Siting

Receiver

The TRT037N 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 TRT037N 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

Ensure the mains supply is switched off and the circuit supply fuses are removed or the circuit breaker turned off.
Remove the wall plate from the receiver unit, by undoing the retaining screws, and pivoting the bottom of the unit outwards. The TRT037N receiver body can then be lifted off.
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.
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.
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.
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.
To reinstall the unit onto the wall plate, first ensure the wall plate retaining screws are loosened enough to clear the TRT037N receiver body, then engage the top of the TRT037N receiver onto the wall plate retaining tabs, and push firmly downwards and then upwards.
There will be some resistance from the terminals.
Once in place, secure with the retaining screws making sure not to over tighten.

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.
To insert batteries into the unit, access the battery compartment located on the left side/rear of the unit. Use a small flat head screwdriver and release the lug and lever out the battery compartment. Insert the 2 x AA batteries (supplied) maintaining the correct polarity, as shown in the base of the battery compartment. Push the battery compartment back into place until clicks shut.

Connection Diagram

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

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. A reset will be required after changing the DIP switch positions.
The OST `Optimal Start Time’ can also be selected ON or OFF using the DIP switches on the rear of the unit. When set to the ON position, the heating will turn on 20 minutes earlier, for every 1°c below your chosen set point. A reset will be required after changing the DIP switch positions.

TRT037N Rear of Transmitter

Pairing the Devices

Programming Time/Temperature Periods

Note:

There are no OFF periods with this controller. As soon as a Start time begins, heat will be demanded until the temperature reaches/falls to the selected set point, then it will move on to the next Start time/temperature period, and so on. The closest you can get to turning the TRT037N programmable thermostat OFF, will be to set the selected period(s) to 10°C, this way the heating will not turn ON unless the temperature drops below these set points.
If you do not want a higher temperature period in the middle off the day, adjust the temperature for this period downward, to match those of the proceeding and subsequent period temperatures.
There are 6 time/temperature controlled periods, and the default programme for every day is as follows;
06:00AM 21°C
08:00AM 18°C
12:00PM 21°C
02:00PM 18°C
04:00PM 21°C
10:00PM 18°C
