Heater Question

I have also seen the same mode when turning on the heater.  I think it is an additional mode.  The regular heating mode is I think 3 button presses from off.  When in the normal heating mode, 1 additional press is off.

I wish I remembered what the dealer said to me.  This affects the new RPODs only with the new thermostat.  You need to keep the setting at auto.  And when changing from heat to ac or vice versa you need to keep holding down your finger to get it to change modes.  Otherwise the ac fan and heater run at same time.  This happened to me and then I remembered something about holding it down and sure enough the ac stopped when I put on the heater.  Its a little confusing and I am sure I am not explaining it correctly but you are not alone this is a new thing that happens 

I learned the same lesson this past week and did find older forum chains that talk about the heater.  Evidently the heater only works with the gas turned on and you must have the setting on auto instead of high or low fan to avoid the AC fan turning on.  Another suggestion what that if you get a small room space heater it works just as well and you don't have to worry as much about the heater area getting too hot.  On the 178 it is underneath the bed.    Good luck and happy camping!
