4. Siting

Receiver

• The TRT047 Receiver should be mounted close to the items it will be

3

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.

Transmitter

• The TRT047N Transmitter must be sited where it will not be influenced
by heat sources, for example above a radiator or a television or
a refrigerator/freezer or in direct sunlight or subjected 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 1.5 metres above floor level.

5. Installation

Receiver

5.1 Ensure the mains supply is switched off and the circuit supply fuses are

removed or the circuit breaker turned off.

5.2 Remove the wall plate from the receiver unit, by undoing the retaining

screws, and pivoting the bottom of the unit outwards. The TRT047N
receiver body can then be lifted off.

5.3 Mark the position of the mounting holes on the wall using the wall plate

as a template. Drill out the mounting holes taking care to avoid any
joists, electrical cables or water/gas pipes that may be hidden beneath
the surface. Insert the rawl plugs into the holes.

5.4 Pass the 230V 50Hz mains supply and load cables through the opening

of the wall plate. 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.

5.5 Fix the wall plate to the wall using the correct mounting screws for the

rawl plugs installed. The retaining screws which secure the unit to the
wall plate should be at the bottom.

5.6 Terminate the cables into the terminal block ensuring correct polarity

is observed and that all bare conductors are sleeved (See section 6.
Receiver Connection Diagram). Make sure that the curved washer grips
the conductor.

5.7 To reinstall the unit onto the wall plate, first ensure the wall plate

retaining screws are loosened enough to clear the TRT047N receiver
body, then engage the top of the TRT047N receiver onto the wall plate
retaining tabs, and push firmly downwards and then upwards.
There will be some resistance from the terminals.

5.8 Once in place, secure with the retaining screws making sure

4

not to over tighten.

5.9 Remove the wall plate from the transmitter unit, by undoing the

retaining screws, and pivoting the bottom of the unit outwards.
The TRT047N transmitter body can then be lifted off.

5.10 Mark the position of the mounting holes on the wall using the wall plate

as a template. Drill out the mounting holes taking care to avoid any
joists, electrical cables or water/gas pipes that may be hidden beneath
the surface. Insert the rawl plugs into the holes.

5.11 Fix the wall plate to the wall using the correct mounting screws for the

rawl plugs installed. The retaining screws which secure the unit to the
wall plate should be at the bottom.

5.12 To insert batteries into the unit, first lower hinged flip down cover and

carefully lever the battery holder cover off. Insert the 2x AA batteries
supplied into the battery holder maintaining the correct polarity,
as shown in the base of the battery holder. Re-position the battery holder
cover and click into place.

5.13 To reinstall the unit onto the wall plate, first ensure the wall plate

retaining screws are loosened enough to clear the TRT047N transmitter
body, then engage the top of the TRT047N transmitter onto the wall

plate retaining tabs, and push firmly downwards and then upwards.
There will be some resistance from the terminals.

7. Transmitter DIP Switch Settings

• The temperature swing can be adjusted between 0.5°C and 1.0°C by

selecting the desired DIP switch position found on the rear of the unit.
We suggest using 0.5°C position unless the boiler turns ON and OFF
too rapidly. Press the reset button after changing.

• The PID ‘Proportional-Integral-Derivative’ can also be selected ON or

OFF using the DIP switches on the rear of the unit. We suggest setting
this to the ON position. As the room temperature approaches the set
temperature, the thermostat will intermittently turn the heating ON
and OFF, to help prevent temperature over-shoot.
Press the reset button after changing.

• The boiler type can be set to either 3CYC (Gas) or 6CYC (Oil),

using the DIP switches on the rear of the unit.
Press the reset button after changing.
