Temperature overshooting

We have a Valiant ecotec+. We tried switching the heating back on ready for winter, set to 19, but when I woke in the night it was 24. We've tried to 2 hours to reset and resynch but it keeps heating up again. We have now turned it completely off. We had this issue last year too but it seemed easier to resolve. Any suggestions?
