - i.e. gives live to the heating system when the thermostat clicks in] goes to terminal 3.
Obviously all done with the power isolated and when it was switched back on we had heating again :o)
It's been on over two hours now and all seems fine.
