Air Conditioner Thermostat question

The COST to use the 12 to 5 button adapter is almost the same as buying the 12 button Tstat since you have just 1 Roof top unit. So buy the 12 button. The 12 button does have more bells and whistles like you can program multiple sequences like a home tstat. Now, IF you need under storage heat from the LP furnace, you will HAVE to use the LP furnace mode on the system. Dometic HP's, you are either on HP or LP and cannot be automatic between the 2. UNLESS, the outside temp falls below 36 degrees and you are in HP mode. Once the outside temp falls below 36 degrees, the HP shuts off and the LP furnace will heat until the outside is above 36 degrees again. Which means you have freeze protection since the LP furnace takes over below 36 degrees. Dry Camping or not, you can ALWAYS select LP furnace mode to heat. The 12 button system is plug and play. All you have to do is set the DIP switches on the 12 button control board up in the new Penguin. You would set the Furnace DIP--ON. Doug
