Coding 2
Solar (continued)
Coding in the factory setting Possible change
09:130 The solar circuit pump stops
if the collector temperature
reaches 266° F (130° C)
(maximum collector temperature
to protect the system
components)
09:20
to
09:200
Temperature adjustable from
68 to 392° F (20 to 200° C).
0A:5 Temperature differential for
stagnation time reduction
(reduction in the speed of the
solar circuit pump to protect
system components and heat
transfer medium) 5 K.
0A:0
to
0A:40
The differential between the
set DHW tank temperature and
the start point for reducing the
stagnation time can be adjusted
from 0 to 40 K.
0B:0 Collector frost protection
function switched off
0B:1 Collector frost protection function
switched on (not required with
Viessmann heat transfer medium).
0C:1
t monitoring switched on.
No flow rate captured in the
solar circuit, or flow rate too
low.
0C:0
t monitoring switched off.
0D:1 Night circulation monitoring
switched on.
Unintentional flow rate is
captured in the solar circuit
(e.g. at night).
0D:0 Night circulation monitoring
switched off.
0E:1 Calculation of solar yield
with Viessmann heat transfer
medium
0E:2 Calculation of solar yield with water
as heat transfer medium (do not
select as operation is only possible
with Viessmann heat transfer
medium).
0E:0 Calculation of solar yield switched
off.
0F:70 The flow rate in the collector
circuit at the maximum pump
speed is set to 1.8 USG (7 L/
minute).
0F:1
to
0F:255
Flow rate in the collector
circuit adjustable from 1.6 to 6.7
USG/minute (0.1 to 25.5 L/minute).
10:0 Target temperature control
switched off (see coding
address “11”).
10:1 Target temperature control
switched on.
