Hi Please try this if it doesn't work you will unfortunately need to replace the thermostat.

You can try a reset this way. Take the batteries out for a few min and also put them in backwards(that will clear the memory) then replace them the correct way:-) Sometimes helps .

Good Luck

Tech Michael
