Control settings - system definition
7004 Temp. diff. cooling !
The cooling limit defines the value of
the outside temperature, above which
cooling mode commences. Similarly
to the heating limit, this temperature
limit results from the set room tem-
perature plus this temperature differ-
ential.
Note
This parameter is only available if
cooling mode has been enabled via
parameter "Cooling" (7100).
7005 Red.mode t threshold §
Lower temperature limit for "Reduced" operating mode.
If the long-term average outside tem-
perature drops below the specified
value, the control unit switches from
"Reduced" to "Standard" operating
mode (in accordance with EN 12831).
As soon as the outside temperature
rises 2 K above this temperature limit,
"Reduced" operating mode is re-
enabled.
7006 Frost protection t §
Lower temperature limit for frost protection function.
