Simple heating curve
The simple heating curve (Control type: External simple) is a
simplification of the curved heating curve as a straight line. The
straight line is described by two points ( ).
8.3 Function test menu
Using this menu, the pump/valve for each assigned heating
zone can be tested. They are tested by setting various setting
values. You can check whether the pump/valve responds
appropriately by observing the response of the corresponding
component. If Activation is set to YES in this menu, the normal
heating mode is interrupted in the entire system. All settings
are saved. The settings in this menu are only temporary and
revert to the respective default settings as soon as Activation
is set to NO or the Function Test menu is closed.

Control range Functional description
Activation NO | YES NO: The actuators revert to their previously stored position so that the system starts
up again after the function tests in the same condition as when shut down.
YES: The instantaneous operating status (mixer: actuation stroke; pump: stage or
speed) of the actuators in the system is saved. All actuators in the system switch to
the test mode.
System pump 0 (in %) 0 | 100 (in %) 0: System pump for heating zones with valves not running (switched off).
100: System pump for heating zones with valves running at maximum speed.
HC Pump 0 (in %) 0 | 100 (in %) 0: Heating pumps not running/zones valves closed (off).
100: Heating pumps running/zones valves open (on).
