Installation

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

• Remove the two bezel fixing screws, and remove bezel from timer module and wall plate.

• Ease the module forward without disconnecting, so you have access to the wall plate and loosen the screws on the terminal block for both supply and load cables.

• Ensuring that the free terminals on the wall plate are at the top, terminate the 230V 50Hz supply and load cables to the terminal block ensuring correct polarity is observed and that all bare conductors are sleeved.
  Please note the connections are marked on the rear side of the wall plate (see section 5. Connection Diagram).

• Fit the wall mounting screws through the wall plate and into the wall box threaded holes, and tighten until the wall plate is firmly fastened.

• Re-position the module back into place ensuring the time indicator is on the bottom right hand side, and the locating holes on the timer are set correctly on the pegs on  the back plate.

• Re-fit the bezel over the timer module, and secure to the wall plate with the two fixing screws previously removed.

6. Operation

• Decide what times you would like the time switch to switch ON and OFF.
• Push the segments down for the duration of an ON period.
• Pull the segments up for the duration of an OFF period.
• The minimum switching interval is 15 minutes, and this can be increased in 15 minute steps.
• Set the correct time of day by rotating the dial clockwise until the correct time is indicated by the triangular pointer.

Points to note;

• As the dial is rotated there will be an increased resistance to turning as ON/OFF periods are passed.
• The segment dial can be turned whilst the time controller is operating.
• In the case of a power failure, re-adjust the time controller to the correct time of day by turning the dial in a clockwise direction until the correct time is indicated by the pointer.

Permanent Override

• The main slider on the timer can be set to permanent ON by sliding it to the left.
  This will align the arrow head to the 1 symbol, and the green flag will now be fully visible on the right.

• For normal automatic mode, the main slider can be set to the middle position with the arrow head pointing at the timer symbol.

• The main slider on the timer can be set to permanent OFF by sliding it to the right. This will align the arrow head to the 0 symbol, and the red flag will now be fully visible on the left.
