Will not preheat when fully charged.

Boffingham, it may seem boffo, but preheat the car on the defrost setting and you'll like the results much better. I can remove 2" of snow from the windscreen and get a toasty cabin too within 30 minutes.

Hi JRay3, unfortunately I have only a Level 1 EVSE, so it is only blowing cold air even when set to Defrost

Since the Remote can be set to control the ON-->OFF time interval (in 1/2-hour increments), you can start by trying the following approximation:
Using 120vac, you get four bars for five hours of charging
Using 240vac, you get three bars for one hour of charging
As the car ages and battery capacity is reduced, the charging time/bar is reduced.
We use the Remote on a daily basis every night, usually successfully stopping the charging at around 13 bars.

Thanks JoeS, I will give this a try.
