Functional description
Heating and cooling operating mode
Modern heat pump systems often also provide the option of cooling rooms. This function is sup-
ported by the cover by means of the "Heating and cooling" operating mode. In this operating
mode the system permanently regulates the temperature to the set cooling temperature. There
are no time programs in cooling mode. The only way to change the cooling temperature con-
sists in adjusting the temperature parameters, the +/- buttons cannot be used.
In conjunction with a room temperature controller insert, cooling mode is activated by applying
mains power to input terminal "C". With switch inserts, cooling mode is activated by applying
mains power to extension input "1". In general, the heat pump features a corresponding output
or a switch can be used.
Frost protection / temperature drop detection
Ʒ
The frost protection temperature is the minimum temperature regulated by the controller in order
to avoid frost damage. In case of a significant temperature drop, e.g. after opening a window,
the system regulates to the frost protection temperature for a maximum of 30 minutes. This re-
quires the temperature drop detection parameter
Ʒ
to be activated.
