Battery Heating

[DBedford]

We own a ZS facelift TLR, iSmart suggests in the schedule I use the battery heater 1 hr before I use the car (which is great if you use the car each day at the same time, otherwise not!).

My question is setting the heating, should the car be plugged in and charging or not as I have tried to set the heating, when the car is not plugged in, to start at 07:00 and it appears to save ok, but going back into iSmart at its back to 1pm as shown.
Any ideas please, thanks.

Check that it actually says "success" when savings. It sometimes says "failed", and you have to save again when it usually says "success" second time around.

Thank you, Yes has said 'success' each time I've tried to set a time, but bounces back to 1pm each time.
