Receiver - installation
The receiver is intended for wall-mounting in a clean, dry environment. It is a class II control,
suitable for ambient temperature from 0 to 50
0
C. It has 60mm wall-fixing centres which are com-
patible with standard pattress 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 flat-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 connections
(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 connection is needed. Use a separate single
screw terminal block to provide earth continuity 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
until the housing clicks into place.
Power-up the control set and complete the setting up procedure.
After fitting batteries to the transmitter; fitting the receiver to the wall and installing wired connections appropri-
ate for the heating 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 transmitter 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 left) should appear in the display, and within a further ~10 seconds, the
receiver Heating on LED should illuminate. There is an audible click as the switching relay operates. The heating
appliance should now be running. The receiver can also be operated manually by briefly pressing the centre
override button. Note that if the transmitter is left in demand mode after the receiver is manually overridden to
off (and vice-versa), the transmitter will re-assert control and switch back on approximately 10 minutes later.
The transmitter 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 transmitter 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, briefly press the receiver ON/OFF button.
- the demand symbol is visible in the transmitter’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 setting a de-
mand temperature.
Before connecting the receiver to the boiler, make sure that you have followed the boiler external thermostat
connection instructions. A mains connection to a volt-free terminal could damage the boiler circuitry.
