PRODUCT DATA AND INSTALLATION SHEET
RBT1 RUN-BACK TIMER
DESCRIPTION AND OPERATION
The RBT1 run back timer is a high output electronic timer which provides control
for a wide range of loads. Its powerful 20A output makes it particularly suitable
for the control of immersion heaters. The unit allows an appliance to be powered
for a set time period which can be adjusted by the user. A simple display shows
the user how much time is left to run. An ON/OFF switch allows the user to cancel the timing program whilst a memory remembers the last timing sequence
selected.
To operate the unit, follow these steps:
1. Press and release the TIME button to select the desired time period. The
LED will flash next to the selected time.
2. Press the ON/OFF button to start—the LED will stay on next to the se-
lected time.
3. As the unit times out the position of the LED will drop down to show how
much time is left.
4. Pressing the ON/OFF button during timing will turn the unit off.
5. At any stage during timing, pressing the TIME button will set a new time
period.
6. When the unit has turned off, it is not necessary to select the time period
again, just press the ON/OFF to repeat the previous time period.
INSTALLATION
Warning. This device works at mains potential. Be sure to take care when
working with electricity.
1. Make sure the load is connected and in working order.
2. If fitting to a metal back box ensure that top and bottom lugs are
removed.
3. Isolate the mains supply to the circuit at the main consumer unit.
4. Connect the controller via the terminal block. Live supply to the L
terminal, the load to the LIVE OUT terminal and neutral to the N
terminal.
5. Screw the unit to the wall and switch the mains supply back on at
the distribution board.
