For the last year I have been trying to get the right combination on my central heating wiring. If you can help please feel free.
I have central heating and hot water.I changed my pump and mid pos valve 6 months ago,and committed the cardinal sin of not writing down the wiring pos. My heating will come on when I turn the l522 programmer on and god love it it will stay on,but the acl rts1 room stat will not turn it off,for some reason its always calling for heat.my latest wiring config looks like this.
TERMINAL STRIP
NO1 connection empty
NO2 neutrals
NO3 Earths
NO4 Heating on(from controller)/Room stat live
NO5 white(mid pos)/Room stat calling
NO6 Brown Hcl3 Tank stat/Hw calling
NO7 Blk (tank stat) &Grey (mid pos)/Yellow(heating off)programmer
NO8 Blue(tank stat) &orange(mid pos)/Yellow (sl from boiler)
NO9 Brown( Pump)/blue from boiler
Controller has neutral-live hw off Yellow-ch off(no wire connected)
Hw on-ch on.
I have looked at the Y plan diagram all seems correct.The only thing puzzling me is the SL comes from the boiler and the blue comes from terminal 7 of the boiler and makes its merry way upstairs in the cable that has Ch on also.
If you haven't give up the ghost yet.
The boiler has connections to the programmer 5 wires lead out.
brown connects to the live terminal,blue to neutral earth to earth,the SL which is black&white goes into a floating plastic terminal sending its signal up the yellow wire.
and theblack from the boiler goes into the same floating terminal block next to the SL sending its signal up the blue wire.
So after all that can you work out if I have made a mistake.
If this helps with hot water only on the temp either in the boiler or the tank stat stops the burner,but the pump will keep running.
when the programmer goes live the blue and yellow from boiler are both live.
