4. Siting

• The TRT030DN 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

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 TRT030DN 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 Carefully remove the plastic terminal cover. 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.

Reposition the plastic terminal cover and push into place.

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

retaining screws are loosened enough to clear the TRT030DN body,

then engage the top of the TRT030DN 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

• 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.

• 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.

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

using the DIP switches on the rear of the unit.

8.Operation

• Restore mains to the unit after making sure to check all system wiring

is complete, and after you have selected the desired DIP switch settings.

• The current room temperature will appear on the display.

• Use the dial adjuster to set the desired temperature.

The screen will illuminate at the same time.

• Once you have reached the desired set temperature, it will flash

on the screen for approximately 3 seconds before returning to display

the current room temperature. The back light will turn off.

• The Blue LED output indicator is lit when the room temperature is below

the desired value, indicating that the thermostat is calling for heat from

the boiler, and the heating symbol will appear on the display.

• Once the room reached the desired temperature the LED turns OFF

and the TRT030DN ceases to call for heat from the boiler.

The heating symbol will disappear.
