Device setup
Modes
Pressing the Mode button toggles between the thermostat modes. Each
mode changes the thermostats behavior. Pressing the standby button at any
time will revert back to running mode (the default operating mode).
Running mode (running man symbol): This is the standard mode of
operation. In running mode, the set temperature is governed by the heating
schedule (see next section). In a scheduled o period, the word 'standby'
will also appear at the bottom of the screen to indicate that the heating is
set to the setback (o ) temperature until the next scheduled on period.
Away mode (moon symbol): Away mode sets the heating to the
temperature specified until the next day (starting at 6 a.m.). This mode can
also be activated by holding the standby button for several seconds.
Holiday mode (aeroplane symbol): Holiday mode sets the heating to the
specified temperature for the number of days specified. The thermostat will
revert to the heating schedule after this time period.
Constant mode (sun symbol): Selecting constant mode will cause the
heating to remain at the specified temperature until cancelled. The schedule
will be ignored. The target temperature can be altered using the arrow keys.
Frost mode (snowflake symbol): This mode should be activated when the
home is unoccupied for long periods. It prevents pipes from freezing by
reverting to a low setback temperature.
