Time constant building
(6110)
The value set here influences the reaction speed of the nominal flow value in case
of fluctuating outside temperatures as a function of the building design.
Beispielwerte (siehe auch Schnellabsenkung Prog.-Nr. 780, ... ):
- 40 for buildings with thick walls or outer insulation.
- 20 For buildings of normal building design.
- 10 For buildings of light building design.
Central setp compensation
(6117)
The central setpoint lead monitors the heat generator setpoint to the required
central flow temperature. With the setting the maximum corrector is restricted,
even if a large adaptation is required.
System Frost Protection
(6120)
The heating circuit pump will be activated by the outside temperature without
heat request If the outside temperature reaches the lower setpoint of -4°C,the
heating circuit pump will be activated. If the outside temperature is between -5°C
and +1.5°C, the pump will be activated every 6 hours for 10 minutes. When rea-
ching the upper limit of 1.5°C, the pump will be switched off.
Saving sensors
(6200)
Sensor statuses can be stored under programme number 6200. This happens au-
tomatically; however, after changing the plant (removal of a sensor) the state at
the sensor terminals must be stored new.
Control numbers generator
1/storage/heating circuit
(6212, 6213, 6215, 6217)
The basic device generates a control number for identification of the plant sche-
me, which is composed of the numbers compiled in Tab. 7 (Page 111)
