In Temp mode the stove adjusts its heat level to hold your set temperature. Turn on ECO and it shuts off at the set temperature and relights when the room cools. ComfortBilt notes that ECO adds igniter wear and uses more electricity, so it's best for mild days.\u003c\/p\u003e\u003ch3\u003eControls\u003c\/h3\u003e\u003cp\u003eChoose from four modes: Manual (five heat levels), Temp, Weekly (up to four on\/off periods for each day) and Thstat for a wired wall thermostat.
