Resetting the thermostat (default settings)

NOTE: All parameters, except the clock (time and day), return to their default
settings when the thermostat is reset.
1. Press the Mode button until Standby appears on the screen.
2. Press the button for 6 seconds.
3. The thermostat will display rSt (reset) for 2 seconds to indicate it is reset
and will then return to normal display.

Power outage

During a power outage, the thermostat display remains lit for the first 2
minutes. During this time, the LP (low power) indicator appears and all
buttons are disabled. Then the screen turns blank. The settings are stored
in memory. When power returns, the thermostat returns to the mode of
operation preceding the power outage. If the power failure has exceeded 5
hours, the clock and date must be re-adjusted.
