One of these wires is contains permanent live, neutral and earth. The other wil be heating on and hot water on, the earth on this wire will probably not be used.
you will have to trace the wiring back or test it!! Be carefull!!

How do I fix central heating


The first thing you need to substantiate is the fact that there is enough water in the system. It will be a closed loop system requiring approximately 10 psi/ floor. (Only a rule of thumb). Usually when one protion of the system works and the other does not, it is an issue of water quantity available to circulate through the combination of loops. If you have to add water, you will probably have to purge air from the highest points in the system. Even if there is an "Airtrol" fitted in the bottom of the expansion tank, bleeding the high points will eliminate air quicker.

The hot water portion of the loop should only be going through a heat exchanger that transfers the loop temp to the domestic water circuit and the three way valve is probably a 'mixing valve' utilized to maintain a certain loop temperature on the primary loop.

Disregard wire colors. Instead wire by terminal designation. In other words :
Wire on "R" Terminal on old thermostat to "R" Terminal on new thermostat no matter the color.

Hi - after a power cut the clock on the display of C27 timer has not come on so there is no power going to it. I cannot find a separate fuse going into it - does the Honeywell C27 have the fuse inside it....


Press the SET and CH buttons at the same time. The 2 outside buttons. This will restore the factory presets. Then she should be able to program the timer.

I have an intermatic C8865 timer. i want to wire it into an EFM model AF150-1 coal stoker furnace, because the fire goes down to far inbetween actual times heat is called for. also have main switch for...


Intermatic C8865 timer is a 5-hour cycle timer that repeats same cycle each 5 hour period.
This timer has 120Volt clock motor and is 120V timer.
Timer has NO and NC terminals.
NO terminal turns ON when timer turns ON
NC terminals is ON all the time, except when timer turns ON. At this point NC terminal turns OFF.

You have 3 things: 120V timer, 120V honeywell transformer, 120V stoker motor/fan
The transformer needs to be ON at all times.
The stoker motor is going to turn ON when the cycle timer turns ON.

You have 120V cable with black wire, white wire (and bare ground, which connects to green ground screw and to other bare grounds and won't be discussed further)

Black wire is hot
White wire is neutral

Black wire connects to 'Switch common terminal' on timer.
Same wire also connects to black wire on Honeywell transformer.

White wire connects to 'Clock terminal' on timer
Same wire connects to white wire on Honeywell transformer and to white wire on Stoker motor.
So all the white wires are connected together.

Last wire is black wire to stoker motor.
This wire connects to NO terminals on timer.

Here is drawing.

Clock doesn't work


The wiring diagram for that timer is somewhat misleading. The 120 volt clock timer motor is connected internally to the "A" (neutral) terminal and the #3 terminal. The "A" (neutral) terminal is to the immediate left of the #1 terminal.
Here's how to do the wiring for your use, (assuming a 120 volt supply circuit and a 120 volt lighting or other load):
Connect the incoming power (line) black wire to terminal # 3. Connect the incoming (neutral) white wire to terminal "A".
Connect the outgoing (load) black wire to terminal # 4.
Connect the outgoing (neutral) white wire to terminal "A".
