Sensor inputs BX1/BX2/BX3
(5930 bis 5932)

Functions in addition to the basic functions will be possible by configuring the
sensor inputs.
-

None

: Sensor inputs deactivated.

DHW sensor B31

: second DHW sensor, which is used for through loading of the

legionella function.

Collector sensor B6

: first solar collector sensor in a collector field.

DHW circulation sensor B39

: Sensor for return line of DHW circulation.

Buffer st tank sensor B4

: lower buffer storage tank sensor.

Buffer st tank sensor B41

: centre buffer sensor.

Common flow sensor B10

: common flow sensor for boiler cascades.

Solid fuel boiler sensor B22

: Sensor for the acquisition of the temperature of a

solid fuel boiler.

DHW charging sensor B36

: DHW sensor for DHW charging system.

Buffer st tank sensor

: upper buffer storage tank sensor.

Common return sensor B73

: Return sensor for the function return diversion.

Cascade return sensor B70

: common return sensor for boiler cascades.

Swimming pool sensor B13

: Sensor for measurement of swimming pool temp.

Solar flow sensor B63

: this sensor is required for the solar usage measurement.

Solar return sensor B64

: this sensor is required for the solar usage measure-

ment.

Function inputs H1/H4/H5
(5950, 5970, 5977)

None

: No function.

Optg mode change HCs+DHW

: Changeover of the operating modes of the heat-

ing circuits to reduced operation or protecting operation (program numbers
900, 1200, 1500) and locking of domestic hot water charging in case of closed
contact at H1/H4/H5/H2.

Optg mode changeover HC1 to HC3

: Changeover of operating modes of the

heating circuits to protective operation or reduced operation.

Locking of domestic hot water charging is only possible under the setting

Optg

mode change HCs+DHW

Heat generation lock

: locking of the boiler in case of closed contact at H1/H4/

H5/H2.

Error/alarm message

: Closing the inputs H1/H2 gives a control unit-internal

fault message, which will also be signalled via a relay output, programmed as an
alarm output or in the remote management system.

Consumer request VK1/VK2

: The set flow temperature setpoint is activated via

the connecting terminals (e.g. a ventilation heater function for door curtain
units).

Note: The setpoint is set under programme number 1859/1909.

Excess heat discharge

: an active excess heat discharge enables, for example, an

external source to force the consumer (heating circuit, DHW storage tank, pump
Hx) to take up the excess heat. For each consumer it can be set by the parameter
excess temperature discharge whether the forced signal is paid attention to and
therefore should take part in the heat discharge or not.

Release swi pool solar

: This function enables the solar swimming pool heater to

be released externally (e.g. via a manual switch or the solar charging priority to
be specified as compared to the storage.

Operating level DHW/HC's

: The operating level can be set via the contact instead

of via the internal time switching program (external time switching program)

Room thermostat HC's

: With the input a room thermostat request can be gener-

ated for the set heating circuit.

DHW thermostat

: Connection of the DHW thermostat.
