Suburban has separate set of t-stats for each heating source.
One 120V AC set for electric and one 12V DC set for Propane
Both sets have SAME preset temp settings. (Normal 130*F/Hi Temp 170*F)
Atwood use to have separate sets for electric and propane but all models since 2004 have only one set
Regardless..all were SAME preset temp settings (Normal 140*F/ECO--HI Temp 180*F)
Electric heating is slowest recovery rate
Propane can be almost twice as fast recovery rate vs electric
Propane/Electric together can be almost 1 1/2 times faster vs propane only
Controls will shut down BOTH at same temp setting and will start BOTH at same time when Normal t-stat has cooled down and CLOSES (roughly 110*F-115*F)
Caveat:
Some different preset temp Normal t-stats are available as OPTIONS
But OEM Stock are SAME settings
