1. Introduction

TRT products are a cost effective comprehensive
range of thermostats and controllers designed
for internal use only.
The TRT036 is a two channel programmer
dedicated to central heating and hot water,
with automatic summer/winter time
changeover (which can be cancelled), 5 day
plus 2 or 7 (individual) day programming,
pumped or gravity fed system, holiday mode,
boost function, advance to next programme
and permanent on/off over ride. There are
three timed control periods per day.
The unit is fitted with a factory installed
battery which gives up to 24 hours back up
of time, date and programmes in the event
of a mains failure.
It is designed to be surface mounted on its
supplied wall plate.
The electrical supply must be isolated before
removing the thermostat from the wall plate.

2. Siting

The TRT036 should be located at a position
which eases wiring runs and gives good access

for programming. It should be mounted

approximately 1.5m above floor level.

3. Installation

This product should be installed by a qualified

installer to current installation standards.

If in any doubt contact the Timeguard Helpline
020 8450 0515.

Always isolate the mains supply before

removing the unit from its wall plate.

The TRT036 is designed to be surface mounted
on the supplied wall plate.

Isolate 230VAC mains supply.

Incoming and outgoing cable should be 1.5mm sq.

Programmers allow you to set ‘On’ and ‘Off’

time periods. Some models switch the central
heating and domestic hot water on and off at
the same time, while others allow the domestic
hot water and heating to come on and go off
at different times.
Set the ‘On’ and ‘Off’ time periods to suit your
own lifestyle. On some programmers you must

also set whether you want the heating and
hot water to run continuously, run under the
chosen ‘On’ and ‘Off’ heating periods, or
be permanently off.

The time on the programmer must be correct.

Some types have to be adjusted in spring and
autumn at the changes between Greenwich
Mean Time and British Summer Time.

You may be able to temporarily adjust the

heating programme, for example, ‘Override’,

‘Advance’ or ‘Boost’. These are explained in

the manufacturer’s instructions.

The heating will not work if the room thermostat

has switched the heating off. And, if you have a
hot-water cylinder, the water heating will not
work if the cylinder thermostat detects that the

hot water has reached the correct temperature.

Remove wall plate from unit, by undoing

retaining screws, and pivoting the bottom of the
unit outwards. The unit can then be lifted off.

Pass incoming wires through opening in wall plate,

and fix wall plate securely to the wall, using screws

provided. The screws which secure the product 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 to the wall plate.

Connect the conductors to the relevant
terminal, according to the wiring diagram

on the wall plate (or below). Ensure that

the curved brass washer grips the conductor.
