10.13 To Configure the THINK Controller as a Room
Sensor (cont)
3. Press the menu button repeatedly until the standard screen is
available. The Programmable Room Unit symbol should be shown
on the screen if the THINK Controller has been configured
correctly, see Fig. 42.
4. If a second THINK Controller is to be used to control either a
second heating circuit or to remain on the appliance then the
parameter settings are slightly altered, see Section 11.3 paragraph
k and Table 2.
5. To complete the reconfiguring the main PCB must be
rebooted with the information from the THINK Controller, so
switch off the appliance and then repower after 10 seconds. The
THINK Controller will now act as a programmable room sensor
when mounted into a wall cradle.
6. The THINK Controller's can be replaced on the appliance at
any time but to avoid conflict and Error 84 address collision
problems, parameter 40 must be reconfigured back to
'Operator Unit 1'.
7. When an THINK Controller is mounted in a wall cradle, the
5 LED Receiver fills the space on the appliance. It acts as an
indicator see fig. 43 and enables user resets to be carried out as
they cannot be performed remotely.
10.14 To Install the 5 LED Receiver and THINK
Controller
1. Isolate the appliance.
2. Remove the 5-LED Receiver from the wall cradle (as supplied).
3. Connect the wire terminals between the room unit wall cradle
and the appliance controls installation area, using wire suitable for
12v. (<200m)
4. Install the wall cradle in a suitable room or hall way. (see
Section 10.15)
5. Make sure the wall cradle is not in a position where it can be
accidently knocked or tampered with.
6. Remove the THINK Controller from the appliance and place it
in the wall cradle.
7. Place the 5-LED Receiver onto the appliance.
8. Switch on the appliance.
9. If the THINK Controller has not been configured as a Room
Sensor correctly, you may see error 84: BSB collision. If this does
happen, repeat from Section 10.13 paragraph 2 while the
THINK Controller is on the wall cradle. Once the parameters
have been checked down power the appliance for 10 seconds
and then switch the appliance back on.
