Customer asked me to wire up heating system with
Oil boiler
3 Port Motorised valve
Stat on Water Tank
No stat on Central heating
Then to wire in control to automaticaly bring in pump when log burner is lit
So oil boiler wired up to three port valve in usual way all works fine
So how to get log burner to operate Pump
I am thinking if I put a pipestat on Flow pipe from log burner to control pump
If I wire the pipestat as follows I think it will do the Job
N/C terminal to the pump output from the boiler
N/O terminal to the permanant live
COM terminal to the Pump
So in operation if oil boiler is turned on pump is operated via N/C terminal
Pipework heats Up and Pipestat switches from N/C to Normaly open feeding pump with 230v
Boiler turns off and Mid position valve returns to middle position but pump carries on running until pipework has cooled down enough for the pipestat to return to its normally off position. (bit like a pump overrun)
If Log burner is lit heat in flow pipe operates pipestat and pump is switched on.
This is how I think it needs to be wired. Any comments from anybody who has done this type of system before of has knowledge of the correct way
Hope my explanaton makes sence and thankyou for any helpful coments.
