Cosmo Multi 2 - 4. Functions and Options - Function Blocks; Function Blocks Overview; Function Block Assignment and Sensors

100
Depending on the selected basic system and activated
options, there are up to 5 function blocks including
thermostat functions, timer and differential functions.
With these, further components or functions e.g. solid
fuel boiler, heating backup and DHW afterheating can be
implemented (see 3.3 for further examples).
Function blocks are assigned to the relays (see 3.5) and
the relay cannot be changed. Each function block has
allocated sensors that can be changed in the expert
menu if needed. It is also possible to „double up“ in
the programming and use a sensor already allocated
to another function.
Within a function block the functions are intercon-
nected (AND gate). This means that the conditions of all
the activated functions have to be fulfilled for switching
the allocated relay. As soon as one condition is not
fulfilled, the relay is switched off.
