Dimmer

Connect

⁰Features

 Deta Connect Master Dimmers can dim dimmable LED lamps.
 For two way dimming, Slave Dimmers can be hard wired to Master

Dimmers. Alternatively, Master Dimmers can be paired with Wireless
Dimmers or a Scene Setter.

 Master Dimmers can be controlled by the Connect App by pairing it

with the Connect Link hub.

It is important to install this product in accordance with the fitting
instructions below. Failure to do so may render your guarantee void.

Set-up / Linking Products

Operating

Press ‘on’ (top) button once to switch the dimmer on (blue LED indicator will
illuminate).

Press and hold the on button to raise the light level.

Press ‘off’ (bottom) button once to switch the

dimmer off (amber LED indicator will illuminate).

Press and hold to dim the light level.

Linking the Master Dimmer to Wireless Control

Press and hold both buttons simultaneously, the blue and amber LED’s will
flash alternately to signify linking mode, and then release them.

Press the button on the device to be “linked” and the
Blue LED will flash quickly to signify that the dimmer
is now linked.

Unlinking a Wireless Control

1. Press and hold both buttons simultaneously – the blue and amber LED’s

will flash alternately to signify linking mode, and then release them.
That Switch is now in linking mode.

2. Press the button on the wireless control that you want to unlink. The

amber light on the Switch will flash to confirm that the remote is now
unlinked.

Unlinking all Connected Controls

This will remove all wirelessly connected controls

1. Press and hold both buttons simultaneously – the blue and amber LED’s

will flash alternately to signify linking mode, and then release them.
That Switch is now in linking mode.

2. On the Switch, press and hold down the ‘on’ button again until the blue

and amber LEDs flash simultaneously, then tap (don’t hold) the ‘on’

button a further time; the amber LED will flash quickly to confirm that
the memory has been cleared.

Important things to consider

Adjusting the dimming range

Signal Range

• Reliable range of operation is approximately 15 metres indoors and up

to 100m outdoors using the Connect Link/WiFi-Link. This figure may
vary depending upon the environment; very thick walls, bodies of
water or large metal objects may interfere with radio range.

• If the distance between the transmitter and receiver is too great to

achieve reliable operation, the Connect Signal Booster may be used in
conjunction with this product to increase the range.

Load
ONLY Dimmable lamps can be used even if the Dimmers are used solely to

switch between the on and off states without dimming. This is because the
technology used in an electronic dimmer is fundamentally different to that
of a simple on/off switch and requires compatible lamp technology.

Compatibility

Compatibility between electronic Dimmers and LEDs can be affected if the
total circuit loading is very small. Total LED load decreases (relatively) as it is
shared between a greater number of connected Dimmers; therefore, as more
Slave Dimmers (up to 6) are added to a single circuit, it is possible that LED
performance may become less stable.

The dimming range of the dimmer can be adjusted to increase the dimming
range or prevent lamps from flickering. Ensure dimmable lamps are fitted.
Adjust the dimming range as follows:

1. Press and hold both buttons simultaneously – the blue and amber LED’s

will flash alternately to signify linking mode, and then release them.
The dimmer switch is now in linking mode.

2. Press the (top) ‘on’ button twice to enter Dimming Range Setup. The

blue LED will flash to indicate that the setup menu has been accessed.
The dimmer will automatically turn on.

3. Press the ‘off’ button to gradually reduce the minimum brightness

setting. If the lamp flickers, press the ‘on’ button until the lamp stops
flickering

4. Once the optimum level has been achieved, save the setting and leave

setup by holding the ‘on’ and ‘off’ buttons until the blue LED flashes
quickly.

Installation

Safety Instructions

 IMPORTANT: Turn off the mains electrical supply.
 This wiring accessory must be installed in accordance with the current

edition of the IEE Wiring Regulations BS 7671. If in doubt, contact a
qualified electrician.

 Be aware that existing wiring circuits are not always correctly coloured,

and that other wired connections may be present in the back box.

 CIRCUIT TESTING: This dimmer must be disconnected for insulation

resistance testing.

Installation

 Ensure that the wall (back) box has a minimum depth of 35mm.
 Remove and disconnect the existing light switch (if applicable). It may

be useful at this point to mark out or take a photograph of the
connections to the existing switch so that the correct wires can easily
be transferred to the new Dimmer. Some existing wiring configurations
can be complex so take care.

 Gently remove Dimmer front plate by inserting a screwdriver into the

bottom slot/s and lifting away from the unit as shown. See Fig.1.

 Terminate the dimmer as per the wiring diagram – see Fig.2. Ensure that

the terminals are properly tightened and that no bare wire is visible.

 Any earth wires present must be attached either to the earth terminal

located in the back box or capped with a strip connector. The Dimmers
are double insulated so are not required to be earthed directly.

 Screw the Dimmer Switch to the mounting box and ensure that the

screws are sufficiently tight to support the product, but do not over
tighten as this may cause the chassis to bend. See Fig. 1c.
Ensure that the plastic spacer is correctly aligned and that no wires are
trapped between the Dimmer Switch and the back of the back box.

 Replace the front plate – a ‘click’ sound should be heard to signify that

the plate has been correctly replaced.

2-way and Intermediate Switching

 Slave Dimmers are used to create 2-way switching and is connected to

a Master Dimmer.

 For 2-way and intermediate switching, up to six Slave Dimmers can be

connected to Master Dimmer Each Slave Dimmer can be connected

directly to the Master Dimmer, or connected to each other in a ‘daisy­chain’,

 Connections between Master and Slave Dimmers requires 3-core+earth

cable. Master and Slave Dimmers are electronic dimmer and they use
one of the conductors as a signal cable (‘S’) running between the
Dimmers (as shown on the diagram). This is an elv (extra low voltage)
only and must not be connected to 230V mains; serious damage will
occur. See Fig. 3

 The maximum cable length between Master and Slave Dimmers is

100m.

 The Connect Slave Dimmer must not be used in conjunction with a

standard light switch. This will cause damage to the Dimmer.

 Do not install and run power to a Slave Dimmer before first installing

and connecting to the corresponding Master Connect Dimmer.
Damage could be caused to the Master or Slave Dimmer.
