The default mode of operation of the Home Thermostat is referred to as 
‘Running Mode’. This is denoted by the symbol of the running man on the 
main display. When in Running Mode, the Thermostat implements the 
pre-set heating schedule and maintains pre-set ‘on’ and ‘setback’ 
temperatures during the relevant set time periods (see programming 
section for information on how to set this).
 
If the heating is on, pressing the Standby button overrides the schedule and 
turns 

off

 the heating until the next ‘on period’. If the heating is off, pressing 

the Standby button will turn the heating on until the next ‘off period’. When 
toggling Standby, the new target temperature is briefly displayed on the 
screen in place of the current temperature. If the thermostat requires the 
heating to be turned on to achieve its new target temperature, a flame 
symbol will be displayed to indicate that it has sent a command to the 
LightwaveRF Boiler Switch to turn on the Boiler.

Holding the Standby button for a couple of seconds activates ‘Away mode’. Away 
mode also reverts to a pre-set setback temperature (see setting modes); however, 
rather than returning to the schedule at the next on/off period, the mode will 
continue to remain active until it is manually cancelled by pressing the Standby 
button. These functions can also be carried out on the LightwaveRF App.
