Mend Protherm 80e Boiler Central Heating Faulty

Protherm 80e?

my boiler is playing up , hot water working fine, but the central heating has gone weird, it gets up to 64 degrees then cuts out then it kicks back in after a minute or two, then just keeps repeating this, cutting out then firing up like a yo yo , pressure is ok . any ideas.
