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.

Receiver Wiring Diagram
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 button for
1 second, keeping it held down, press and hold the
‘ ’ button so they are both held down together.
Hold them both down 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

receiver 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
button. 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 temperatures 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. i.e.: 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
