Programming
Sensor input
BX21/BX22
(6040, 6041)
The configuration of the sensor inputs BX21 and BX22 allows more
functions in addition to the basic functions;
- None: Sensor inputs BX21/BX22 deactivated.
- Buffer tank sensor B4: Upper buffer tank sensor
- Buffer tank sensor B41: Lower buffer tank sensor
- Collector sensor B6: First solar collector sensor in a collector field.
- Domestic Hot Water sensor B31: Second Domestic Hot Water
sensor that is used for full charging for the legionella function
- Cooling liquid sensor B83: No function for AMBIFLO.
- Domestic Hot Water system circulation sensor B39: Sensor for the
reflux line of the Domestic Hot Water circulation
- Swimming pool sensor B13: Swimming pool sensor
- Solar feed sensor B63: This sensor is required for solar yield
measurements.
- Solar reflux sensor B64: This sensor is required for solar yield
measurements
- Buffer tank sensor B42: Middle buffer tank sensor
- Section feed sensor B10: Joint feed sensor for cascades
- Cascade reflux sensor B70: Joint reflux sensor for cascades
- Special temperature sensor 1,2: No function
- Domestic Hot Water sensor B3: Upper Domestic Hot Water sensor
- Hot gas sensor B81: Permanently set to BX1.
Signal logic output
UX
(6071)
The voltage signal can be inverted to be able to control also pumps or
receivers of temperature requests with inverted signal logic.
Temperature value
10 V UX
(6075)
Determines the maximum temperature request that corresponds to a
voltage 10V.
Sensor type collector
(6097)
Selects the sensor type used for measuring the collector temperature.
Correction of
collector sensor 1
(6098)
Sets the correction value for collector sensor 1.
Time constant
building
(6110)
Sets the correction value for the outside sensor.
System frost
protection
(6120)
The value set here affects the response speed of the feed target
value as a function of the building type when the outside temperature
is fluctuating.
Example values:
- 40 for buildings with thick walls or outside insulation
- 20 for normal buildings
- 10 for light buildings
