Status information K36: The output is set when the burner is in opera­
tion.
Flue gas damper K37: This function activates the flue gas damper con­
trol. 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) und Sensor
input BX3 (5932)
Functions in addition to the basic functions are made possible by configur­
ing the sensor inputs.
None: Sensor inputs deactivated.
Hot water sensor B31: Second DHW sensor, which is used for full
charging of the legionella function.
Collector sensor B6: First solar collector sensor in a collector field.
HW circulation sensor B39: Sensor for DHW circulation return.
Buffer sensor B4: Lower buffer storage tank sensor.
Buffer sensor B41: Centre buffer storage tank sensor.
Common flow sensor B10: Common flow sensor for boiler cascades.
Solid fuel boiler sensor B22: Sensor for the acquisition of the tempera­
ture of a solid fuel boiler.
HW charging sensor B36: DHW sensor for DHW charging systems.
Buffer sensor B42: Upper buffer storage tank sensor.
Common return sensor B73: Return sensor for the return diversion func­
tion.
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 usage meas­
urement.
Solar return sensor B64: This sensor is required for the solar usage
measurement.
Function input H1 (5950) Function input H4 (5970) and
Function input H5 (5977)
None: No function.
Optg mode change CHs+HW: Changeover of the operating modes of
the heating circuits to reduced or protection operation (prog.nos. 900,
1200, 1500) and locking of domestic hot water charging in case of
closed contact at H1/H4/H5/H2.
Optg mode changeover CH1 up to Optg mode changeover CH3: Oper­
ating mode changeover for heating circuits to protection or reduced op­
eration.
Note
Locking of domestic hot water charging is only possible under the
setting Optg mode change CHs+HW.
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-in­
ternal fault message, which will also be signalled via a relay output, pro­
grammed as an alarm output or in the remote management system.
Consumer request VK1/Consumer request VK2: The set flow tempera­
ture setpoint is activated via the connecting terminals (e.g. a ventilation
heater function for door curtain units).
Note
The setpoint is set under prog.no. 1859/1909.
Release swimpool source htg: activation triggers heating of the swim­
ming pool by the heat source.
Excess heat discharge: Active excess heat discharge enables, for ex­
ample, an external source to force consumers (heating circuit, DHW
storage tank, Hx pump) to draw off excess heat with a signal. For each
