Coding
Coding in the factory set condition
Speed control solar circuit pump
02:0 Solar circuit pump (multi stage) without speed
control by solar control module SM1.
DHW tank maximum temperature
08:60 The solar circuit pump stops when the actual
DHW temperature reaches the maximum
DHW tank temperature 140° F (60° C).
Stagnation time reduction
0A:5 To protect system components and heat
transfer medium: the speed of the solar
circuit pump is reduced if the actual DHW
temperature is 5 K below the maximum DHW
tank temperature.
Flow rate solar circuit
0F:70 The solar circuit flow rate at maximum pump
speed is 7 L/min.
20:0 No extended control functions enabled.
Note: The solar group is only displayed if a solar control
module, type SM1, is connected.
Possible change
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.
08:10 The maximum DHW tank temperature
to is adjustable from 50 to 194° F (10 to 90° C).
08:90
0A:0 Stagnation time reduction is disabled.
0A:1 Value for stagnation time reduction is adjustable
to from 1 to 40 K.
0A:40
0F:1 Flow rate adjustable from 0.1 to 25.5 L/min;
to 1 step 0.1 L/min.
0F:255
20:1 Additional function for DHW heating.
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.
20:9 Solar heating of two DHW tanks.
