Not sure what you mean by "dialed in".
Most Entegra coaches are equipped with three AC/Heat Pump units on the roof. If you have your AC units turned on and operational, then you can have them either producing cool air conditioning to cool your coach, or you can have them producing warm air from the heat pumps. The heat pumps should supply good warm air down to an outside temperature of about 43-45 degrees. At that point, they will not provide warm air. You need to show those units what you want.... by turning on them to heat, or to cool, or to auto.
Now, on Entegra coaches, other heat is either provided by the AquaHot burning diesel, or the AquaHot burning propane. Many Aspire coaches are equipped with propane AquaHots. All Anthem and Cornerstone coaches have diesel fired AquaHots. You get heat from the AquaHots only if you have the word Diesel turned on or illuminated on a VegaTouch system. Ive never owned a propane equipped Entegra coach so dont know the signage for propane. However, it should be obvious what fuel source you have.... propane must have a separate propane tank which is usually in the front compartment. Diesel comes from the same diesel tank as your Cummins engine.
Now, you can either get heat from the AquaHot by the unit providing heated water to 3 or 4 floor vents which have grates in front, and small heat exchangers behind them with muffin fans behind the heat exchangers. The fans will start and stop and blow warm out out of the vents into the coach. Alternately, you may have the option of floor heat, and instead of heated air being produced, only the warm water is pumped through piping in the floor and heat is generated by the floor picking up the heat from the tubing and heating the floor.
So, tell me more about what you are dealing with and I will try to help we will try to help you more. You say you have a 19 Entegra but not the model (Aspire, Anthem, Cornerstone). It would be good to enter that into your signature.
