Run-Back Timer
Overview
The RBT2 run back timer is a high output electronic timer which provides control
for a wide range of loads. The unit allows an appliance to be powered for a set
time period which can be adjusted by the user. A simple LED display shows the
user how much time is left to run, and its “Night Light” feature illuminates all the
LED’s when the unit is not in use, so the unit can be located in the dark. Pressing
the switch whilst the unit is operating allows the user to cancel the timing program,
and the memory function of the timer will remember the last time period selected.
To operate the unit, follow these steps:
1. Press the button to start the timing sequence - the last selected time
period will be used.
2. As the unit times out the position of the LED will change to show how
much time is left. The LED will give a warning flash when 2 minutes are
left on the timing sequence.
3. Pressing the button again during timing will turn the unit off.
4. Press and hold the button to set the desired time period (15 minutes; 30
minutes; 1 hour or 2 hours). The LED will illuminate next to the selected
time. After holding the button for a few seconds the timing will change to
the next time period available. Release the button when it illuminates next
to the desired time period — the LED will stay on the selected time.
5. When the unit has turned off, it is not necessary to select the time period
again, just press the button to repeat the previous time period.
