OTHER FUNCTIONS AND CONTROLS
Backlight
The backlight of the RT500RF is switched on automatically whenever any of
the keys are pressed. The backlight will remain illuminated for approximately
5 seconds after the last key press, except if you are changing settings within
the Clock, Programme or Temporary Override modes – in this case, the
backlight will remain illuminated throughout the setting change process.
The backlight will not illuminate if the RT500RF battery is low.
Battery Status
The RT500RF checks the battery voltage frequently during normal
operation. If the battery voltage is sensed as being low (this is normally
when the battery voltage falls to a level of around 2.6V), the low battery
indicator will be displayed on the screen.
Although the programmable thermostat will continue to operate normally
at this stage, you should replace the batteries as soon as possible to prevent
any possible operating problems.

Reset Button

The Reset Button is provided as a way to restore the programmable
thermostat to its default factory settings. Pressing this button will delete any
previously entered settings.
Sleep Mode
By pressing both the UP and DOWN keys together, the RT500RF will enter
SLEEP mode. In this mode, all the RT500RF functions will be paused to save
battery power, with the exception of the clock which will continue to run in
the background.
While in SLEEP mode:
• The LCD display will be blank.
• All output from the Control Unit will be turned off immediately.
Press any key to wake up the RT500RF and cancel SLEEP mode.
