Coding
Coding in the factory set condition
00:8 The solar circuit pump starts when the
collector temperature exceeds the actual
DHW temperature by 8 K.
01:4 The solar circuit pump stops when the
differential between the collector temperature
and the actual DHW temperature is less than
4 K.
02:0 Solar circuit pump (multi stage) without speed
control by solar control module SM1.
03:10 The temperature differential between the
collector temperature and actual DHW
temperature is regulated to 10 K.
04:4 Controller amplification of the speed control
4%/K.
05:10 Minimum speed of the solar circuit pump
10% of the maximum speed.
06:75 Maximum speed of the solar circuit pump
75% of the maximum possible speed.
07:0 Interval function of the solar circuit pump
switched off.
08:60 The solar circuit pump stops when the actual
DHW temperature reaches the maximum
DHW tank temperature 140° F (60° C).
09:130 The solar circuit pump stops if the collector
temperature reaches 266 50 to 194° F
(130° C) (maximum collector temperature
to protect the system components).
0A:5 To protect the system components and heat
transfer medium:
The speed of the solar circuit pump is reduced
if the actual DHW tank temperature is 5 K
below the maximum DHW tank temperature.
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).

00:2 The differential between the actual DHW
to temperature and the start point for the solar
00:30 circuit pump can be adjusted from 2 to 30 K.
01:1 The differential between the actual DHW
to temperature and the stop point for the solar
01:29 circuit pump can be adjusted from 1 to 29 K.
02:1 Solar circuit pump (multi stage) is speed-
controlled with wave pack control.
02:2 Solar circuit pump is speed-controlled with
PWM control.
03:5 The differential temperature control between
to collector temperature and actual DHW
03:20 temperature can be adjusted from 5 to 20 K.
04:1 Controller amplification adjustable from
to 1 to 10%/K.
04:10
05:2 Minimum speed of the solar circuit pump
to is adjustable from 2 to 100%.
05:100
06:1 Maximum speed of the solar circuit pump
to is adjustable from 1 to 100%.
06:100
07:1 Interval function of the solar circuit pump
switched on.
To capture the collector temperature more
accurately, the solar circuit pump starts
for short cycles.

to can be adjusted from 50 to 194° F
08:90 (10 to 90° C).
09:20 The temperature can be adjusted from
to 68 to 392° F (20 to 200° C).
09:200
0A:0 Stagnation time reduction disabled.
0A:1 Value for stagnation time reduction adjustable
to from 1 to 40 K.
0A:40
0B:1 Frost protection function for solar circuit
switched on (not required with Viessmann
heat transfer medium).
0C:0 nt monitoring switched off.
0D:0 Night circulation monitoring switched off.
