6.3.2 Control mode (outside temp. controlled / room influence)
The temperature of the heating water in the boiler is defined by the heating characteristics
determined in the Logamatic controller. A selection can be made whether these heating
characteristics will be influenced solely by the outside temperature, or by a mixture of out-
side temperature and room temperature.
– Outside temp. controlled: If this setting is entered, the boiler temperature calculated
in the controller will be regulated by variation in the "delayed" response to outside tem-
perature in combination with selected settings for target room temperature, offset,
standard temperature and minimum outside temperature. This temperature is then
delivered to the radiators or underfloor heating by means of permanent operation of the
heating circuit pump.
The only situations in which this setting could result in shut-down of the heating circuit
pump are summer operation, night setback (depending on the reduction mode
selected) or DHW mode (only with domestic hot water priority).
– Outside temp. controlled, influenced by room temperature (factory setting): this
form of control works in exactly the same way as pure outside 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 charac-
teristics.
The programming unit / remote control unit must be installed in a reference room, so
that a representative room temperature can be recorded.
The greater the parameter set, the greater the influence of the room temperature on the
heating characteristics (factory setting: 3 Kelvin). This applies when the room temper-

Setting: Which operating unit is
assigned to the heating circuit? Effect
A HC 1 = RC35, HC 2 = RC35
(see Fig. 2, 1 on page 10)
Same room temperatures for HC 1 and HC 2
B HC 1 = RC35, HC 2 = none
(see Fig. 2, 1 on page 10)
Room temperatures for HC 1 and HC 2 can be
set separately
C HC 1 = RC20, HC 2 = RC35
(see Fig. 2, 2 on page 10)
Room temperatures for HC 1 and HC 2 can be
set separately;
room temperatures for HC 1 are set on RC20
