The TGBT4 is a boost timer giving a range of boost times from 1/4hr to 2hrs
covering the majority of requirements for heating, ventilation and lighting
(a light switch may be replaced by this unit if a neutral is available).

The unit fits on a single gang wall box, flush or surface, 25mm deep and
above.

It can be instantly cancelled or reset and the 1/4hr LED flashes a warning of
time out.

A blanking plate can be removed to allow an appliance cord to outlet from
the lower front.

TGBT4 Rear Connections

The unit is designed to replace an existing single gang connection unit,
socket outlet or fixed appliance outlet. The unit is capable of forming part of
a ring main (the terminals can accept 2 x 2.5mm sq. cables) or terminating a
spur off the ring main. The unit requires a minimum depth of 25mm within
the box.

Ensure that the wiring is adequate for the load to be carried. Connect
incoming and outgoing cables to the relevant terminals. Secure the unit to
the back box with the 3.5mm screws provided forming the cables during
installation to avoid entrapment and cable damage.

Use the earth terminal in the back box for earth continuity if required.
If installed into a metal back box, earthing of the back box is required.

There is a removable cable blank to cover the front cable exit if this feature is
not required. If front exiting cable is required use the cable clamp supplied to
secure the outgoing cable.

3. Operation

The required boost time is selected by pressing the button marked Boost
repeatedly. The LED’s adjacent to the time markers (above the Boost button)
will light up in the sequence:-

First push gives 1/4hr boost (LED opposite 1/4 is on)

Second push gives 1/2hr boost (LED’s opposite 1/4 and 1/2 are on)

Third push gives 1hr boost (LED’s opposite 1/4, 1/2 and 1 are on)

Fourth push gives 2hr boost (LED’s opposite 1/4, 1/2, 1 and 2 are on)

Fifth push returns to zero boost (all LED’s out)

Once the boost selected is underway the LED’s will go out sequentially
indicating the approximate boost time remaining.

Example:- 2hr boost has been set.

After 1hr the 2hr LED will go out indicating 1hr remaining.

After a further 1/2hr the 1hr LED will go out indicating 1/2hr remaining.

After a further 1/4hr the 1/2hr LED will go out indicating 1/4hr remaining.

The 1/4hr LED begins to flash when there is less than 1 minute remaining.

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

Stopping or Increasing Boost

The boost may be stopped at any time by pressing the Boost button
repeatedly until all the LED’s are extinguished.

The boost period may be increased at any time by pressing the Boost button
until the required time LED is lit. In which case the indicated boost time will
start from when the Boost button was pressed.

If the button is pressed and then held the LED’s will cycle upwards with 1
second between each change. It will go in the sequence 1/4, 1/2, 1, 2, OFF,
1/4, 1/2 etc.
