Whatever temperature you set will be maintained 24 hours a day, until you manually change it, or press RUN to cancel "Hold" and resume the program schedule.

Built-in compressor protection

This feature helps prevent damage to the compressor in your air conditioning or heat pump system.
Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait 5 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.

Early Start

Early Start: This feature allows the heating or cooling to turn on before the program start time, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.
The next time period is displayed when the system is activated before a scheduled time period.

Battery replacement

Pull at bottom to remove thermostat from wallplate.

Install two fresh AAA batteries when Lo Batt flashes on the screen. Lo Batt appears for 60 days before the batteries are depleted.
Replace batteries once a year, or when you will be away for more than a month.
Most settings are stored in non-volatile (permanent) memory. Only the clock and the day must be set after you replace the batteries.
Set the System switch to Off before removing the batteries. Otherwise, the heating/cooling system could remain activated even when batteries are removed.
