Wiring Diagram for Central Heating System

[gillpeer]

I have the following system:-

Fully pumped Potterton Profile 100e boiler
Separate Honeywell motorised valves for heating and water
Grundfos Pump
Randall Timer
Satchwell room thermostat
Megaflow unvented cylinder

Can somebody send or direct me to a wiring diagram for the above type of system. Is there anything specific one has to bear in mind when connecting the above.

Thanks

use the zone valve supplied with the cylinder on the hw feed as well as the zone valve in the s plan

wiring for that is in the cylinder instructions

Take a look here to see how it fits together.

For two zone valves it will be the S-Plan.

Hi, I have a similar system. There is a Megaflo installation manual available Here http://www.ribaproductselector.com/document/pdf/3727/COL5103727/MEGAflo-Installation-Manual.aspx
However, note that depending on how much of this installation you are planning to do there is a raft of legislation that must be adhered to - it's all in the manual.

Bear in mind that the combination of copper pipes, water and 230 volt can kill people; unless you know you are competent as well as confident, you should leave it to a pro.

Can you please explain what you mean by this.

unvented cylinders require an additional zone valve that is what kev means.

My installation manual for the Profile 100e shows more than 3 wires (live, switched live etc.). Which live and neutral on the S-Plan wiring diagram relate to the wire connection in the boiler.
