re). As soon as the outdoor temperature exceeds 1°C
the heat circuit is switched off again.
Frost protection - settings range: on, off / Default: on
Switching the frost protection function off or setting the minimum flow tempe-
rature too low can lead to severe damage of the system.
MENU 8.2 MIN. FLOW TEMPERATURE
The minimum flow temperature is the lower limit for the characteristic curve/slope and
as a result of the reference flow temperature of the heat circuit.
Additionally, the min. flow temperature is the reference flow temperature for the frost
protection.
Settings range: 5°C to 30°C / Default: 15°C
MENU 8.3 MAX. FLOW TEMPERATURE
This is used as the upper limit for the reference flow temperature of the heat circuit.
Should the heat circuit temperature exceed this value, the heat circuit is switched off
until the temperature drops below.
Settings range: 30 °C to 105 °C / Default: 45 °C
For safety, the customer must provide an additional limiting thermostat which
is connected to the pumps in series.
MENU 8.4 MAX FLOW 2
Menu 8.4 is activated when Heating circ 2 is selected in menu 9.7.2
Max. flow temperature of the Heating circ 2.
Settings range off to105°C / Default: 45°C
MENU 8.5 ANTI-LEGIONELLA
MENU 8.5.1 AL FUNCTION
Anti-legionella function.
Settings range on/off
MENU 8.5.2 AL TSET
Target temperature for Al heating
Settings range 60°C to 99°C /Default: 70°C
MENU 8.5.3 AL INTERVAL
Interval in days between Al heatings.
Settings range 1 to 28 /Default:7
MENU 8.5.4 AL HEAT
Shows last executed Anti-Legionella heating cycle.

Settings are only necessary in special cases at
the time of initial commissioning by the specia-
list. Incorrect measurement values can lead to
unpredictable errors.
MENU 9.2 COMMISSIONING
Starting the commissioning help guides you in the correct order through the basic set-
tings necessary for commissioning, and provides brief descriptions of each parameter in
the display.
Pressing the "esc" key takes you back to the previous value so you can look at the se-
lected setting again or adjust it if desired. Pressing the "esc" more than once takes you
back to the selection mode, thus cancelling the commissioning help.
May only be started by a specialist during commissioning! Observe the explana-
tions for the the individual parameters in these instructions, and check whether
further settings are necessary for your application.
MENU 9.3 FACTORY SETTINGS
All of the settings that have been made can be reset, thus returning the controller to its
delivery state.
The entire parametrisation, statistics, etc. of the controller will be lostirrevocably.
The controller must then be commissioned once again.
MENU 9.4 EXPANSIONS
This menu can only be selected and used if additional options or expansion modules
have been built into the controller.
The associated supplementary installation, mounting and operation instructions are
then included with the specific expansion.
MENU 9.5 MIXER
Settings are only necessary at the time of initial commissioning by the specialist.
Incorrect measurement values can lead to severe unpredictable errors.
