3.3 Function blocks
Depending on the selected system/variant and other
options e.g. internal heating circuit module, certain re-
lays are already assigned. Relays which are not assigned
can be allocated to one of the 5 function blocks other
uses e.g.(extra valves, stores, heat sources etc ).
Each function block provides 4 functions:
1 temperature differential function
2 thermostat functions
1 timer (with 21 time frames)
Within a function block, these functions can be activated
and combined as required in the menu (Arrangement/
Options/...). All switch-on conditions of all activated
functions have to be fulfilled in order to energise the
relay allocated to the function block (Arrangement/Adj.
values/...). These functions can be compared to swit-
ches connected in series:
The temperature differential function of a function block
has to be activated in order to implement a simple
return preheating function.
Arrangement/Options/DT-Func6 change setting to
„Yes“.
