Hello , I am still learning systems on our 2014 Sundance XLT 245RL that we purchased in the fall . Yesterday while hooked to shore power I decided to check to see if the furnace works . Opened one propane tank valve and set the thermostat to furnace low . It doesn't have a furnace high setting . Anyway after a few seconds the furnace came on but so did the roof AC . It was 68 degrees outside and I set the thermostat at about 75 to make sure the furnace came on .
It only took about 30 seconds for heat to come out of the floor/wall registers . The roof unit stayed on . It didn't sound or feel like the AC compressor was coming on so maybe just the fan came on ? Is it possible the roof AC fan is wired to come on in furnace mode ? Being a 30 amp camper I wouldn't think it has electric heat strips but I don't know that for sure . I ran it for 5 minutes and didn't feel any heat coming out of the ceiling AC vents . A few weeks ago during g a warm spell I did run the AC and it cooled fine . Our maiden camping trip is April 14 - 16 and just trying to be prepared . Any advice on the furnace/roof fan coming on is appreciated .
