TFC Boiler Plus Optimum Vibe User manual

OPTIMUM VIBE PROGRAMMABLE THERMOSTAT - INSTALLATION INSTRUCTIONS
The OPTIMUM VIBE is a radio frequency programmable thermostat. It MUST be installed by a qualied person, in
accordance with best pracse and current IEE wiring regulaons. Before programming, complete all set-up instrucons.
The control set - when congured for T.P.I. control - meets the UK Government BEIS Department’s criteria for Class
IV control, contribung 2% towards energy eciency of the system.
The transmier is baery-powered (2 x AAA alkaline); the receiver is mains-powered, with volt-free switching.
The control set uses the license - free 868 MHz radio band to communicate between transmier and receiver
Installaon procedure: transmier and receiver posioning
The receiver will normally be located close to the heat source, and should derive it’s mains supply from the same
circuit that powers the heater / boiler. However avoid locang it directly next to the boiler’s case - see 1 below.
The transmier should be located within the property bearing in mind the following requirements:
The transmier has an on-board temperature sensor, which it uses to detect ambient temperature, and calculates
whether to send a demand or no-demand signal to the receiver. The transmier should be located in a main living
area, where it is visible, has a free air-ow and is not unduly inuenced by draughts or extraneous heat sources:
radiator / direct sunlight / lamp— please refer to the diagrams below:
1 The radio-frequency signal range is 20 to 30 metres in convenonal brick / mber / le structures. Note that me-
tallic materials such as reinforced concrete and foil-backed plasterboard will reduce or in some cases block the ra-
dio frequency signals. It is best to posion both transmier and receiver so that they are not close to large metallic
objects, and bear in mind that mirrors reect radio waves in the same way they reect light.
Transmier - installaon
Place 2 x AAA alkaline baeries in the baery compartment at the back of the transmier; ensure correct polarity.
Set the me and day: Aer inserng baeries, the transmier will jump to me-seng mode, or during normal
operaon, touch SET for ve seconds, change the minutes, touch SET, change the hours, touch SET, change the
day, touch SET. Then touch the ON/OFF icon to put in run mode. Full set-up can be completed later.
The transmier can be wall-mounted, or placed on a table-top or counter, using the back-plate or the stand includ-
ed in the carton. If wall-mounng, x the back-plate to the wall observing the UP ↑ ↑ marks, align the top two
recesses on the back of the transmier, to the top two lugs on the back-plate, then rotate downwards to ‘click’ the
other two lugs in place. Reverse this procedure to remove the transmier from the back-plate. Note that - if you
hold the transmier for longer than a few seconds, it will start to detect your body temperature, rather than the
ambient room temperature, and this will aect the calculaon of demand / no demand for heat. Replace the
transmier onto the back-plate or stand so that it will again start to detect the ambient room temperature.

Transmier Receiver

Receiver - installaon
The receiver is intended for wall-mounng in a clean, dry environment. It is a class II control,
suitable for ambient temperature from 0 to 500C. It has 60mm wall-xing centres which are com-
pable with standard paress boxes. A back-plate channel is provided if wiring has to be surface-run.
The receiver requires a 230 volt live and neutral supply, and controls a volt-free changeover switch.
Separate the receiver top cover from the base by gently levering the cover upwards with a at-bladed screwdriver
placed into the two slots on the underside.
Fit the receiver to the wall, and connect to the terminals provided. See the wiring diagrams below:

Wiring for volt-free switching:
Connect 230V AC Live and Neutral to L & N
Connect the volt-free boiler connecons
(SW1 / SW2) to COM & N O (common and
normally open)
Do not connect anything to terminal N C
Wiring for mains switching:
Connect 230V AC Live and Neutral to L & N
Fit a short link wire between L & COM
Connect the (230V mains) switched live to N O
Do not connect anything to terminal N C
The VIBE receiver is a double-insulated Class II control. No earth connecon is needed. Use a separate single
screw terminal block to provide earth connuity if required. Clip the cover on top of the installed receiver: align the
two lugs on the upper edge of the cover with the tabs on the base, and pivot downwards, applying light pressure
unl the housing clicks into place.
Power-up the control set and complete the seng up procedure.
Aer ng baeries to the transmier; ng the receiver to the wall and installing wired connecons appropri-
ate for the heang appliance, switch on the mains supply to the receiver. The green Power L E D should be visi-
ble on the receiver. Now check the receiver response: keep the transmier approximately 1 to 2 metres from the
receiver, and touch the UP arrow to raise the SET temperature above the measured ROOM temperature. Within
2 or 3 seconds the demand symbol (see le) should appear in the display, and within a further ~10 seconds, the
receiver Heang on LED should illuminate. There is an audible click as the switching relay operates. The heang
appliance should now be running. The receiver can also be operated manually by briey pressing the centre
override buon. Note that if the transmier is le in demand mode aer the receiver is manually overridden to
o (and vice-versa), the transmier will re-assert control and switch back on approximately 10 minutes later.
The transmier and receiver control set is pre-commissioned at the factory. Refreshing of the RF link is possible
(see Refresh RF Link on page 4), but this should not be necessary. The transmier and receiver should communi-
cate as soon as they are both powered-up. If there is a problem, make sure that:
- the green Power LED on the receiver is illuminated. If not, check the mains supply and ensure the receiver is on.
If necessary, briey press the receiver ON/OFF buon.
- the demand symbol is visible in the transmier’s LCD. If not, increase the SET temperature to at least one de-
gree above the ROOM temperature. The demand symbol should be visible within three seconds of seng a de-
mand temperature.
Before connecng the receiver to the boiler, make sure that you have followed the boiler external thermostat
connecon instrucons. A mains connecon to a volt-free terminal could damage the boiler circuitry.

To open the conguraon menu, rst touch the transmier ON/OFF buon to turn the display o (touch
any buon to ‘wake-up’ the transmier, then touch the ON/OFF buon to turn o), then touch the SET and
UP buons at the same me for 5 seconds:
You will be viewing the rst of 15 opons which can be congured to adjust the operaon of the OPTIMUM
VIBE, to best suit the installaon and the user’s requirements.
Touch the UP or DOWN arrows to adjust the parameter, and touch SET to move sequenally through the
opons. Changes will be saved by pressing the ON/OFF buon. If no buon is touched for 10 seconds, the
display will ‘me-out’, but your changes will sll be saved.

Refresh RF link
Press and hold the centre override buon on the receiver unl the Heang on LED ashes rapidly. Release the
override buon—the LED must be ashing. Turn o the transmier by touching the ON/OFF icon. The display
will go blank. Now touch the SET icon for 5 seconds. A unique pre-set four-character code will show in the top
le of the display. Release and then briey touch the SET icon once more. The receiver LED will stop ashing and
the RF link has been refreshed. Quit back to normal running mode by touching the ON/OFF icon.
Receiver ON / OFF
You can turn o the receiver. The receiver’s output will switch o, and it will stop responding to the transmier.
Transmier ON/OFF
You can save baery power on the transmier, by touching the ON/OFF icon. The transmier is switched o and
will stop sending control signals; the receiver will remain in it’s current state (ON or OFF).
