I am updating my heating system from gravity fed to fully pumped (S-Plan). My extension kit is quite old and only has a single button. How do I make the change?

    Look at page 13. Try setting it for an s plan system and see if that makes a difference.

    That's great but, sonce it is currently configured for a gravity fed system, it turns the hot water on even if I only want the central heating on

    @steve2 I had the same issue when I set up my system in January. I thought I had a gravity fed system, the instructions were misleading. I have a Y system (boiler and separate cold water tank and a immersion heater with its own themostat). I changed it from S plan to Y plan and it worked, so no more having the hot water coming on at the same time as the heating.
