6.3.1 Assignment of user interface/remote control unit in the software
Example: heating system with heating zone 1 and heating zone 2 (Æ page 11)
6.3.2 Control mode (outdoor temperature controlled/room influence)
The temperature of the heating water in the boiler is defined by the heating characteristics
determined in the Logamatic controls. A selection can be made whether these heating
characteristics will be influenced solely by the outdoor temperature, or by a combination of outdoor
temperature and room temperature.
• Outdoor temperature controlled: The boiler temperature calculated in the controls will be
controlled by variation in the “delayed” response to outdoor temperature in combination with
selected settings for target room temperature, offset, standard temperature and minimum
outdoor temperature. This temperature is then delivered to the radiators or radiant floor heating
by means of permanent operation of the heating zone pump. The only situations in which this
setting could result in shut-down of the heating zone pump are summer operation, night setback
(depending on the reduction mode selected) or DHW mode (only with domestic hot water
priority).
• Outdoor temperature controlled, influenced by room temperature (factory default):
this form of control works in exactly the same way as pure outdoor temperature control, except
that you can use the maximum room influence parameter to determine whether and to what
extent the room temperature should influence the heating characteristics.
The remote control unit must be installed in a reference room, so that a representative room
temperature is recorded.
The greater the parameter set, the greater the influence of the room temperature on the heating
characteristics (factory setting: 0 °F (0 °C)). This applies when the room temperature exceeds or
falls below the target room temperature. If the maximum room influence parameter is set to 0,
the heating characteristics will be controlled solely by outdoor temperature.
