Codes
Code 1
(cont.)
Coding in the delivered condition
Buffer differential
70:10
Differential temperature of 20 K
between solar and heating water
buffer cylinder to start heating wa-
ter buffer cylinder by the solar ther-
mal system
Additional function, solar
71:0
Additional function solar: Circula-
tion pump for heat transfer of the
DHW cylinder disabled.
Coding is available if the output of
the circulation pump for transfer of
heat (UP) is available on the HKK
PCB. See "connection options at
the HKK PCB and extension kits
via KM-BUS"
Additional function, runtime
72:0
Circulation pump for heat transfer
"Off"
Solar circuit pump maximum speed
73:100
Maximum permissible speed of so-
lar circuit pump out of 100 % of
maximum possible pump speed
Solar circuit pump minimum speed
74:30
Minimum permissible speed of so-
lar circuit pump out of 30 % of
maximum possible pump speed
Nominal flow rate, collector circuit
75:0.0
No flow rate
Solar collector maximum temperature
76:140
Maximum temperature in the solar
collector. The Solar group is shut
down if the max. temperature is
exceeded.
When the temperature falls below
the set max. temperature by 10 K,
the Solar group restarts.
104
Possible change
70:1
Adjustable value in °C
to
70:50
71:0
Start time for the solar additional
to
function.
71:23
Additional function solar: Release of
the circulation pump for heat transfer
of the DHW cylinder. The circulation
pump (UP) of the solar thermal sys-
tem can heat up the lower area of
the DHW cylinder to the desired
temperature.
Time adjustable from 01:00 h
("71:1") to 23:00 h ("71:23").
The time of the function must be
within the enable times for DHW
heating.
72:0
Running time of the circulation pump
to
for solar heat transfer
72:180
Adjustable value in minutes
Only active in conjunction with code
"71:1 - 23".
73:10
Setting in %
to
73:100
74:10
Adjustable value in %
to
74:100
75:0.1
Nominal flow rate of the collector cir-
to
cuit
75:50.0
Adjustable value in l/min
76:50
Adjustable value in °C
to
76:150
