Siting

Receiver

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

Installation

Receiver

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.

2. 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.

3. 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.

4. 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. 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.

6. 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.

7. Once in place, secure with the retaining screws making sure not to over tighten.

1. 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.

2. 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.

3. 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.

4. 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. 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.

6. Once in place, secure with the retaining screws making sure not to over tighten.

Connect the 230V 50Hz mains supply and load cables to the terminal block which are marked as follows;

230V 50Hz Mains Supply

230V 50Hz Mains Supply
Live Supply (Brown or Red) to      L
Neutral Supply (Blue or Black) to  N
A ‘Loop Terminal’ is provided should a 3 core cable be used

Load (Boiler)
Switch Live (Brown or Red) to  NO

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.
