3. Installation
This product must be installed in accordance with
the appropriate building and wiring regulations.
2. Siting
The TRT037 transmitter must be sited where it
would not be influenced by heat sources, for
example, above a radiator or television or
refrigerator/freezer, or in direct sunlight or
subject to draughts. The product requires air
circulation, so do not position above or below
shelving or other wall mounted obstacles.
It should be mounted approximately 1.5m
above floor level.
The TRT037 receiver should be mounted close
to the items it will be controlling i.e. boiler,
control valves and pump. It should be mounted
in a position where its control buttons and
indicator lights can be easily accessed.
To reinstall the unit on the wall plate first ensure
the wall plate retaining screws are loosened
enough to clear the TRT037 transmitter body then
engage the top of the TRT037 transmitter onto
the wall plate retaining tabs (see Fig. 5), and push
firmly downwards and then inwards. Once in
place, secure with the retaining screws.
Receiver
Isolate 230VAC mains supply. Incoming and outgoing
wires should be 1.5 sq mm.
Remove wall plate from unit, by undoing retaining
screws (see Fig. 4), and pivoting the bottom of the
wall plate outwards. The TRT037 receiver can then
be lifted off.
Thread the incoming wires through the hole in the
wall plate, and fix wall plate securely to the wall,
using screws (and wall plugs if necessary) provided.
The screws which secure the TRT037 receiver to
the wall plate should point downwards.
Allow sufficient excess cable to wire up the unit,
but not too much to make it difficult to close the
unit onto the wall plate.
Connect the conductors to the relevant terminals,
according to the wiring diagram below (Fig. 7).
Ensure that the curved brass washers grip the
conductors.
In all cases if there is a doubt as to how to
proceed with an installation consult a qualified
electrician, your local authority’s building
control department or the Timeguard helpline
(020 8450 0515).
The TRT037 transmitter and receiver are
designed to be surface mounted on their
supplied wall plates.
Always isolate the mains supply before
removing the receiver from its wall plate.
Transmitter
Lever the battery holder out using a large flat
blade screwdriver or large coin (see Fig. 6) and
then pull out fully.
Insert the 2 x AA alkaline batteries supplied into
the battery holder maintaining the correct polarity
as shown in the base of the battery holder.
Push the battery holder back into place until it
clicks shut.
Remove wall plate from unit, by undoing
retaining screws (see Fig. 5), and pivoting the
bottom of the wall plate outwards. The TRT037
transmitter can then be lifted off.
Fix wall plate securely to the wall, using screws
(and wall plugs if necessary) provided. The screws
which secure the TRT037 transmitter to the wall
plate should point downwards.
