Time program 5 K13: The relay is controlled by the time program 5
according to the settings.
Buffer return valve Y15: This valve must be configured for the return
temperature increase/reduction or partial charging of the buffer storage
tank.
Solar pump ext exch K9: The solar circuit pump for the external heat
exchanger K9 must be set here.
Solar ctrl elem buffer K8: If several exchangers are connected, the
buffer storage tank must be set at the respective relay output and the
type of solar regulating unit must be defined under prog.no.5840.
Solar ctrl elem swi pool K18: If several exchangers are connected, the
swimming pool must be set at the respective relay output and the type of
the solar regulating unit must be defined in prog.no. 5840.
Swimming pool pump Q19: Connection of a swimming pool pump at the
input Q19 .
Cascade pump Q25: Common boiler pump for all boilers in a cascade.
St tank transfer pump Q11: The DHW storage tank can be heated by the
buffer storage tank subject to it being hot enough. This transfer is
brought about by transfer pump Q11.
DHW mixing pump Q35: Separate pump for storage circulation during
active legionella function.
DHW interm circ pump Q33: Charging pump for DHW cylinder with
external heat exchanger.
Heat request K27: Output K27 is activated as soon as a heat demand
exists in the system.
Heat circuit pump HC1 Q2/Heat circuit pump HC2 Q6: The relay is used
for actuating the heating circuit pump Q2/Q6.
DHW ctrl elem Q3: Depending on the hydraulics a connected DHW
charging pump or diverting valve.
Status output K35: The status output is operated when a command
exists from the controller to the burner control. If there is a disturbance,
which prevents the burner control from operating, the status output is
switched off.
Status information K36: The output is set when the burner is in
operation.
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.
