Your text messages to the GSM should be:-

R1on this will start the FBH regardless of the outside temp
R1off will turn it off again

R2on will turn on the ATC unit
R2off Will turn off the ATC unit

ZZ will start the process of first starting the FBH. It will run for 5 minutes then the ATC will be turned on. They will both run for 20 minutes then shut down (to avoid flattening your battery.

ZS will stop the sequence.

REMEMBER, it is important that if you use R1on or R2off for testing purposes, you must turn it back off with the R1off or R2off command or it will stay on indefinately. There is no 20 min timer on these settings.

I just leave my ATC in the auto position and never turn it off anyway.
