Hi,
Can anyone please advise?
I have a very old system that i am trying to nurse through winter until we get an extension built and convert to a W/B combi boiler. At the moment, we have an old cast iron boiler (ideal i think) with a separate grundfos pump. The programmer is a Danfoss Randall 102E but this has gone kaput! The slider switch contacts are all very worn and only intermittantly making contact. I have a spare Landis & Staefa RWB9 programmer that i want to replace the Danfoss with but are unsure of the wiring. The info' i have is:
Danfoss 102E 1 = DHW
2 = HTG
3 = COM
4 = EARTH
5 = NEUTRAL
6 = LIVE
Landis & Staefa RWB9 Position 1 = NEUTRAL
Position 2 = LIVE
1 = DHW
2 = OFF
3 = ON
4 = CH
Can anybody tell me how to wire up?
Regards,
