Setting the control strategy

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 (therefore not measured). The outside
temperature, the heat up rate and the cooling rate influence this.
The degree of shift is influenced by the RT effect setting. ¼

The advantage of this control is that desired changes in room
temperature can be anticipated quickly. Without the controller having
to be located in the reference room.
The boiler will remain off for longer for desired downward changes in
room temperature. This is good for the energy consumption.
5 OTC/RTC ECO: Weather-compensated with comfort function
The OTC control strategy is used where the desired room
temperature is higher than the night temperature. Night temperature
is 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.
6 RTC + Limit
Room control with heating curve as limit. Same as control strategy
1, but the heating curve is used as max boiler temperature. (External
sensor required).
The RTC control does not have its full temperature control
range available due to the heating curve limit. As a result,
it may take longer to heat up.
The controller lets you use the room control and/or weather-
compensated control strategies in various ways. You can select one
of the controls, described in paragraph 5.1 via: Menu > Settings >
System > Control settings.
