4.2 Default setting
Room control
The iSense is set to room control by default. This means that the flow temperature of the
central heating water is controlled by the temperature in the room where the iSense is installed.
Weather-compensated boiler control is also possible (with outside sensor); in other words based on
the outside temperature. The controller has a programmed heating curve which determines the water
flow temperature together with the outside temperature. The heating curve must be chosen so that the
least favourable room can be efficiently heated even when the outside temperature is very low.
See paragraph 5.5 for further information about weather-compensated control.
