6.3.2 Control mode (outside temp. contr./room influence)
The temperature of the heating water in the boiler is defined by the heating curve in the Logamatic
control unit. You can select whether this heating curve will be influenced solely by the outside
temperature, or by a mixture of outside temperature and room temperature.
•
outside temp. contr.
: If this setting is entered, the boiler temperature calculated in the control
unit will be regulated by variation in the adjusted outside temperature in combination with
selected settings for set room temperature, 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 temp. contr. with room temperature hook-up
(factory setting): this form of control
functions like a pure weather-compensated control with the difference that parameter
maximum
room influence
enables the determination whether and to what extent the room temperature
can influence 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 higher the parameter is set, the higher the proportion of the room temperature effect on the
heating curve (factory 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.
