Thanks, I have no access to such a compressor only one of those 12v car tyre compressors.
When I attach the hose to the Flow pipe with everything closed water pressure initially caused air pressure in the un-bled system to rise.
The joints can then be tested with soap solution as you would with...
Originally we had a back boiler which has been ripped out and a wood burning stove installed in its place. The system was full of black sludge.
I have, Replaced all of the radiators with new including TRVs.
Flushed out the copper pipes of the system prior to the connection of the new rads.
The...
Connections...
Only two pairs of live and neutral out from the programmer.
There is a live feed out from Term 3 (HW on)
another from Term 4 (CH on) all neutrals connect to 'N'
From cold both CH & HW the system run heating the water and providing CH.
Everything gets up to temperature...
I have replaced the RWB2 with the ST9420c. Nothing now works?
The connections should be the same, but there is no CH or HW?
With CH & HW set to auto, once or cont, CH & HW indicators are on but there is no voltage to either terminal 3 or 4.
There is permanent 240v to terminals 1 & 2...
I bit the bullet and ordered one...

Will see if its a straight replacement?
However what happens to the old stat in the hall, should O remove it?
Or turn it fully up? If I remove it will...
Thanks Hugh
I will add that to my list of possible replacements,
I can do some miner wiring modifications if required for programmers that
are not identical. I will replace the back plate with new one anyway.
I do like the idea of a Wireless programmable stat and think its worth the...
Any comments on this one as a replacement for the RWB2?
Will it work on the same wires that are connected in the RWB2?

Any other compatible wireless or non wireless?
Thank you for the prompt replies.
Regarding the gas fire part of the back boiler system, the gas fire would be used in milder parts of the year with main CH turned off. I will look into location of any pump?
I have just moved into a house with a L&G RWB2 Programmer controlling a Glow-Worm Majorca 246 or 246'N' Combined Central Heating Boiler and Space Heater. With Gas Fire to the front. (C.1977).
There is a Satchwell Thermostat in the hall, which as a cost saving we do not heat. There is a Hall...
