Away - Set to the time you leave home and the temperature you want while you are away (usually an energy-saving level). Home - Set to the time you return home and the temperature you want during the evening, until bedtime. Sleep - Set to the time you go to bed and the temperature you want overnight (usually an energy-saving level).

M36240 M362415 M35968 Adaptive Intelligent Recovery Over time, the T6 Pro Thermostat “learns” how long it takes your system to reach the temperature you want. It turns on the heating or cooling system earlier to make sure you’re comfortable at the time you expect. Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump). When the safe wait time has elapsed, the message stops flashing and the compressor turns on. Built-in compressor protection Message flashes until safe restart time has elapsed.

If your thermostat was not wired to run on AC power, then batteries are required. Install fresh batteries immediately when the low battery icon appears. The icon appears about two months before the batteries are depleted. Even if the low battery icon does not appear, you should replace batteries once a year, or before leaving home for more than a month. If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory, and do not require battery power.
