1. Introduction
TRT products are a cost effective
comprehensive range of thermostats and
controllers designed for internal use only.
The TRT037 is a battery powered wireless
electronic programmable room thermostat,
with 6 different temperature periods per day,
automatic summer/winter time changeover, 5
day plus 2 or individual (7) day programming,
and a frost mode. There is also the option of
optimum start and adjustable span, from 1ºC
to 0.5ºC.
The TRT037 comes in two parts - a thermostat/
transmitter which is battery powered and
totally wire-free as well as a receiver which
connects into the heating system. This eases
the installation in two ways - there is no need
to bury cable runs to the thermostat/
transmitter and the receiver can be mounted
close to the boiler and other system components.
The two parts are designed to be surface
mounted on their supplied wall plates.
The electrical supply must be isolated before
attempting to install the receiver unit.

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 boiler,
control valves and pump. It should be mounted
in a position where its control buttons and
indicator lights can be easily accessed.
3. Installation
This product must be installed in accordance with
the appropriate building and wiring regulations.
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

NL
This unit is double insulated, and hence does
not need connection to the earth. If earth
continuity is required, please use the earth
terminal on the wall plate, (see Fig. 4).
To reinstall the unit on the wall plate first ensure
the wall plate retaining screws are loosened
enough to clear the TRT037 receiver body then
engage the top of the TRT037 receiver onto the
wall plate retaining tabs (see Fig. 4), and push
firmly downwards and then inwards. There will
be some resistance from the terminals. Once in
place, secure with the retaining screws.
Finally check that the system wiring is complete
and correct.
4. Operation
Initially it is important to get the two parts
(transmitter and receiver) talking to each other.
This is best carried out by two people, one at each
of the separate locations.
Press reset on the transmitter and at the receiver
connect the mains supply to the unit. Both indicator
lights (learn/manual and output on the receiver) will
come on for around 3 seconds and then go out. Press
and hold the learn button on the receiver for around
10 seconds until the blue learn/manual light starts
flashing.
At the transmitter press and hold the select and
buttons until the flashing blue learn/manual light on
the receiver goes out. The transmitter and receiver
are now communicating. This can be confirmed by
carrying out the following:- at the transmitter press
the + button until the set temperature (identified by
momentarily pressing the + or - button) is higher
than the room temperature (normally displayed).
After a short delay the output on light on the
receiver comes on.
Now press the - button at the transmitter until the
set temperature is lower than the room temperature
and after a short delay the output light will turn off.
This proves the communication is fully functional.
There is a manual facility available at the receiver.
If the auto/manual (A/M) button is pressed the blue
learn/manual light will come on indicating the receiv-
er is in manual mode. The receiver output can now
be turned on and off using the learn button.
Programming
Decide whether weekday/weekend (5-2) or individual
(7) day programming is required and move the
appropriate jumper on the rear of the TRT037
transmitter.
The temperature span (difference between on and
off temperatures) can be adjusted between 1ºC and
0.5ºC using a jumper found on the rear of the unit.
Optimum start (switching on earlier on colder
mornings) can also be turned on or off using a
jumper on the rear of the unit.
It is important to make these decisions first,
as after any change of jumper position, reset needs
to be pressed, which will return the unit to default
time and programme.
Pressing any button illuminates the screen
automatically.
During time/date and programme setting if a button
is not pressed within 15 seconds the display will
revert to the start of the sequence.
Setting date and time of day
Open programme access flap and press reset, using a
pen or similar object. All of the screen segments will
show briefly, and then the current room temperature
will be displayed.
To programme the date and time of day, open
programme access flap, and simultaneously press
and hold both the select and set buttons for 3
seconds. The year will flash.
Use the + and - button to set the correct year.
Press select to move on to programming the month
(shown to the left), and then again to programme
the day. Press select again to
programme the hours (am/pm), and again to
programme the minutes (each time using the
+/- button to make the change). Press set to return
to operating mode.
If at any time a button is not pressed for 15
seconds, the unit will return to operating mode.
Programming temperature periods for
7 days option
Notes
1) There are no off periods with this controller.
The programming sequence is:-
Start time, temperature, second start time,
second temperature and so on. Setting
temperature to 10ºC is as close to off as can be
achieved (and for most situations will be off
unless the weather is very cold).
2) If you do not want a higher temperature period
in the middle of the day adjust the temperature
for this period downward to match those of the
proceeding and subsequent period temperatures.
3) The TRT037 comes with a factory installed
(default) programme for both 5-2 and 7 day
options which you use or modify as you wish. Just
pressing the reset button brings this programme
into operation.
The default programme for every day is as
follows:-
6:00 AM 21ºC
8:00 AM 17ºC
12:00 PM 21ºC
2:00 PM 17ºC
4:00 PM 21ºC
10:00 PM 17ºC
For both 5-2 and 7 day options.
To programme the temperature periods, press
the set button. Mon will flash. To programme
Mondays time/temperature periods press select but-
ton. Alternatively use the + and - buttons to change
the day, and then select to continue. The time will
then flash. This is the start time for the first period.
Press + or - to set the hour for the start time for
period 1. Press select to move to the minutes. Use
the + and - to set the minutes. Press select to set the
temperature for this period. Use the + or - keys to
set the desired temperature. Press select again to
programme the next time period. There are
6 time periods per day.
Once the 6 periods for Monday are
programmed, Press set button, and Monday
will start to flash. Use the + and - button to change
the day to Tuesday, and then use select to program
Tuesdays time periods and
temperatures. For 7 day programming, this will need
to be done for all 7 days. If set is pressed twice, the
unit will return to operating mode.
Omitting Days
Omitting a day can be achieved by selecting 10ºC for
every time period for that day (all times and temper-
atures must be entered).
The heating will not turn on unless the room
temperature falls below 10ºC (50ºF).
Programming temperature periods for 5-2 days
option
For 5-2 day mode, time periods and
temperatures will need to be programmed for M-F
and then for S-S. ie: only 2 sets of times need to be
programmed, not 7 (individual) sets of times.
Temperature override
In operating mode, the temperature set for the
current period can be overridden. To adjust the set
temperature, press the + or - button once. The
screen will illuminate blue while button is pressed.
Use + and - buttons to set desired temperature. If
the + or - button is held down, the display will
advance rapidly. Once the desired temperature is
set, the unit should revert to displaying the current
room temperature 5 seconds after the last button
press. The illumination will also turn off after 5
seconds. In manual mode, there will be a hand
symbol displayed on the screen. The new
temperature will remain valid until the next
programmed period starts.
A burner symbol is displayed when temperature
is below desired value, indicating that the
thermostat is calling for heat from the boiler.
Review set temperature
The set temperature can be reviewed at any time,
by a single press of the + or - button. 5 seconds after
this single button push, the unit will show the
current room temperature, and the screen
illumination will turn off.
Frost protection
Frost protection reduces the set temperature to 5ºC.
Frost protection is activated by holding down the
frost protection button for 3 seconds. When in frost
mode, the frost symbol will flash on the display.
The set temperature buttons remain non-functional
during frost mode. The unit will remain in frost
mode until the frost button is held down for a
further 3 seconds.
Battery replacement
When the battery needs replacing, a battery symbol
will flash on the display.
Sleep mode
The unit can be put into sleep mode by simultaneously
holding down the + and - buttons for 3 seconds.
Pressing any button will exit sleep mode. In sleep
mode, all outputs are suspended and the screen is
blank (useful for longer periods when the house is
unoccupied and frost protection is not required).
To clean use a dry cloth only. Do not use any
liquid cleaners.

