1. The THINK Controller is effectively an interface which allows
the householder to programme the appliance to provide the
desired comfort levels for the central heating and hot water. It also
gives information on the appliance – error codes electrical power
generated etc.
2. Whilst the THINK Controller is on the appliance the standard
screen displays the appliance flow temperature. External
sensors/room thermostats can be connected to monitor and
control the room and domestic hot water temperatures – see
sections 10.3 to 10.11.
3. The THINK Controller may be removed from the appliance and
configured as a programmable room sensor – in which case the
standard screen displays the room temperature.
4. If the THINK Controller is to be used as a room sensor it must
be configured so that the appliance will recognise it as such.
