MAKING THE ELECTRICAL CONNECTIONS & FITTING THE RECEIVER
Remove

Fit the new Facia
Infill Panel
1) Remove &
Discard Bridge
Connector
2) Fit Timer
Note: The IP rating of the boiler with a plug-in accessory fitted is
IP20. Ensure siting is appropriate before installing this accessory.
1. Ensure that the electrical supply to the boiler is isolated.
2. Using a suitable flat bladed screwdriver prise the Blanking Plate
from the front left-hand side of the facia assemby.
3. Remove the two screws securing the Bridge Connector. Discard the
Connector and retain the screws.
4. Engage the male spade terminals of the Receiver in the female
connectors on the facia. Secure the Receiver with the screws
previously removed.
5. Fit the new Facia Infill Panel over the Receiver and clip into place.
6. Continue with the installation and commissioning of the appliance.
Reinstate the electrical supply to the appliance. Set the clock as
described in these instructions and according to the requirements of
the user. Instruct the user in the operation and setting of the timer.

IMPORTANT: The Receiver and Transmitter are supplied as a ‘matched pair’ and MUST be installed together. Also, in the case of replacement BOTH items must be renewed.
1. Ensure that there is power to the boiler and that the boiler is turned ON.
2. Remove the rear panel of the Programmable Room Thermostat Transmitter and, noting the polarity, fit the batteries (2 x1.5V L R6/AA) supplied. Press the Reset Button on the
Transmitter - the Transmitter will begin to communicate with the Receiver within 30 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 Indicator - see the section ‘ OPERATING MODE ’ below.
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. IMPORTANT: Avoid positioning large metallic objects, including mirrors, in the ‘line - of - sight’
between the Transmitter and Receiver as the communication between the two will be adversely affected.
NOTE: Boiler is IP20 when the receiver is fitted - this affects the positioning of the boiler in bath and shower rooms

FITTING THE PROGRAMMABLE ROOM THERMOSTAT TRANSMITTER
The Programmable Room Thermostat Transmitter has two temperature operating
levels, ‘Hi’ and ‘Lo’.
‘Hi’ Mode:This is set using the ‘Hi’ dial (5°C to 30°C) and will set the temperature to
the level desired when the property is occupied (e.g. 21°C).
‘Lo’ Mode:This is set using the ‘Lo’ dial (5°C to 15°C) and will set the temperature to
the level desired when the property is unoccupied or at night (e.g. 10°C).
To Set The Time: Slide the cover (A) off the unit. Rotate the timer clock clockwise
until the time is correct as indicated by the timer pointer.
To Set The ‘Hi’ & ‘Lo’ Central Heating Times: Move the tappets outwards for
‘Hi’ times and inwards for ‘Lo’ times. Each tappet = 15 minutes.
Summer: During the summer it is recommended that ‘Lo’ is selected using the 3
position switch.
Holiday Periods: When going on holiday set both dials to 5°C to provide frost
protection of the property.

OPERATING MODE
Receiver
If the LED is Off then the Central Heating is Off.
If the LED is On then the Central Heating is On.
If the LED is continuously flashing once every 2 seconds then the batteries in the
Programmable Room Thermostat Transmitter are low & will soon require replacement.
If the LED is continuously flashing twice every second then the batteries in the
Programmable Room Thermostat Transmitter must be replaced immediately.
Programmable Room Thermostat Transmitter
If the LED is continuously flashing YELLOW once every 2 seconds then the batteries in
the Programmable Room Thermostat Transmitter are low & will soon require
replacement. If the LED is continuously flashing RED twice every second then the
batteries in the Programmable Room Thermostat Transmitter must be replaced
immediately.
Emergency Mode
If the receiver LED is continuously flashing 2 or 3 times a second then communication
between the Receiver & Transmitter has been lost. In this instance the Receiver enters
Emergency Mode. The Central Heating will operate for 3 minutes, followed by an Off period
of 9 minutes, then 3 minutes On again, repeating this sequence until the fault has been
rectified.
The unit will enter Emergency Mode when the following occurs:-
i) Communication between the Receiver & Transmitter is lost for over an hour.
ii) The batteries have become discharged.
NOTE: When Emergency Mode is activated Baxi Group cannot be held liable for any
excess consumption of gas.
Re-establishing Communication
The communication between the Receiver & Transmitter can be re-established at any time
by pressing the Reset button on the Transmitter. This must be done every time the batteries
are renewed.
NOTE: When any of the Room Thermostat settings have been changed they will normally
be communicated to the receiver unit on the boiler within 20 seconds, but may under certain
circumstances take up to 3 minutes.
