Installation

• Ensure the mains supply is switched off and the circuit supply fuses are removed or the circuit breaker turned off.

• Connect the incoming 230V 50Hz supply and outgoing load cables to the relevant terminals ensuring correct polarity is observed and that all bare conductors are sleeved (see section 5. Connection Diagram).

• A front cable exit cut-out is provided with a pre-installed removable cover.

• If the front exiting cable cut-out is required:
  1. Undo the 2 fixing screws and remove the blanking plate (you can discard the blanking plate at this stage but keep the 2 fixing screws).
  2. Remove the cable grip from the accessory pack.
  3. Using the 2 fixing screws previously removed from the blanking plate, secure the load cable to the unit.

• Finally secure the unit to the back box with the fixing screws provided, forming the cables during installation to avoid any entrapment and cable damage.

Connection Diagram

The terminals are marked as follows on the rear of the boost timer;

Mains Supply
Live (Brown or Red) to L IN
Neutral (Blue or Black) to N IN
Load
Switch Live (Brown or Red) to L OUT
Neutral (Blue or Black) to N OUT

Operation

• The required boost time is selected by pressing the button marked boost, repeatedly. The LEDs adjacent to the time markers will light up in sequence, showing the selected boost period.

• The LED’s adjacent to the time markers (above the Boost button) will light up in the sequence;
  First push gives ¼ hour boost (LED opposite ¼ hour is ON)
  Second push gives ½ hour boost (LED opposite ½ hour is ON)
  Third push gives 1 hour boost (LED opposite 1 hour is ON)
  Fourth push gives 2 hour boost (LED opposite 2 hour is ON)
  Fifth push returns to zero boost (all LEDs are OFF).

• Once the boost selected is underway, the LEDs will go out sequentially, indicating the approximate boost time remaining.
  The LED which is about to go out will flash when there is less than 2 minutes remaining of that period.
  Example: 2 hour boost has been set, all LEDs are on;
  After 58 minutes the 2 hour LED will flash for two minutes, and then go out indicating 1 hour remaining.
  After a further 28 minutes, the 1 hour LED will flash for two minutes, and then go out indicating ½ hour remaining.
  After a further 13 minutes, the ½ hour LED will flash for two minutes, and then go out indicating 15 minutes remaining.
  After a further 13 minutes the ¼ hour LED will flash for two minutes, and then go out, indicating that the boost period has finished.

• In this way the user has an approximate guide to the remaining duration of the boost.

Stopping or Increasing Boost

• During the first 15 seconds of activating the boost timer, it can be stopped by pressing the boost button repeatedly until all the LEDs are off.
• It can also be stopped during this time period, by holding down the boost button until all the LEDs are off.
• After the first 15 seconds of activation, the boost may be cancelled with a single push of the boost button.
• The Boost periods can only be increased during the first 15 seconds of activation. At all other times, the boost must be cancelled first, and the required boost periods re-entered.
• If the boost button is pushed and held down, the LEDs will cycle upwards with 1 second between each change, in sequence ¼, ½, 1, 2, OFF.
