6.4.2 Control mode (outside temperature compensated/room influence)

In the Logamatic control unit the heating curve specifies the temperature of the heating water in the
boiler. It can be selected whether this heating curve is influenced solely by the outside temperature,
or whether a mix from the characteristics of the outside temperature and the room temperature
define the heating curve.
• Outside temperature compensated: with this setting a boiler temperature, which is
calculated in the control unit, is controlled by means of a change in the adjusted outside
temperature combined with selected settings for room target value, offset, design temperature
and minimum outside temperature. This temperature is then delivered to the radiators or
underfloor heating system by means of permanent operation of the heating circuit pump.
The only circumstances in which this setting can result in the heating circuit pump being
switched off are summer mode, night setback (subject to the selected setback mode) or DHW
mode (only with DHW priority).
• Outside temperature compensated with the influence of room temperature (basic
setting): this type of control works exactly as the pure weather compensated control, but with the
difference that, by means of the parameters for maximum room influence, it can be defined
whether, and to what degree, the room temperature has an influence on the heating curve.
The programming unit/remote control must be installed in a reference room to ensure that a
representative room temperature is captured.
The larger the parameter is set, the larger is the proportion of the room temperature on the design
formation of the heating curve (basic setting 0 Kelvin) This applies when the room temperature
exceeds or falls below the set room temperature. If the maximum room influence parameter
is set to 0, the heating characteristics will be controlled solely by outside temperature.
