Run-Back Timer
Overview
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 startthe LED will stay on next to the se­lected 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.
