baxi combi 133HE plus ;- hot water but no heating

[kobyashimaru]

hi all,

Boiler BAxi combi 133HE PLUS
my boiler works fine when hot water is required, all the relevant lights light up and hot water is available.

however, yesterday afternoon the heating shut off and hasn't come back.....thermostat says it should be on but the boiler will not kick in??

the thermostat is a Drayton Digistat 2, all appears normal


Any ideas????
