1. Ensure that there is power to the boiler.

2. Remove the rear panel of the transmitter, now correctly fit the batteries (2 x1.5V
LR6/AA) into the transmitter. The transmitter will start sending signals and within 10 - 20
seconds the receiver will pick up a signal, this can be confirmed by switching on the
transmitter to create a demand and observing the LED - see Operating Mode.

3. Secure the rear panel of the transmitter to a suitable wall in the living room or hall.
Refit the transmitter in place on the rear panel.

OPERATING RANGE: Within a building - up to 20 metres. Avoid positioning large
metallic objects, including mirrors, in the line - of - sight between the transmitter and
receiver.

NOTE: These components are ‘RF Linked’ and should be fitted as a pair, if they are
not, then recommissioning will be required.

RECOMMISSIONING

Press and hold the black button on the receiver, the LED light will flash immediately.
When it flashes again 2 or 3 seconds later release the button. The receiver LED light will
remain constantly ON, to indicate that it is now waiting for a corresponding signal from
the Programmable Room Thermostat Transmitter. The receiver will remain in this mode
for 3 minutes only.

The transmitter will start sending signals and within 10 - 20 seconds the receiver will pick
up a signal, this will be confirmed by the receiver’s LED light going off. The transmitter
and receiver are now ‘linked’ so that the receiver will switch ON and OFF according to
the settings on the Programmable Room Thermostat Transmitter.
