Adjustments are not needed in the room where the controller
is located. Any radiator valves present in the reference room
must be fully opened.
4 OTC + C-RT: Weather-compensated with comfort
function
The basis of this control strategy is the same as weather-
compensated control. The heating curve must therefore be
correctly entered. The heating curve is also shifted on the
basis of a room temperature that is calculated (and therefore
not measured). The outside temperature, the "heat up rate"
and the "cooling rate" influence this. The degree of shift is
also influenced by the RT effect setting, see paragraph 11.3.
The advantage of this control is that desired room
temperature changes can be anticipated quickly, without the
controller having to be located in the reference room.
The boiler will remain off for longer for desired room
temperature changes downwards, and this is good for the
energy consumption.
5 OTC/RTC eco: Weather-compensated daytime control
and room control at night
The "OTC" control strategy is used where the desired
room temperature is higher than the night temperature
(temperature set via Menu > Program > Night temp.). The
relevant settings must therefore be set. The "RTC" control
strategy is used where the desired room temperature is the
same as or lower than the "night temperature".
The controller must then be located in a room which is
representative for room temperature measurement during
the night.
This control strategy prevents the boiler from being switched
on unnecessarily during the night.
11.2 Setting the control strategy
The iSense lets you use the room control and/or weather-
compensated control strategies in various ways. You select
one of the controls described in paragraph 11.1 via Menu >
Settings > System > Control settings.
11.3 Specific settings for weather-compensated control
If you have opted for a weather-compensated control strategy,
a number of extra settings are available via Menu > Settings >
System > OTC settings.

Heating curve:
-
Base outside: outside temperature base point
-
Base flowtemp: flow temperature base point
-
Climate outside: outside temperature climate point
-
Climate flowtemp: flow temperature climate point
-
Curvature: degree of curvature of the heating curve,
depending on your central heating system. Select the
relevant type of heaters: underfloor heating, radiators or
convectors.
This will provide more comfort early and late in the year.
