Wiring a thermostats for solid fuel boiler

[GrahamStirling]

Hello.

I have just installed a complete vented wet central heating system. The boiler is a solid fuel stove with a back boiler with a gravity fed hot water circuit and a pumped central heating circuit.

I would like to control the pump with a room thermostat, timeclock and 2 pipe thermostats, 1 with a override "off" at 45 degs and one with an override "on" at 90 degs.

Could someone please help me with a wiring diagram as i am struggling to get my head round how to wire it all up.

Thanks in advance.

Controlling the pump with a room stat is not the best idea.
The pump needs to dump heat when the boiler is up to temperature and should not be interlocked by a room stat.
What type of stove do you have?

Thanks.

It's a sumo stove built by dowling stoves.

The gravity side has an open rad. All the other rads (on the pumped side) have thermostic valves.

I want the room stat to control the pump only when the gravity side is between 45 and 90 degs. The pipe stats will override outside this temp range to stop condesation at the low end and stop overheating at the high end.

Only prob is that i'm not sure how to wire everything up.

thanks again, Graham

My system is similar to this http://www.soliftec.com/CentralHeating.pdf but mine has a heat sink on the gravity side (a rad in the bathroom).

There's a diagram in here http://www.hunterstoves.co.uk/Assets/Current_Instructions/Herald 80B CE vII Instructions V.05.08.pdf.
Looks pretty straightforward, terminals 1 & 2 on each device would be to normally open contacts. Stat might come with changeover contacts but just ignore the extra terminal for normally closed.

Brilliant, thanks. G
