With this parameter the function for the modulating pumps is specified.
- None: No output P1 exists.
- Boiler pump Q1: the connected pump is used for recirculation of the boiler wa-
ter.
- DHW pump Q3: Control element for drinking water storage.
- DHW interm circ pump Q33: Charge pump for domestic hot water storage with
external heat exchanger.
- Heat circuit pump HC1 Q2: the heat circuit pump HC1 will be activated.
- Heating circuit pump HC2 Q6: the heat circuit pump HC2 will be activated.
- Heating circuit pump HC3 Q20:the heat circuit pump HC3 will be activated.
- Collector pump Q5: a circulation pump for the collector circuit is required for
connection of a solar collector.
- Solar pump ext exch K9: if several exchangers are connected, the buffer storage
must be set at the respective relay output. and the type of the solar regulating
unit must be defined in prog.no. 5840.
- Solar pump swi pool K18: if several exchangers are connected, the the swim-
ming pool must be set at the respective relay output. and the type of the solar
regulating unit must be defined in prog.no. 5840.
Selection of used sensor types for measurement of the collector temperature.
Setting a correction value for collector sensor 1.
Setting a correction value for outside sensor.
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.
possible values (see also Quick setback prog.-no. 780, ... ):
- 40 for buildings with thick walls or outer insulation.
- 20 For buildings of normal building design.
- 10 For buildings of light building design.
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.
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 reach-
ing the upper limit of 1.5°C, the pump will be switched off.
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.
The basic device generates a control number for identification of the plant
scheme, which is composed of the numbers compiled in Tab. 9 (Page 106)
