- Solid fuel boiler pump Q10: Connection of a circulating pump for the boiler cir-
cuit for connection to a solid fuel boiler.
- Time program 5 K13: The relay will be controlled by the time program 5 accord-
ing to the settings.
- Buffer return valve Y15:This valve must be configured for return temperature in-
crease/decrease or the buffer storage tank partial charging.
- Solar pump ext exch K9:here, the solar pump external exchanger K9 must have
been set for the external heat exchange.
- Solar ctrl elem buffer K8: if several exchangers are connected, the buffer storage
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 buffer K8: if several exchangers are connected, the swimming
pool must be set at the respective relay output and the type of the solar regulat-
ing 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: Boiler pump in common for all boilers in a cascade.
- St tank transfer pump Q11: The drinking water storage can be charged from the
buffer storage, if is sufficiently hot. This transfer is carried out with the transfer
pump Q11.
- DHW mixing pump Q35: Separate pump for storage circulation during active le-
gionella function.
- DHW interm circ pump Q33: Charge pump for domestic hot water storage with
external heat exchanger.
- Heat request K27: As soon as a heat demand exists in the system, the output K27
will be activated.
- Heating circuit pump HC1 /HC2: The relay is used for actuating the heating cir-
cuit pump Q2/Q6.
- DHW controlling element Q3: Depending on the hydraulics a connected DHW
charging pump or diverting valve.
- Status output K35: The status output will be operated when a command exists
from the controller to the firing automation. If there is a disturbance, which pre-
vents the firing automation to operate, the status output will be switched off.
- 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.