Programming temperature periods for
7 days option
Notes
1) There are no off periods with this controller.
The programming sequence is:-
Start time, temperature, second start time,
second temperature and so on. Setting
temperature to 10ºC is as close to off as can be
achieved (and for most situations will be off
unless the weather is very cold).
2) If you do not want a higher temperature period
in the middle of the day adjust the temperature
for this period downward to match those of the
proceeding and subsequent period temperatures.
3) The TRT037 comes with a factory installed
(default) programme for both 5-2 and 7 day
options which you use or modify as you wish. Just
pressing the reset button brings this programme
into operation.
The default programme for every day is as
follows:-
6:00 AM 21ºC
8:00 AM 17ºC
12:00 PM 21ºC
2:00 PM 17ºC
4:00 PM 21ºC
10:00 PM 17ºC
For both 5-2 and 7 day options.
To programme the temperature periods, press
the set button. Mon will flash. To programme
Mondays time/temperature periods press select but-
ton. Alternatively use the + and - buttons to change
the day, and then select to continue. The time will
then flash. This is the start time for the first period.
Press + or - to set the hour for the start time for
period 1. Press select to move to the minutes. Use
the + and - to set the minutes. Press select to set the
temperature for this period. Use the + or - keys to
set the desired temperature. Press select again to
programme the next time period. There are
6 time periods per day.
Once the 6 periods for Monday are
programmed, Press set button, and Monday
will start to flash. Use the + and - button to change
the day to Tuesday, and then use select to program
Tuesdays time periods and
temperatures. For 7 day programming, this will need
to be done for all 7 days. If set is pressed twice, the
unit will return to operating mode.
Omitting Days
Omitting a day can be achieved by selecting 10ºC for
every time period for that day (all times and temper-
atures must be entered).
The heating will not turn on unless the room
temperature falls below 10ºC (50ºF).
Programming temperature periods for 5-2 days
option
For 5-2 day mode, time periods and
temperatures will need to be programmed for M-F
and then for S-S. ie: only 2 sets of times need to be
programmed, not 7 (individual) sets of times.
Temperature override
In operating mode, the temperature set for the
current period can be overridden. To adjust the set
temperature, press the + or - button once. The
screen will illuminate blue while button is pressed.
Use + and - buttons to set desired temperature. If
the + or - button is held down, the display will
advance rapidly. Once the desired temperature is
set, the unit should revert to displaying the current
room temperature 5 seconds after the last button
press. The illumination will also turn off after 5
seconds. In manual mode, there will be a hand
symbol displayed on the screen. The new
temperature will remain valid until the next
programmed period starts.
A burner symbol is displayed when temperature
is below desired value, indicating that the
thermostat is calling for heat from the boiler.
Review set temperature
The set temperature can be reviewed at any time,
by a single press of the + or - button. 5 seconds after
this single button push, the unit will show the
current room temperature, and the screen
illumination will turn off.
Frost protection
Frost protection reduces the set temperature to 5ºC.
Frost protection is activated by holding down the
frost protection button for 3 seconds. When in frost
mode, the frost symbol will flash on the display.
The set temperature buttons remain non-functional
during frost mode. The unit will remain in frost
mode until the frost button is held down for a
further 3 seconds.
Battery replacement
When the battery needs replacing, a battery symbol
will flash on the display.
Sleep mode
The unit can be put into sleep mode by simultaneously
holding down the + and - buttons for 3 seconds.
Pressing any button will exit sleep mode. In sleep
mode, all outputs are suspended and the screen is
blank (useful for longer periods when the house is
unoccupied and frost protection is not required).
To clean use a dry cloth only. Do not use any
liquid cleaners.
