Vitotronic 100, GC1B Installation and Service
Category 4 "Solar"
Coding in the Delivered Condition
0b:0 Frost protection function for solar circuit
switched off.
0C:1
nt monitoring switched on.
No flow rate captured in the solar circuit,
or flow rate too low.
0d:1 Night circulation monitoring switched on.
Unintentional flow rate is captured in the solar
circuit (e.g. at night).
0E:1 Calculation of solar yield with Viessmann heat
transfer medium.
0F:70 The solar circuit flow rate at maximum pump
speed is 7 L/min.
10:0 Target temperature control switched off
(see coding address "11").
11:50 Set solar DHW temperature 122°F (50°C).
Target temperature control switched on
(code "10:1"):
Temperature at which the solar heated water
in the DHW tank is to be stratified.
Extended control functions set to heat two
DHW tanks (code "20:8"):
The second DHW tank is heated when one
DHW tank reaches its set DHW temperature.
12:10 Minimum collector temperature 50°F (10°C).
The solar circuit pump will only start when the
set minimum collector temperature is exceeded.
Controller amplification of the speed control 4%/K.
20:0 No extended control functions enabled.
22:8 Start temperature differential for central heating
backup: 8 K.
Switching output sS is switched on when the
temperature at sensor / exceeds the
temperature at sensor aÖ by the selected value.

Possible Change
0b:1 Frost protection function for solar circuit switched
on (not required with Viessmann heat transfer
medium).

nt monitoring switched off.
0d:0 Night circulation monitoring switched off.
0E:2 Calculation of solar yield with water as heat transfer
medium (never adjust, as operation is only
possible with Viessmann heat transfer medium).
0E:0 Calculation of solar yield switched off.
0F:1 Flow rate adjustable from
to 0.1 to 25.5 L/min.
0F:255 1 step 0.1 L/min.

20:2 Differential temperature control 2.
20:3 Differential temperature control 2 and auxiliary
function.
20:4 Differential temperature control 2 for central
heating backup.
20:5 Thermostat function.
20:6 Thermostat function and auxiliary function.
20:7 Solar heating via external heat exchanger
without additional temperature sensor.
20:8 Solar heating via external heat exchanger
with additional temperature sensor.
