Legionella function circ pump
(1647)
-
On
: The circulation pump will be switched on in case of active legionella func-
tion.
Caution!
There exists a hazard of scalding at the tapping locations in case of acti-
vated legionella function.
Circulating pump release
(1660)
-
Time program 3
The DHW circulating pump is enabled subject to time program
3 (see prog. no. 540 to 556).
-
DHW release
: The DHW circulating pump will be enabled when DHW heating
has been enabled.
-
Time program 4
The DHW circulating pump will be enabled subject to time pro-
gram 4.
Circulating pump cycling
(1661)
The circulating pump will be switched on for 10 minutes and off for 20 minutes
within the release time.
Circulation setpoint
(1663)
In case of undercutting the circulation setpoint (Standard value: 45°C), the circu-
lation pump will be switched on for 10 minutes within the release time. When
reaching the circulation setpoint, but at the earliest 10 minutes later, the pump is
switched off. For this function, the connection of a sensor in the circulation return
is necessary (inputs BX, program no. 5930-5933).
Optg mode changeover
(1680)
Using external switching above the entrances H1-H5 it can be selected into which
operating mode is switched into.
-
None
: the function is switched off.
8.4.8 Consumer circuit and swimming pool circuit
Flow temp setp cons request
(1859, 1909, 1959)
Setting of the flow setpoint is done with this function, which is effective during
active request of the consumer circuit.
DHW charging priority
(1874, 1924, 1974)
Setting, if the connected consumerscircuit pump should be used with priority for
domestic hot water charging.
Excess heat draw
(1875, 1925, 1975)
If an excess temperature discharge is activated, the excess energy can be dis-
charged through a consumercircuit of the room heating. This can be separately
set for each consumercircuit.
With buffer storage tank
(1878, 1928, 1978)
-
No
: the consumer circuit is fed directly from the boiler.
-
Yes
: the consumer circuit is fed directly from the charging buffer.
With prim contr/system
pump
(1880, 1930, 1980)
-
No
: the consumer circuit will be fed without primary control unit/feed pump
-
Yes
: the consumer circuit will be charged from the primary controller on/with
the system pump.
8.4.9 Swimming pool
Setpoint solar heating
(2055)
When using solar energy, the swimming pool is heated to the setpoint set here.
Setpoint source heating
(2056)
When using the generator heating, the swimming pool is heated to the setpoint
set here.
