10.16 Outside sensor unit installation procedure
1. Outside sensor location: The outside sensor carton is illustrated with Suitable locations and advises against locations which are likely to give poor / false readings.
2. Avoid south facing walls; preferably choose a west to north facing location.
3. The ideal height for the sensor is at approximately half the height of the living space of the dwelling and no less than 2.5m off the ground.
4. Avoid locating the sensor close to the flue terminal where the flue plume could heat the sensor and cause the appliance to switch off prematurely.
5. Two core "bell wire" is suitable.
6. When correctly connected and once the 'Save sensor' procedure has been done (See Section 11.4), the outside temperature and icon will be display on the THINK
Controller (See Section 10.12 and Fig 42).

10.17 Wireless Installation
1. If a wireless system is being installed then communication must be establish between the various RF components and the special RF 5 LED Receiver which contains the
transceiver for the appliance. Each kit as outlined in section 6.7 includes installation instructions. An overview is given below: ­
2. In the wireless 5 LED kit (part no. 720026201) the wireless 5 LED Receiver and the cradle are prebound but subsequent cradles holding THINK Controller for second
heating circuits must be connected or 'bound' to the 5 LED transceiver.
3. The available RF component transmitters are: ­
The cradle ­ enables direct connection with the THINK Controller.
The outside sensor transmitter.
The repeater unit ­ enables components to be positioned in otherwise dead areas to the RF 5 LED Receiver. The repeater unit requires a mains supply.
4. Observe the same considerations for locating the wireless THINK Controller as the wired room sensor.
5. To bind the units together use the following procedures.
6. Each THINK Controller must be allocated to the correct heat circuit i.e. room unit 1/room unit 2/operator unit as described in Section 10.13 and 11.3 paragraph k, this can
be done on the appliance or later when in the RF cradle.
7. Switch the appliance on and insert the RF 5 LED Receiver into either the appliance or an off appliance wired cradle.
8. If the RF Cradle and RF 5LED Receiver came boxed together then they will be prebound. Insert the 3xAA batteries into the RF cradle and insert the THINK Controller, 'data
update' will show and then the percentage progress will show if the THINK Controller is new to the appliance. After a short while 'Operator unit ready' then the standard
screen will appear. The THINK Controller can now be used as an RF programmable room sensor.
9. If Error 83 appears move the THINK Controller in the RF cradle closer to the RF 5 LED Receiver. If distance/line of sight is not the problem the RF components will need
to be connected or 'bound' together using the following procedure: ­
10. Press and hold the reset button on the RF 5 LED Receiver around 10 seconds until the second and fourth LEDS are lit.
11. Press the menu button to enter the user menu and then press and hold the easy menu and menu buttons until the other access levels appear. Scroll down to the
commissioning option and select by pressing the Selector Button. Scroll down to the wireless options and select to enter this list as shown opposite.
12. Select parameter 120, scroll to 'yes'. 'Wait' will appear until the unit is bound. As each unit is bound they will appear in the list above as being 'in operation'. If a unit does
not appear, move it to a different location and then choose and confirm test mode. This will initiate a series of 24 test signals which are shown along the top of the display
and sent back and shown on a line underneath. Move the unit to a location where at least 20 of these signals are echoed back. If few or no signals are received it will be
necessary to use a repeater unit to relay the signal.
NOTE: The THINK Controller refresh rate will be slower than when it is mounted directly on the appliance or in a wired cradle.
IMPORTANT: Before running the appliance ensure parameter 5700 has been set according to the type of system installed.
See sections 10.4 to 10.11 for system types and section 11.3.k for the change procedure.

11.0 Commissioning
11.1 Preliminary Electrical Checks
1. Reference should be made to BS:EN 12828, 14336 and 5449 Section 5 when commissioning the boiler.
2. Prior to commissioning the boiler preliminary electrical system checks should be carried out.
3. Remove the outercase, the bottom panel and lower the control tray to gain access to the electrical connections (see section 10.1).
4. These should be performed using a suitable meter, and include checks for Earth Continuity, Resistance to Earth, Earth Loop Impedance, Short Circuit and Polarity.
5. At the time of commissioning, complete all relevant sections of the Benchmark Checklist at the rear of this publication.
11.2 Commissioning the Boiler
NOTE: The transit brackets ­ 3 off must only be removed just before commissioning the appliance.
1. The engine is held securely for transit by 3 brackets (Figs. 48 & 49). To ensure that all 3 brackets are removed before firing the appliance, two security measures must be
overcome:
a) Firstly all 3 brackets are wired together. Remove the bottom (left and right hand) brackets first (Fig. 49) by removing the screws from underneath the engine and then undo the
M6 screws securing the brackets to the back of the appliance. Disengage the brackets and withdraw.
Remove the top centre bracket by removing the three M5 screws (8mm spanner) (Fig. 48).
NOTE: Please retain the screws and brackets in case re­siting the appliance is necessary.
The center bracket should also be refitted to protect the engine head during servicing.
