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

frost protection button for 3 seconds. When in frost

mode, the frost symbol will flash on the display.

A burner symbol is displayed when temperature

will flash on the display.
