Weird Boiler/Heating issue

    I've a Potterton promax 24 Combi Boiler which is about 4 years old. We turned the heating on for the first time this week since before summer. It's behaving really weird in that I can only get either the upstairs or downstairs to work but not both.

    There are termostats both up and downstairs. If I want to get the upstairs rads to heat I need to turn the heat on downstairs first, then turn upstairs on and downstairs off. When I just turn upstairs on the boiler doesn't kick in and the rads don't heat. Likewise once upstairs is actually on if I turn downstairs on the rads downstairs don't heat up.

    I did notice the boiler pressure was pretty low (just below 1) so I released the valve to increase this to nearer 2 but that made no difference. I've tried bleeding the rads etc. but that hasn't helped.

    When the rads are on they heat perfectly so I don't think it's an air lock or anything like that.

    Any ideas?

    Thanks.
