Solar

Coding
Coding in the delivered condition
Differential, DHW
6E:10 Differential temperature of 10 K
between solar and DHW heating to
start DHW heating by the solar
thermal system
Maximum temperature, DHW
6F:70 Max. DHW temperature limit when
heated by the solar thermal sys-
tem. DHW is heated by the solar
thermal system up to this tempera-
ture.
Buffer differential
70:20 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 of cylinder heat-
ing by the solar thermal system
disabled.
Code only available when DHW
heating is connected to the boiler.
Additional function, runtime
72:0 Circulation pump OFF.
Solar circuit pump, maximum speed
73:100 Maximum permissible speed of so-
lar circuit pump, 100 % of maxi-
mum possible pump speed
Solar circuit pump, minimum speed
74:30 Minimum permissible speed of so-
lar circuit pump, 30 % of maximum
possible pump speed
Nominal flow rate, collector circuit
75:0.0 No flow rate
Possible change
6E:1 Setting range of differential tempera-
to ture in K
6E:50
6F:0 Setting range in °C
to
6F:100
70:1 Setting range in °C
to
70:50
71:0 Start time of the solar additional
to function. Solar additional function:
71:23 Signal for starting the transfer pump
of the solar thermal system. This al-
so heats the lower area of the DHW
cylinder to the required temperature.
Time adjustable from 01:00 h
("71:1") to 23:00 h ("71:23")
72:0 Runtime of the solar transfer pump.
to Adjustable from 1 to 180 min. Only
72:180 available in case of code "71:1 - 23".
73:10 Setting range in %
to
73:100
74:10 Setting range in %
to
74:100
75:0.1 Nominal flow rate of collector circuit
to in l/min. Adjustable from 0.1 l/min to
75:50.0 50 l/min.
