Battery Status; Reset Button; Sleep Mode - Salus RT500ROF Instruction Manual

OTHER FUNCTIONS AND CONTROLS
Backlight
The backlight of the RT500 is switched on automatically whenever any of the
keys are pressed. The backlight will remain illuminated for a few 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 battery voltage is low.

Battery Status

The RT500 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.
If the LED on the One Touch Override front panel is dim or does not light it
means the batteries are low or discharged - you should replace the batteries
as soon as possible.

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 for a few seconds, the
RT500 will enter SLEEP mode. In this mode, all the RT500 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 RT500 will be turned off immediately.
Press any key to wake up the RT500 and exit SLEEP mode.
