3.3 Location of the outside sensor
An outside temperature sensor is not supplied as standard with the
iSense.
You only require this sensor if you want weather-compensated control of the inside temperature.
The following guidelines apply with regard to choosing a location for an outside temperature sensor:
•
Install the outside sensor on the north or north-west side of the home, away from direct sunlight.
• The sensor must be positioned at least 2.5 metres above ground level.
• Do not install the outside sensor near windows, doors, ventilation grills, extractors, etc.
Consult the documentation for your boiler for information on connecting an outside temperature
sensor.
