4. Siting

• The TRT036N should be located at a position which eases wiring runs
and gives good access for programming.

• It should be mounted approximately 1.5m above floor level.

5. Installation

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 unit, by undoing the retaining screws,

and pivoting the bottom of the unit outwards. The TRT036N 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

3

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.
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 TRT036N body,
then engage the top of the TRT036N 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

not to over tighten.

7. DIP Switch Settings

• Decide whether weekday/weekend (5-2) or individual (7) day

programming is required, and set the DIP switches in the correct
position on the rear of the unit. A reset will be required after
changing the DIP switch positions.

• You can set the TRT036N to run a Pumped or Gravity system.

It is important to check which system you have before setting the DIP
switches and operation. This can also be set using the DIP switches
located on the rear of the unit.

System P is for Pumped – this will allow different programmes
for both central heating and hot water.

System G is for Gravity – hot water has to follow the central heating
programmes at all times, this will also be true when in boost
or advance modes.
