Retrofit kit? Dometic says I have to buy a new unit to upgrade the thermostat.
For the past 4 years ALL Penguins come with the 12 button CCC Tstat control board. If you buy a NEW Penguin and want to use the Old 5 button CCC Tstat you have to purchase a 12 button to 5 button upper control board kit. The 5 button upper board will not communicate with a 12 button wall tstat. The 12 button upper control board that comes with the New Penguin's will not communicate with a older 5 button CCC wall tstat. So, for the same amount of money you can purchase a 12 button Tstat to go with the NEW Penguin for about the same money to buy the 12 to 5 retrofit kit. The reason they make the 12 to 5 kit is if you have more than 1 roof air (Penguin) and you do not want to replace BOTH upper units AND buy a new Tstat. Also, the NEW 12 button HP Penguins have 3 fan speeds and the old 5 button only had 2 fan speeds. By upgrading to the new Penguin HP and 12 button tstat, you get 3 fan speeds. Doug
