Relay output QX21 module 1 (7301), Relay output QX22
module 1 (7302), Relay output QX23 module 1 (7303), Relay
output QX21 module 2 (7376), Relay output QX22 module 2
(7377), Relay output QX23 module 2 (7378), Relay output QX21
module 3 (7451), Relay output QX22 module 3 (7452) and Relay
output QX23 module 3 (7453)
None: Relay outputs deactivated.
Circulating pump Circulating pump Q4: The connected pump serves as
DHW-circulating pump (see programme number 1660).
El imm heater DHW K6: With the connected immersion heater, the DHW
can be charged according to the operating side DHW storage operating
line immersion heater.
Important
The operating mode is set under prog.no. 5060.
Collector pump Q5: Connection of a circulating pump in case of solar
collector use.
Cons circuit pump VK1 Q15/Cons circuit pump VK2 Q18: Connection of
a pump at the input Q15/18 for an additional consumer, which is
requested via an Hx-input.
Boiler pump Q1: the connected pump is used for recirculation of the
boiler water.
Alarm output K10: in case of a fault, this will be signalled by the alarm
relay. The contact is closed with the delay time selected under prog. no.
6612. If no fault message exists, the contact opens without delay.
Important
The alarm relay can be reset without having the fault remedied
(see prog. no. 6710). The alarm relay can also be closed
temporarily by a message which, for example, leads to restart.
Heat circuit pump HC3 Q20: Activating the pump heating circuit HC3.
System pump Q14: Connection of a feed pump.
Heat gen shutoff valve Y4: Connection of a changeover valve for
hydraulic de-coupling of the heat generator from the rest of the heating
system.
Solid fuel boiler pump Q10: Connection of a circulation pump for the
boiler circuit for the connection of a solid fuel boiler.
Time program 5 K13: the relay will be controlled by the time program 5
according to the settings.
Buffer return valve Y15:This valve must be configured for return
temperature increase/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 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 drinking water storage can be charged
from the buffer storage, if is sufficiently hot. This transfer is brought
about by transfer pump Q11.
DHW mixing pump Q35: separate pump for storage circulation during
active legionella function.
