It wasn't until a few weeks ago that I saw the thread about putting a set back thermostat in the loop with the room temp sensor. Sounds logical. In my case I leave the room temp at about 72. At night, if I remember I turn it down to about 65, then turn it backup to 72 when I get up. If I were to put a set back thermostat in the loop (in series) with the room temp sensor and I would probably turn the set back to about 63 because it would likely take too long to heat the house up from 55 to 72 (55 being a common setback used with central heat to really conserve). I can undestand the logic for making sure the thermostat is set to be considerably higher than 72 (when I want it to hold the room temp at 72). When the set back kicks in to 63F (the series circuit is "open"), it will be just like disconnecting the room sensor (until the thermostat cools to 63F). Per the previous thread (I haven't verified this), disconnecting the room temp will essentially shut the stove down. I am a little concerned that connecting and disconnecting this sensor (i.e what the thermostat essentially does) may somehow harm the electronics in the stove. If this isn't a problem for the electronics, why hasn't Harman included this as an option? There has to be a reason, anybody have any ideas? All I can figure is; 1) opening and closing the room temp sensor circuit may cause havoc with the electronics in the stove. 2) they may be worried about issues with the thermostat and room sensor not being in the same location. If they design the setback thermostat and the room temp sensor to be in the same spot, it would obviously make it more difficult to market the ability to hide the room sensor. 3) the average Joe (me) may have problems running their stove because the setting the set back thermostat further complicates operation of the system. I can see my self getting up in the middle of the night wanting some heat during a midnight movie and turning "room temp" up so the stove will kick on (even though it was already set at 72), then being puzzled because I forgot about the hitting the "setback override". I would like to try this setback thermostat, but I don't want to chance screwing my stove up. I would likely mount the set back thermostat behind the stove (out of view) and leave the room temp sensor in it's present position (just across the room). Do any Harman techies or sales people know if this "repetitive opening and closing" of the "room temp sensor" circuit will hurt the stove?
