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 switch the fan off. The output
is activated when the fan is needed; otherwise it is not activated. The
fan should be switched off as often as possible in order to minimise the
total energy consumption of the system.
Sensor input BX1 (5930), Sensor input BX2 (5931), Sensor
input BX3 (5932)
Functions in addition to the basic functions are made possible by
configuring the sensor inputs.
None: Sensor inputs deactivated.
DHW sensor B31: Lower domestic water sensor, which is used for full
charging of the Legionella function.
Collector sensor B6: First solar collector sensor in a collector field.
DHW circulation sensor B39: Sensor for DHW circulation return.
Buffer sensor B4: Upper buffer storage tank sensor.
Buffer sensor B41: Lower buffer storage tank sensor.
Common flow sensor B10: Shared flow sensor for boiler cascades or
low-loss header sensors.
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 systems.
Buffer sensor B42: Centre buffer storage tank sensor.
Common return sensor B73: Return sensor for the return diversion
function.
Cascade return sensor B70: Common return sensor for boiler cascades.
Swimming pool sensor B13: Sensor for measurement of swimming pool
temperature.
Solar flow sensor B63: This sensor is required for the solar yield
measurement.
Solar return sensor B64: This sensor is required for the solar yield
measurement.
Function input H1 (5950) Function input H4 (5970) and
Function input H5 (5977)
Notice
Not all setting options are available for all H-inputs.
None: No function.
Optg mode change HCs+DHW: Operating mode changeover for heating
circuits to reduced or protection operation (prog. no. 900, 1200, 1500)
and blocking of DHW heating if contact at Hx is closed.
Optg mode changeover HC1 to Optg mode changeover HC3: Operating
mode changeover for heating circuits to protection or reduced operation.
Important
Locking of domestic hot water charging is only possible under the
setting Optg mode change HCs+DHW.
Heat generation lock: The boiler is locked if contact at Hx is closed.
Depending on parameter 2305, the domestic hot water and consumer
circuits are blocked.
The boiler is not blocked for the following functions:
Chimney sweep function
Controller stop function
Manual mode, 0 to 10 V output request
Boiler frost-protection function
Error/alarm message: Closing the input Hx results in 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/Consumer request VK2: The set flow
temperature setpoint is activated via the connecting terminals (e.g. a
ventilation heater function for door curtain units).
