-
Status information K36
: The output is set, when the burner operates.
-
Flue gas damper K37
: This function activates the flue gas damper control. If the
flue gas damper control is activated the burner will only start operating, when
the flue gas damper is open.
-
Fan shutdown K38
: This output serves to stop the fan. The output is activated,
when the fan is needed; otherwise it is not activated. The fan should be switch-
ed off as often as possible, to minimize the total energy consumption of the sys-
tem.
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.
