    You do not want to operate two heating devices from the same t-stat and you have to make certain if you decide to disconnect the t-stat you have from the furnace to connect it to the stove that it doesn't provide any voltage and only acts as a switch and that it has the ability have a range that it will not call for heat around a set point this is called a swing or span in the t-stats manual.

    The normal practice is to use separate t-stats setting the furnace one to lower than the one for the pellet stove (remember the span or swing) so it acts as a backup.

    An example t-stat for pellet stove set point 71 swing of 2 degrees turns the stove up or on at 69 and off or down at 73 in this case you set the furnace t-stat at 67 or so to act as a back up if the pellet stove goes out.
